Abstract

Developing robust deep learning models for fetal ultrasound image analysis requires comprehensive, high-quality datasets to effectively learn informative data representations within the domain. However, the scarcity of labelled ultrasound images poses substantial challenges, especially in low-resource settings. To tackle this challenge, we leverage synthetic data to enhance the generalizability of deep learning models. This study proposes a diffusion-based method, Fetal Ultrasound LoRA (FU-LoRA), which involves fine-tuning latent diffusion models using the LoRA technique to generate synthetic fetal ultrasound images. These synthetic images are integrated into a hybrid dataset that combines real-world and synthetic images to improve the performance of zero-shot classifiers in low-resource settings. Our experimental results on fetal ultrasound images from African cohorts demonstrate that FU-LoRA outperforms the baseline method by a 13.73% increase in zero-shot classification accuracy. Furthermore, FU-LoRA achieves the highest accuracy of 82.40%, the highest F-score of 86.54%, and the highest AUC of 89.78%. It demonstrates that the FU-LoRA method is effective in the zero-shot classification of fetal ultrasound images in low-resource settings. Our code and data are publicly accessible on GitHub.

Method

Our FU-LoRA method: Fine-tuning the pre-trained latent diffusion model (LDM) [2] using the LoRA method on a small fetal ultrasound dataset from high-resource settings (HRS). This approach integrates synthetic images to enhance generalization and performance of deep learning models. We conduct three fine-tuning sessions for the diffusion model to generate three LoRA models with different hyper-parameters: alpha in [8, 32, 128], and r in [8, 32, 128]. The merging rate alpha/r is fixed to 1. The purpose of this operation is to delve deeper into LoRA to uncover optimizations that can improve the model's performance and evaluate the effectiveness of parameter r in generating synthetic images.

Datasets

The Spanish dataset (URL) in HRS includes 1,792 patient records in Spain [1]. All images are acquired during screening in the second and third trimesters of pregnancy using six different machines operated by operators with similar expertise. We randomly selected 20 Spanish ultrasound images from each of the five maternal–fetal planes (Abdomen, Brain, Femur, Thorax, and Other) to fine-tune the LDM using LoRA technique, and 1150 Spanish images (230 x 5 planes) to create the hybrid dataset. In summary, fine-tuning the LDM utilizes 100 images including 85 patients. Training downstream classifiers uses 6148 images from 612 patients. Within the 6148 images used for training, a subset of 200 images is randomly selected for validation purposes. The hybrid dataset employed in this study has a total of 1150 Spanish images, representing 486 patients.

We create the synthetic dataset comprising 5000 fetal ultrasound images (500 x 2 samplers x 5 planes) accessible to the open-source community. The generation process utilizes our LoRA model Rank r = 128 with Euler and UniPC samplers known for their efficiency. Subsequently, we integrate this synthetic dataset with a small amount of Spanish data to create a hybrid dataset.

Implementation Details

The hyper-parameters of LoRA models are defined as follows: batch size to 2; LoRA learning rate to 1e-4; total training steps to 10000; LoRA dimension to 128; mixed precision selection to fp16; learning scheduler to constant; and input size (resolution) to 512. The model is trained on a single NVIDIA RTX A5000, 24 GB with 8-bit Adam optimizer on PyTorch.

Abstract:

Sharing data from clinical studies can facilitate innovative data-driven research and ultimately lead to better public health. However, sharing biomedical data can put sensitive personal information at risk. This is usually solved by anonymization, which is a slow and expensive process. An alternative to anonymization is sharing a synthetic dataset that bears a behaviour similar to the real data but preserves privacy. As part of the collaboration between Novartis and the Oxford Big Data Institute, we generate a synthetic dataset based on COSENTYX Ankylosing Spondylitis (AS) clinical study. We apply an Auxiliary Classifier GAN (ac-GAN) to generate synthetic magnetic resonance images (MRIs) of vertebral units (VUs). The images are conditioned on the VU location (cervical, thoracic and lumbar). In this paper, we present a method for generating a synthetic dataset and conduct an in-depth analysis on its properties of along three key metrics: image fidelity, sample diversity and dataset privacy.

Gradmag-Syn-Car ---> Gradmag of Cartoonish images (2500 images)=============================================================================Each folder contains the images and their respective groundtruth poses in the following format [ImageName X Y Z w p q r].To generate the synthetic data-set, we define a trajectory in the 3D indoor model. The points in the trajectory serve as the ground truth poses of the synthetic images. The height of the trajectory was kept in the range of 1.5–1.8 m from the floor, which is the usual height of holding a camera in hand. Artificial point light sources were placed to illuminate the corridor (except for Edge render images). The length of the trajectory was approximately 30 m. A virtual camera was moved along the trajectory to render four different sets of synthetic images in Blender*. The intrinsic parameters of the virtual camera were kept identical to the real camera (VGA resolution, focal length of 3.5 mm, no distortion modeled). We have rendered images along the trajectory at 0.05 m interval and ± 10° tilt.The main difference between the cartoonish (Syn-car) and photo-realistic images (Syn-pho-real) is the model of rendering. Photo-realistic rendering is a physics-based model that traces the path of light rays in the scene, which is similar to the real world, whereas the cartoonish rendering roughly traces the path of light rays. The photorealistic textured images (Syn-pho-real-tex) were rendered by adding repeating synthetic textures to the 3D indoor model, such as the textures of brick, carpet and wooden ceiling. The realism of the photo-realistic rendering comes at the cost of rendering times. However, the rendering times of the photo-realistic data-sets were considerably reduced with the help of a GPU. Note that the naming convention used for the data-sets (e.g. Cartoonish) is according to Blender terminology.An additional data-set (Gradmag-Syn-car) was derived from the cartoonish images by taking the edge gradient magnitude of the images and suppressing weak edges below a threshold. The edge rendered images (Syn-edge) were generated by rendering only the edges of the 3D indoor model, without taking into account the lighting conditions. This data-set is similar to the Gradmag-Syn-car data-set, however, does not contain the effect of illumination of the scene, such as reflections and shadows.*Blender is an open-source 3D computer graphics software and finds its applications in video games, animated films, simulation and visual art.

By leveraging synthetic images, enterprises can overcome these barriers, generating diverse, scalable, and bias-mitigated datasets for training and validating AI models. This is particularly critical in sectors such as healthcare, finance, and autonomous vehicles, where real-world data is both sensitive and scarce. The ability to generate synthetic images that closely mimic real-world scenarios, while ensuring privacy, is unlocking new opportunities for innovation and operational efficiency across industries.

Furthermore, the increasing sophistication of generative models, such as Generative Adversarial Networks (GANs) and diffusion models, has significantly enhanced the realism and utility of synthetic images. These technological advancements are enabling more nuanced privacy preservation techniques, such as differential privacy and federated learning, which further bolster the appeal of synthetic data solutions. As a result, the market is witnessing heightened investment from both established technology vendors and emerging startups, leading to rapid product development, ecosystem expansion, and competitive differentiation.

OverviewThis is a set of synthetic overhead imagery of wind turbines that was created with CityEngine. There are corresponding labels that provide the class, x and y coordinates, and height and width (YOLOv3 format) of the ground truth bounding boxes for each wind turbine in the images. These labels are named similarly to the images (e.g. image.png will have the label titled image.txt)..UseThis dataset is meant as supplementation to training an object detection model on overhead images of wind turbines. It can be added to the training set of an object detection model to potentially improve performance when using the model on real overhead images of wind turbines.WhyThis dataset was created to examine the utility of adding synthetic imagery to the training set of an object detection model to improve performance on rare objects. Since wind turbines are both very rare in number and sparse, this makes acquiring data very costly. This synthetic imagery is meant to solve this issue by automating the generation of new training data. The use of synthetic imagery can also be applied to the issue of cross-domain testing, where the model lacks training data on a particular region and consequently struggles when used on that region.MethodThe process for creating the dataset involved selecting background images from NAIP imagery available on Earth OnDemand. These images were randomlyselected from these geographies: forest, farmland, grasslands, water, urban/suburban,mountains, and deserts. No consideration was put into whether the background images would seem realistic. This is because we wanted to see if this would help the model become better at detecting wind turbines regardless of their context (which would help when using the model on novel geographies). Then, a script was used to select these at random and uniformly generate 3D models of large wind turbines over the image and then position the virtual camera to save four 608x608 pixel images. This process was repeated with the same random seed, but with no background image and the wind turbines colored as black. Next, these black and white images were converted into ground truth labels by grouping the black pixels in the images.

The ArtiFact dataset is a comprehensive collection of 2.5 million real and synthetic images across diverse categories. It includes real images from 8 sources and synthetic images generated using 25 methods, such as GANs, diffusion models, and other generators.

TrueFace is a first dataset of social media processed real and synthetic faces, obtained by the successful StyleGAN generative models, and shared on Facebook, Twitter and Telegram.

Images have historically been a universal and cross-cultural communication medium, capable of reaching people of any social background, status or education. Unsurprisingly though, their social impact has often been exploited for malicious purposes, like spreading misinformation and manipulating public opinion. With today's technologies, the possibility to generate highly realistic fakes is within everyone's reach. A major threat derives in particular from the use of synthetically generated faces, which are able to deceive even the most experienced observer. To contrast this fake news phenomenon, researchers have employed artificial intelligence to detect synthetic images by analysing patterns and artifacts introduced by the generative models. However, most online images are subject to repeated sharing operations by social media platforms. Said platforms process uploaded images by applying operations (like compression) that progressively degrade those useful forensic traces, compromising the effectiveness of the developed detectors. To solve the synthetic-vs-real problem "in the wild", more realistic image databases, like TrueFace, are needed to train specialised detectors.

Synthetic Training Data Market Outlook

According to our latest research, the global synthetic training data market size in 2024 is valued at USD 1.45 billion, demonstrating robust momentum as organizations increasingly adopt artificial intelligence and machine learning solutions. The market is projected to grow at a remarkable CAGR of 38.7% from 2025 to 2033, reaching an estimated USD 22.46 billion by 2033. This exponential growth is primarily driven by the rising demand for high-quality, diverse, and privacy-compliant datasets that fuel advanced AI models, as well as the escalating need for scalable data solutions across various industries.

One of the primary growth factors propelling the synthetic training data market is the escalating complexity and diversity of AI and machine learning applications. As organizations strive to develop more accurate and robust AI models, the need for vast amounts of annotated and high-quality training data has surged. Traditional data collection methods are often hampered by privacy concerns, high costs, and time-consuming processes. Synthetic training data, generated through advanced algorithms and simulation tools, offers a compelling alternative by providing scalable, customizable, and bias-mitigated datasets. This enables organizations to accelerate model development, improve performance, and comply with evolving data privacy regulations such as GDPR and CCPA, thus driving widespread adoption across sectors like healthcare, finance, autonomous vehicles, and robotics.

Another significant driver is the increasing adoption of synthetic data for data augmentation and rare event simulation. In sectors such as autonomous vehicles, manufacturing, and robotics, real-world data for edge-case scenarios or rare events is often scarce or difficult to capture. Synthetic training data allows for the generation of these critical scenarios at scale, enabling AI systems to learn and adapt to complex, unpredictable environments. This not only enhances model robustness but also reduces the risk associated with deploying AI in safety-critical applications.

Data Synthesis Pipeline:

We provide the Blender 3.1 project files and Python source code of our data synthesis pipeline pipeline.zip, accompanied by the FastCUT models used for synthetic-to-real domain translation models.zip. For the synthesis of new shelf images, a product assortment list and product images must be provided in the corresponding directories products/assortment/ and products/img/. The pipeline expects product images to follow the naming convention c.png, with c corresponding to a GTIN or generic class label (e.g., 9120050882171.png). The assortment list, assortment.csv, is expected to use the sample format [c, w, d, h], with c being the class label and w, d, and h being the packaging dimensions of the given product in mm (e.g., [4004218143128, 140, 70, 160]). The assortment list to use and the number of images to generate can be specified in generateImages.py (see comments). The rendering process is initiated by either executing load.py from within Blender or within a command-line terminal as a background process.
