Generate Your Own DICOM Test Images
With this simulation tool, you can generate DICOM test images that mimic the acquisition conditions of real systems, helping you assess quality control tools or perform personal measurements. This user-friendly application simplifies complex image generation processes, providing immediate visual feedback and in-depth customization.
Here’s a look at the key features:
1. Imaging System Selection
Users can select from popular imaging systems like the AS1200, AS1000, or AS500, with each system offering unique characteristics and image acquisition capabilities. This step allows you to simulate the exact conditions you would experience in real-world scenarios.
2. Predefined and Custom Test Models
Once the imaging system is chosen, users can select a test model from predefined templates such as:
- Simple Open Field
- Offset Field
- Winston-Lutz
- VMAT with Multiple Fields
- Picket Fence
- Starshot
For those needing a completely personalized test, the Custom Model option allows full control over the parameters.

3. Full Parameter Customization
The customization of parameters is where this tool truly shines. Using interactive sliders, users can adjust specific aspects of the image simulation, such as:
- Field Dimensions: Adjust the height and width of the field from 10 to 300 mm.
- Gaussian Filter Sigma: Fine-tune the sigma value of the Gaussian filter for different effects.
- Noise Parameters: Control noise levels by setting the mean and standard deviation.
- Special Parameters: Specific to tests like Winston-Lutz, where you can adjust Cone Size and BB Size.
These options make it easy to replicate various imaging conditions and test their effects on your quality assurance processes.
4. Real-Time Visualization
As you tweak the parameters, the system provides real-time visual feedback. The generated image dynamically updates to reflect the changes, allowing you to fine-tune the simulation to perfection.
5. Adding DICOM Metadata
In addition to generating the image, the tool also allows you to embed specific DICOM metadata. This can include acquisition details, system specifications, and other relevant medical data, making it easy to integrate these simulated images into existing workflows for further analysis.
6. Export and Download Your Results
Once satisfied with the configuration, you can export the generated images in various formats, including DICOM. These files can be downloaded for later use, making it easy to revisit or share results with colleagues for further analysis.
