MRI Planner is a software application developed to generate synthetic CT images and organ-at-risk (OAR) delineations from standard MRI data. The software is intended to be used in MRI-only radiotherapy planning workflows.

• Generates synthetic CT images for brain, head-neck, and pelvis regions using the deep learning-based Transfer Function Estimation (TFE) algorithm.
• Produces automatically generated OAR delineations for prostate cases.
• Operates using a single standard MRI sequence.
• Supports inclusion of fiducial marker data in synthetic CT output for use in positioning workflows.
• Does not require additional training or customization of the algorithm at the clinic.
• Uses standardized DICOM files for image input and output.

MRI Planner is CE-marked and FDA 510(k)-cleared for use in radiotherapy planning of the brain, head-neck, and pelvis. Ongoing product development aims to extend its capabilities to additional areas of clinical relevance. MRI Planner is designed for clinics seeking to implement MRI-only radiotherapy planning using standardized and approved tools.

MRI Planner uses deep learning-based methods for generating synthetic CT images and organ-at-risk (OAR) delineations from MRI data. The software applies pre-trained neural networks and image processing algorithms to create sCT images for brain, head-neck, and pelvis regions, as well as automated OAR contours for prostate radiotherapy planning. Output data is provided in standard DICOM format to support compatibility with commonly used radiotherapy planning systems.
