MRCAT Pelvis
MR-RT clinical application
MRCAT Pelvis lets you plan radiation therapy using MRI as a single modality solution. Within just one MR exam, MRCAT Pelvis provides excellent soft-tissue contrast for target and OAR delineation, and continuous Hounsfield units for dose calculations.
MRCAT (MR for Calculating ATtenuation) data can be used for export to treatment planning systems for CT-equivalent** dose calculations. In addition, MR-based imaging enables CBCT-based positioning based on soft-tissue contrast with the look and feel of CT.

Features
Put Philips MR-only radiotherapy to work today
To successfully bring MR-only radiotherapy into your clinical routine, we recognize that you must look beyond the imaging itself and address important steps such as patient marking, position verification, and quality assurance. We are prepared to support you throughout this process. To this end, we offer dedicated workflow descriptions, best practice sharing and tailored training support, designed to provide assistance as you adopt this new treatment paradigm.
Accuracy in dose planning
MRCAT images have high geometric accuracy* and validation studies have shown that MRCAT-based dose plans are robust and as accurate** as CT-based plans promoting confidence in dose planning.
Unleash the real power of MR simulation
MRCAT Pelvis lets you plan radiation therapy for male and female pelvic cancer patients with soft-tissue tumors using MRI as a single-modality solution. This not only extends the benefits of MRI’s outstanding soft-tissue contrast to radiotherapy planning, but it also eliminates arduous, error-prone CT-MRI registration from the process, reducing uncertainties and complexity.

- The state-of-the-art Ingenia MR-RT platform featuring Ambition 1.5T and Elition 3.0T MR systems meets specific RT needs by providing high-quality MR images acquired in the treatment position. Smoothly integrate MRI through a comprehensive solution that considers your whole workflow, even for MR-only radiotherapy.
- MRCAT Brain clinical application allows the use of MRI as the primary imaging modality for radiotherapy planning of primary and metastatic tumors in the brain without the need for CT. Detailed anatomical information for contouring and attenuation maps for dose calculations are both obtained from a single, submillimeter resolution 3D T1W mDIXON MR sequence. Artificial Intelligence (AI) is used for fast computation of continuous Hounsfield units directly on the MR console.
- As a plug-in clinical application to Ingenia MR-RT, MRCAT Prostate + Auto-Contouring provides attenuation maps and automated, MR-based contours of prostate and organs at risk in as little as 20 minutes – all in a repeatable ‘one-click’ workflow.
