Features
Accuracy in dose planning
The MRCAT Prostate scanning protocol and generation algorithms have been designed with the strict accuracy requirements of RT in mind. MRCAT Prostate images have high geometric accuracy* and validation studies have shown that MRCAT-based dose plans are robust and equivalent** to CT-based plans promoting confidence in dose planning.
Automatic generation of synthetic CT images
MRCAT Prostate automatically generates attenuation maps using the high-resolution mDIXON scan as source. Smart, validated algorithms enable automatic tissue segmentation and assignment of Hounsfield Units to deliver MRCAT images with CT-like density information for dose calculations - directly on the MR console.
Fast, consistent imaging protocol
A dedicated, standardized imaging protocol includes a T1W mDIXON XD and a T2W TSE scan as source data for the generation of MRCAT (MR for Calculating ATtenuation) density maps and MR-based Auto-Contouring. Compressed SENSE acceleration keeps the total scan time short, which promotes patient comfort by minimizing time in the scanner and helps to boost productivity.

- 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.
- 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.
- The Philips Ingenia MR-RT XD platform harnesses the power and value of MRI for radiation therapy planning. It has been designed around the needs of radiation oncology, with ease-of-use, streamlined integration, and versatility in mind. Central to that concept is the ability to define a tailored approach with customizable functionality that meets your individual clinical, workflow, and budgetary requirements – all to provide better patient care.
