At the 60th annual meeting of the American Society for Radiation Oncology (ASTRO), Oct. 21-24 in San Antonio, USA, Siemens Healthineers unveiled the Magnetom RT Pro edition for Magnetom Sola – a version of the company’s new 1.5 Tesla (1.5T) magnetic resonance imaging (MRI) scanner that is designed for assistance in radiation therapy (RT) treatment planning. In addition to BioMatrix technology, which addresses patients’ anatomical and physiological differences to overcome unwanted exam variability, the new scanner includes hardware and software that supports optimal treatment planning.
The Magnetom RT Pro edition for Magnetom Sola has an all-new magnet as well as a system architecture designed for extremely high performance and long-term stability. The RT Dot engine predefines RT strategies, automatically corrects for image distortion to improve spatial integrity, and automatically reconstructs axial images to enable direct processing of all data in RT planning software.
Additionally, RESOLVE software reduces distortions associated with MR diffusion imaging by a factor of three, enabling the use of these images in the dose planning process for the linear accelerator. An interface with RT positioning lasers supports accurate patient positioning.
The scanner’s new, dedicated RT post-planning software, syngo.via RT Image Suite, permits the calculation of synthetic computed tomography (CT) images derived from MR images. These synthetic CT images provide essential information for patients with brain and prostate tumors that typically had been acquired with CT, eliminating the need for patients to lie on the treatment bed for two separate imaging sessions. Syngo.via RT Image Suite is also new to the RT Pro Edition for Magnetom Vida, the 3T scanner for assistance in RT planning that debuted at ASTRO 2017.
“Magnetom RT Pro edition for Magnetom Sola will set new standards for MRT imaging for radiation therapy planning. With syngo.via RT Image Suite, radiation therapy planning can easily be enriched with detailed anatomical and functional soft-tissue contrast information of MRT images. The new scanner will support our customers in increasing their institution’s RT planning capabilities and in improving patient outcomes as well as pave the way for more precise and reproducible RT planning,” said Gabriel Haras, Head of Radiation Oncology at Siemens Healthineers.
