Elekta Unity System
摘要
The excellent soft-tissue contrast of magnetic resonance (MR) images, and the speed and frequency with which the patient can be imaged, allows clear visualization of the target and nearby organs at risk at multiple time points over the course of each treatment. A radiotherapy linac combined with MR imaging enables treatment plan adaptation and considering the patient’s daily anatomy, achieving a greater accuracy of dose delivery to the targets while sparing healthy tissue. This chapter describes the components of the Elekta Unity 1.5T MR-Linac system, including the introduction of MRgRT to a department, staff training, machine installation, quality assurance procedures, and MRgRT treatment workflows.
