Abstract

Multiple vendors are now offering real-time MRI-guided radiotherapy systems. Quality assurance of small fields delivered with an MR-RT system requires detectors with high spatiotemporal resolution, and magnetic insensitivity. High spatial resolution is required to characterise the asymmetric penumbra that transverse designs demonstrate. In this work the authors describe the characterisation of the dosimetric performance of a monolithic silicon strip detector mounted to a flexible polymide (Kapton) printed circuit board intended for use in MRI-linac dosimetry.
