Failure Mode and Effects Analysis (FMEA) for Experimental Use of FLASH on a Clinical Accelerator Open
Background: Use of a linear accelerator in ultra-high dose rate (UHDR) mode can provide a conduit for wider access to UHDR FLASH effects, sparing normal tissue, but care needs to be taken in the use of such systems to ensure errors are min…
