Cost Minimisation Analysis: Kilovoltage Imaging with Automated Repositioning Versus Electronic Portal Imaging in Image-guided Radiotherapy for Prostate Cancer

Treatment time is less on KVI units compared with EPI units. This is probably due to automation of couch shift and faster evaluation of imaging on KVI units. Annual running costs greatly outweigh initial setting up costs and therefore the cost per fraction was less with KVI, despite higher initial costs. The selection of appropriate IGRT equipment can make IGRT practical within radiotherapy departments.
