Feasibility study of an electronic portal imaging based in vivo dose verification system for prostate stereotactic body radiotherapy

Stereotactic body radiation therapy (SBRT) is capable of delivering very large and precise dose of radiation, and has emerged as a primary treatment for low and intermediate risk prostate cancer [1,2]. Accurate imaging and tracking of the target regions allows clinicians to reduce treatment margins and maximally spare rectum, bladder, urethra and penile bulb [3]. However, very sharp dose gradients and the proximity of critical structures to prostate requires precise verification of treatment plans [4,5].
