Application of high-resolution radiochromic film dosimetry in verifying a small-field stereotactic radiosurgery plan

Appl Radiat Isot. 2006 Aug;64(8):934-9. doi: 10.1016/j.apradiso.2006.03.011. Epub 2006 May 12.

Abstract

A high-resolution radiochromic film dosimetry (Hr-RCFD) method has been applied to verify a small-field stereotactic radiosurgery (SRS) plan. This was done by exposing a RCF in a Perspex head phantom undergoing the same treatment plan as the patient. The dose distribution obtained by the Hr-RCFD was verified against that calculated by the stereotactic treatment planning system and the result was satisfactory. The Hr-RCFD method has been found to be an accurate and practical tool in verifying small-field SRS plans.
