Abstract
In modern radiotherapy, advanced dose distribution techniques are being widely implemented. The primary goal of these techniques is to deliver the maximum dose to the target area while minimizing exposure to nearby healthy tissues and organs at risk (OAR). Due to their complexity, these techniques demand rigorous dosimetry verification. In dynamic dose distribution, there are instances where the delivered dose may match the planned dose in some regions but different in others. As a result, verifying treatment plans involving intensive and dynamic dose distributions requires a method capable of measuring doses at multiple points simultaneously. Gafchromic films are among effective tools for measuring relative doses. In recent years, the use of gafchromic films has become more prevalent. These films offer the advantage of being self-developing, eliminating the need for chemical processing or darkroom conditions, making them an efficient option for dosimetry verification of advanced techniques in radiotherapy. In Albania the only radiotherapy center that use it, is the department of medical physics to American Hospital Tirana.
