Gamma Panel is an essential tool used in the field of radiation therapy to ensure the accuracy of delivered treatment doses. It is a quality assurance technique that compares the planned radiation dose distribution with the actual dose distribution received by the patient.The Gamma Panel consists of a grid of points representing the dose distribution in a specific area. These points are compared between the planned dose distribution and the measured dose distribution using a mathematical algorithm. The results are then displayed as a pass/fail percentage based on a set criteria, usually requiring a threshold of 3% dose difference and a 3mm distance-to-agreement.By analyzing the Gamma Panel results, radiation therapists and physicists can identify any discrepancies between the planned and delivered dose distributions. This allows for adjustments to be made to ensure the patient receives the intended treatment with maximum accuracy and precision.The use of the Gamma Panel is crucial in modern radiation therapy practices as it provides a comprehensive evaluation of treatment delivery accuracy. Without this quality assurance tool, there is a risk of underdosing or overdosing patients, leading to potential harmful side effects or ineffective treatment outcomes.In conclusion, the Gamma Panel plays a vital role in ensuring the quality and safety of radiation therapy treatments. By providing a quantitative analysis of the dose distribution, it helps to minimize errors and improve treatment outcomes for patients. Its use is a standard practice in radiation therapy departments around the world, contributing to the overall success and efficacy of cancer treatment.
