Study of radiation distribution on small field using multiple detectors

---

Radiation therapy is considered an alternative way of of treating patients that have a medical condition from benign tumors and malignant cell growth such as cancer. Compared to chemical therapy (chemotherapy) or through surgery procedures, radiation therapy is a non intravenous procedure. Here by using Linear Accelerator (Linac), it delivers ionizing radiation in the form of energy, such as x-ray beam, photon beam and electron beam in various level of energy depending on the object and purpose. However due to the up-and-coming technologies in radiotherapy, the usage of advance techniques such as Intensity Modulated Radiotherapy (IMRT) and Stereotactic Radiography (SRS) requires specific small beams (small field size) but high dose in delivering the treatment. From the study it was found out that by experimenting on different detectors with different field sizes, not all detectors can measure small field size. Only small sizes detectors like TLD and array detector are able to measure suitably. That is why accuracy in dose delivery in small field sizes is important. In conclusion, in order to ensure its accurateness, a suitable detector is required.
