Abstract

ABSTRAK

Telah dilakukan penelitian mengenai studi awal pengujian perangkat kamera gamma dual head model pencitraan Single Photon Emission Computed Tomography (SPECT) menggunakan sumber radiasi high energy I131 di bidang Teknik Nuklir Kedokteran (TNK) Pusat Teknologi Keselamatan dan Metrologi Radiasi (PTKMR) Badan Tenaga Nuklir Nasional (BATAN), Jakarta Selatan.  Pada penelitian ini dilakukan pengujian dengan mencacah I131 dan melihat pengaruh yang dihasilkan dari perubahan sudut terhadap laju cacahan menggunakan kolimator High Energy General Purpose (HEGP), tanpa kolimator, phantom linier, dan phantom jaszczak. Selain itu dilakukan analisa akumulasi sumber radiasi menggunakan teknik Region of Interest (ROI). Dari hasil pengujian didapatkan nilai laju cacahan pada saat tanpa kolimator lebih tinggi dibandingkan saat menggunakan kolimator HEGP, serta didapatkan bahwa detektor kamera gamma menangkap paparan sumber radiasi dengan baik dan tidak terjadi kerusakan pada detektor

Kata kunci: kamera gamma dual head, SPECT, kolimator HEGP, phantom linier, phantom jaszczak.

Abstract

Preliminary study on the performance of a dual head Single Photon Emission Computed Tomographic (SPECT) gamma camera at PTKMR-BATAN has been examined by using high energy radiation from I131. The performance was investigated from the influence of angle change on count rate for the system with High Energy General Purpose (HEGP) collimator, without any collimator, and with linier and jaszczak phantoms. Moreover, the accumulation of radiation was analyzed by using the Region of Interest (ROI) technique. It was found that the count rate for the measurement without any collimator was larger than the measurement with HEGP collimator. In addition, the result showed that the gamma camera detector captures the radiation exposure well, indicating that no damage occurs in the detector.

Keywords: dual head gamma camera, HEGP collimator, I131, jaszczak phantom, linier phantom, SPECT.
