Pemeriksaan ct scan abdomen pada pasien dewasa dilaksanakan untuk memperkirakan paparan dosis yang diterima abdomen selama proses scanning agar tidak melebihi nilai batas dosis yang ditetapkan bapeten. tujuan dari penelitian ini mengetahui besarnya esd yang diterima oleh pasien pemeriksaan abdomen di rsudza menggunakan ct-scan serta untuk mengetahui apakah esd yang diterima pasien pemeriksaan abdomen menggunakan ct-scan di instalasi radiologi rsudza sesuai dengan standar ketetapan. penelitian ini dilakukan menggunakan x-ray multimeter dan ct scan merk siemens somathom emotion 128 slice, jumlah pasien pada penelitian ini 25 orang, parameter pengukuran yang digunakan adalah faktor eksposi (tegangan tabung 130 kv, arus tabung berkisar 59 – 128 mas). hasil penelitian didapatkan esd yang diterima berkisar 6,22-15,87 mgy, dosis yang diterima pasien pemeriksaan abdomen dipengaruhi arus tabung dan diameter abdomen serta esd yang diperoleh masih dalam batas yang ditetapkan bapeten sebesar 25 mgy. kata kunci : abdomen, ctdi, ct scan, esd, x – ray multimeter.

CT scan of the abdomen in adult patients is carried out to estimate the dose exposure received by the abdomen during the scanning process so that it does not exceed the dose limit set by BAPETEN. The purpose of this study was to determine the amount of ESD received by patients with abdominal examination at RSUDZA using CT-Scan and to find out whether the ESD received by patients with abdominal examinations using CT-Scan at the Radiology Installation of RSUDZA was in accordance with established standards. This study was conducted using X-Ray Multimeter and Ct Scan with the Siemens Somathom Emotion 128 slice, the number of patients in this study was 25 people, the measurement parameters used were the exposure factor (tube voltage 130 kV, tube current ranging from 59 - 128 mAs). The results showed that the ESD received ranged from 6.22 to 15.87 mGy, the dose received by patients with abdominal examinations was influenced by tube flow and abdominal diameter and the ESD obtained was still within the limits set by BAPETEN of 25 mGy.
