Abstract

One of the examinations in the radiology installation is the Shoulder Joint, where a sensitive organ close to the examination is the thyroid. If the thyroid organ absorbs too much radiation, it causes the effects of thyroid cancer and thyroid tumor. This research aims to determine how the dose received by the thyroid and whether the dose received exceeds the prescribed dose limit value. The type of research is a quantitative done at the installation radiology of Ibnu Sina Islamic Hospital Padang on 5 August 2021. The method is an experimental study, using ten samples with raysafe measuring instruments. Then the data is processed using the effective dose formula and displayed in tabular form. The results obtained in the form of absorbed dose are then converted into equivalent doses by switching the absorbed dose to the radiation weight factor. Furthermore, the equivalent dose is multiplied by the weight factor

Abstract

The collimator is a part of the x-ray device that has the function of regulating the size of the field. If this field is not aligned, the anatomy that should enter the irradiation field is not exposed to radiation. The large number of exposures performed can result in a mismatch between the area of the irradiation field and the X-ray beam produced. Distance variations are used to determine the suitability or value of the shift in the collimator field area tested. This study aims to determine the feasibility of a collimator on an X-ray plane by determining the similarity of the collimated beam with the X-ray beam.The type of research used is quantitative with experimental methods in the radiology installation of Andalas University Hospital Padang in August 2023 with variations of FFD 90 cm, 100 cm, 110 cm, and 120 cm. The measuring instrument used collimator test tool with collimation size 14x18 cm using small focal spot and large focal sp-axis (horizontal) and Y-axis (vertical) values by not exceeding 3% of FFD (ΔX + ΔY ≤ 3% of FFD).The test results of the collimator beam similarity test with FFD distance variations that comply with the tolerance limit ≤ 2% FFD are at FFD 100 cm, 110 cm, and 120 cm when using a small focal spot. While those that do not match or exceed the tolerance limit ≤ 2% FFD are FFD 90 cm small focal spot, FFD 90 cm, 100 cm, 110 cm, and 120 cm when using a large focal spot. Collimation that is feasible to use in the radiographic imaging process on a small focal spot with a distance (FFD) starting from 100 cm. The large focal spot is not feasible to use and needs to be improved.Keywords: Conformity test, Beam collimation, FFD distance variation

Abstract

Kontras adalah perbedaan densitas pada area yang berdekatan dalam radiograf. Semakin besar nilai kontras, maka gambaran akan semakin jelas terlihat. Salah satuuntukmeningkatkan hasil pencitraan radiograf, yaitu dengan membatasi luas lapangan lapangan kolimasi. Untuk itu perlu dilakukan penelitian tentang perbandingan kontras film pada luas lapangan berbeda. Penelitian ini bertujuan untuk mengetahui luas lapangan mana yang lebih baik digunakan untuk meningkatkan nilai kontras radiograf. Jenis penelitian kuantitatif dengan studi eksperimen dilakukan di Rumah Sakit Umum‘Aisyiyah Padang pada 07 Juli 2023, menggunakan alat stepwedge dan densitometer pada luas lapangan bervariasi.  Pengolahan data menggunakan rumus kontras yang harus mengetahui nilai densitas, kemudian data ditampilkan dalam bentuk tabel dan kurva. Hasil penelitian menunjukan bahwa nilai densitas yang paling tinggi diukur berdasarkan stepwedge adalah luas lapangan penyinaran yang kecil yaitu 15 cm X 15 cm yaitu nilai kontras nya 1,07. Sebab semakinkecil luas lapangan penyinaran, semakin sedikit radiasi hambur yang ditimbulkansehingga dapat meningkatkan densitas akan tetapi dapat menurunkan nilai kontras radiografi.
