Abstract

This study was aimed to determine the difference of the effective dose from the clinical and theoretical on the head CT-Scan examination of adult patients and compare the data with the permitted dose limit from BAPETEN. The data collected at Haji Hospital Surabaya using MSCT Siemens Somatom Definition AS 64 Slice on five adult patients, aged between 28-67 years old. The step before the scanning process were adjusting the voltage (kV) and current values (mA) on the CT-Scan. The scanning duration for each patient was 4s and resulted in head images with CTDIvol and DLP values displayed on the monitor screen. The effective dose limit value for the head CT scan was 2.8 mSv, according to BAPETEN. The study results showed that the effective dose on head CT Scan examination was below the safe dose limit value, while the different fractions between the clinical and theoretical of Patient A, B, C, D, and E was 4.11%; 5.46%; 6.19%; 6.52%; and 5.42%, respectively.

Abstract

The quality of the contrast enhancement, which is deemed to be vague in contrast between one region and another, is a problem that many doctors face once identifying their patients with CT scan images. Image correction was used in this study to help doctors gain good CT scan images. In addition to reducing errors in the administering of radiation doses during treatment, accurate images are used to locate and assess the extent of cancer in patients. In this study, a computer application program to improve image contrast was created using the linear regression equation method. In this investigation, the cancer area is still being manually marked by doctors. Additionally, the proportion of the cancer area in the image that the doctor marked from the corrected image is calculated by comparing the ratio of cancer pixels to body pixels. The severity of the cancer is estimated using the proportion of the affected area. The error percentage for the average improvement in application performance is 0.15689%.

Abstract

A dental x-ray is an x-ray used for checking teeth. During the inspection process, the patient will receive the dose resulting from the function of the formation of x-rays. To know the magnitude of the dose, the radiation measurement tool required, and any instances of the hospital do not have it. To see the magnitude of the dose, a radiation measurement tool was needed. In many cases, the hospital did not have it, so the hospital had to borrow instruments to measure the radiation. With these problems, the purpose of this research is to know the value exposed parameters and can calculate the weight of the absorbed dose without the use of tools to measure the radiation. Using the equation of exposure then, it can calculate exposed parameters and then know the absorbed dose received by the patients teeth. This research was conducted with fifteen tools and dental x-rays with various merk and types. The fifteen tools will have a value of expose parameters that is different because it depends on the voltage waveform, the filtration, and the beam size used. This research is done by placing the proper dose measurement tools under the CONUS cylinder. The radiation measurement tool will connect to the computer with ocean applications that read the dose number. In the process expose, wich in the set is expose time. The greater the time hence, the larger the dose also accepted. And obtained a value of expose parameters minimum of 2,109, while the value tells parameters maximum of 21,937.
