Abstract

The purpose of this study was to determine the rejection of digital image analysis procedure CR softcopy hereinafter referred to as RFA, and describe the profile and characteristics of the proportion image rejection (rejection rates) based on the operational conditions of CR.Quantitative research was conducted with the observational approach. Data were collected by random sampling from 1181 digital image system CR-1137 type 1 at A hospital and the total number of CR type 2 digital image at B hospital on the status of post-image processing. Profiles and characteristics of the CR-system rejection rate was 9.15% while the type 1 for type 2 CR-system is 4.57%. Largest percentage of CR image rejection on both failitas dominated by chest radiographic anatomy of the organ which is 69.44% (A) and 48.08% (B). The findings reject rates of 15.87% due to poor performance of x-ray equipment and distribution teridenfitikasinya reject rates based on radiographer in A hospital deserves special attention. Though the radiographer and the employment rate figures reject individually in “ A” hospital not correlated (0.67 more than p-value).

Abstract

The examination of intravenous pyelography (IVP) is one of the tests carried out with the aim to examine abnormalities of urinary tract anatomy and physiology. The opacity of urinary tract anatomy and function of the kidney, especially on an X-ray, is influenced by serum urea and creatinine levels of the patients prior to conducting the IVP examination. The study was an observational survey with retrospective approach. Purpose of this study was to describe the opacity of kidney picture in Nephrogram phase with different urea and creatinine levels. Urea and creatinine data were obtained from medical records of patients who underwent radiological examinations in Dr. Moewardi Hospital in 2013. The nephrogram phase imaging picture was taken from the document of Computed Radiography. The study sample was 41 patients. Data of overview kidney opacity in nephrogram phase were analyzed with Matlab software to get the value at the point calyces Pixel kidney (ROI). Research results revealed that 32 p atients (78%) of 41 patients had laboratory results of urea levels higher than normal (8-25 mg/100 ml) and 34 patients (83%) had normal creatinine levels (0.6 to 1.2 mg/ 100 ml). The results of test matlab found that opacity kidney picture nephrogram phase in patients with urea level higher than normal had a decrease of Pixel value (65220 pix.value) when compared to patients with normal urea levels (65231 pix. values ). Patients with creatinine above 1.2 mg/ 100 ml had a higher Pixel value (65239 pix.value), comparing to patients with normal creatinine levels (65219 pix.value). Further research is expected to gain more understanding. It is recommended that patients' levels of urea and creatinine should be checked in 48-72 hours before the time of IVP test, and interventions to decrease these levels should be implemented before conducting the test.

Abstract

This study aims to determine adequacy of thick protective lead aprons as radiation in Radiology Services Unit in Semarang. This research is quantitative with observational approach radiation measurements. The samples were hospitals in Kota Semarang. The independent variable is the thickness of the lead apron and the dependent variable in this study is the radiation behind the lead apron. Data analysis was performed using descriptive statistics to take a conclusion. The results showed Adequacy lead apron at the Semarang Hospital, HVL values between 4 to 7 HVL or dose rate are forwarded after passing through the apron of 6.25% to 0, 781%. Value adequacy thick lead apron 0.5 mmPb that used had a value below the threshold set by Bapeten that dose forwarded after passing the lead apron is less than or 0,02 μSv which means lead apron can be used for radiation safety assurance in hospital and radiology departement units in the Semarang.

Abstract

This study aims to describe wheter or not the patients' chest x-ray in hospital over Semarang are already has an appropriate radiation dose. This quantitative study was conducted with descriptive analysis. Data were collected by random sampling technique. The method in the measurement of patient dose was using Thermoluminesensi Dosimean meter (TLD) which is placed at the central point (CP). Profile picture over of chest radiation dose in adult patients to the 1st hospital was an average of 0.2139 mGy , 0.0758 mGy in 2nd hospital, and 0.3548 mGy in 3rd hospital . From the overall sample, the average adult chest x-ray dose was 0.1731 mGy. From these data it is concluded that the dose was still below the reference dose (0.4 mGy) , but the application of radiation protection programs and quality control diagnostic tool should still be on the run.
