Abstract

The use of X-rays cannot be separated from the radiation given to the patient's body, therefore the radiation exposure received by patients should be very low according to the ALARA principle (As Low As Reasonably Achieveable). The research method is a quantitative description by using themeasurement method radiation output as a reference for the estimated radiation dose received by the patient, then the analysis of the success of socialization to radiographers about DRL as an optimization effort in radiographic examination. The results of the radiation dose estimation using themethod radiation output by determining theequation power function of themeasurement radiation output where the value of the radiation dose rate increases as the kVp value increases with y= 0.0005x2.9242. From theresults, it was pre-test found that the number of correct answers was 120 and 84 wrong, with a percentage of 59% and the number of respondents 10.03 people. Meanwhile, for theresults, the post-test number of correct answers was 194 and 12 wrong, with a percentage of 94% and the number of respondents being 15.98 people. It is hoped that radiographers can apply the principle of optimization in carrying out all radiographic examinations.

Abstract

Higher education is responsible for producing graduates who are globally competitive with hard skills and soft skills, one of which is by doing internships, therefore it is necessary to analyze the learning objectives of student internships at the Department of Radiodiagnostic and Radiotherapy, Health Polytechnic of the Ministry of Health Jakarta II to maintain the quality of graduates according to the Indonesian National Qualification Framework. Data collection was carried out on students who were doing their 1st internship in 7 hospitals in the DKI Jakarta area. The data used by giving students pre and post-tests on the understanding of apprenticeship learning, then surveying the number of radiographic examinations that have been carried out by students by the understanding of apprenticeship learning at the hospital. Analysis of decision making based on the understanding of the 1st apprenticeship learning if the pre and post-test percentage value> 50% and analysis of the number of radiographic examinations carried out by students as an indicator for evaluating the understanding of apprenticeship learning. and the post-test percentage value of 70.1% of students can carry out radiographic examinations, with a comparison of the post-test results there is an increase of 12.6% in the learning objectives of the apprenticeship and 31.2% in supporting data information about a clinical experience during the internship, from the pre and post-test> 50%, the understanding of apprenticeship learning has been achieved. Then in analyzing the number of radiographic examinations carried out by students as an indicator of evaluating understanding of apprenticeship learning, it is hoped that the college can evaluate the placement of student hospitals during the internship so that radiographic examinations that have not been fulfilled during the internship can be fulfilled during the following round of internships

Abstract

Awareness and perception have become a public health and environmental problem for at least the last two decades, so public awareness and understanding of knowledge about natural radiation and radiation protection efforts are needed. The method by providing understanding is carried out by counseling using posters and interactive lectures, accompanied by the provision of pre-post test questionnaires to measure residents' understanding of radiation and the protection efforts that can be done. Then the data obtained will be tested using SPSS 26 to find out whether there is a change in understanding after providing counseling to residents with the Wilcoxon test. The results after the community knowledge counseling increased by 92% for indicators of understanding, utilization, and effects of radiation, while 97% for indicators of radiation protection with antioxidants. From the results of the Wilcoxon test, the p value < 0.001 therefore it can be said that counseling activities about radiation and protection efforts can affect the level of understanding of the residents.

Abstract

Effort reducing the severity of COVID-19, a flattening of the curve is needed which aims to prepare the treatment system so that the capacity of the hospital can treat patients and provide health care workers, to meet the minimum standard of radiological services during the pandemic, therefore necessary planning and control of radiology services to patients. This research is quantitative descriptive by analyzing the data and discussing the literature, the research was conducted in March-June 2020 in the department radiology of the COVID-19 Emergency Hospital in Wisma Atlet Kemayoran. Subjects of the study were department radiology readiness: facilities radiology, equipment, and conditions of workers, analysis of radiological services, as well as radiation protection and safety for workers and patients. Results for radiology facilities and equipment are very adequate in carrying out radiographic examinations, workers equipped with PPE according to standard operating procedures for handling COVID-19, Radiology services based on workload indicator staff need (WISN) analysis required 16 radiographers with an estimated number of chest radiograph examinations of 4000 patients, and 1 medical physicist. In applying for radiation protection, we must pay attention to the principles of distance, time, and shielding.

Abstract

CT number is one of the indicators in determining the diagnosis of disease, so it is necessary to ensure the level of accuracy. The aim is to determine the parameters of kilovoltage and tube current to the CT value. Descriptive quantitative analytic research method with previously tested linearity and the suitability of the CT number. Furthermore, the variation of kilovoltage: 80kVp, 100kVp, 140kVp and the tube current value is 192mAs. After that, the tube current variation was continued: 80mAs, 100mAs, 140mAs and the voltage value was 120kVp. Phantom image results were analyzed using radiant viewer software with a region of interest (ROI) size of 5mm. Then analyze the correlation coefficient to determine the degree of relationship between the kilovoltage and milliampere-second parameters to the CT number. The results of the linearity test and the suitability of the CT number value were within the tolerance limit. For variations in kilovoltage to CT number , the correlation coefficient values ​​are water R2=0.09, fat R2=1, soft tissue R2=0.9, bone R2=0.7. As for the milliampere-second variation of the CT number , the correlation coefficient values ​​are: water R2=0.7, fat R2=0.8 , soft tissue R2=1, bone R2=0.7.

Abstract

A contrast thorax CT scan is a CT scan procedure in the chest area (thorax) that uses a contrast agent to improve visualization of organs and structures in the chest. Lung tumors are the growth of abnormal lumps in lung tissue which can be benign or malignant. Awareness of the potential and increasing radiation dose in all CT scan examinations encourages radiographers to want and be able to minimize radiation exposure as the main goal in radiological examinations and also strive for radiation protection during examinations. CT scan radiation dose accounts for 70% of the total dose received from medical imaging. High or low doses of radiation received can increase the risk of cancer. The large dose of radiation received by a patient during a CT scan, therefore regulations are needed that will guarantee monitoring of the radiation dose received by the patient to ensure that the dose received is commensurate with medical purposes. The radiation dose to the patient needs to be optimized by applying the Diagnostic Reference Level (DRL) to optimize medical exposure protection for the patient. Dosage evaluation in clinical contrast chest CT scan examinations for lung tumors and the application of DRL in these examinations have never been carried out at RS X Jakarta. Objective: This study aims to determine the DRL value in clinical contrast thorax CT scan examination of lung tumors at RS CTDIvol and DLP values from clinical contrast Thorax CT Scan examination of lung tumors. The DRL value is calculated at Quartile 3 (75 percentile) using the descriptive frequency test and Wilcoxon test in the SPSS application, then compared with the latest IDRL value. Results: Quartile 3 value (75 percentile) from CTDIvol and DLP CT scan chest contrast clinical lung tumors, namely The CTDIvol value was 12.55 mGy and the DLP was 439 mGy.cm. Conclusion: The DRL value in the clinical contrast thorax CT scan for lung tumors at Hospital X Jakarta. is still below the recommended standard, which shows that the radiation output dose in this examination practice is within normal limits and is classified as safe
