Abstract

Pemanfaatan Computed Radiography (CR) membuat Radiografer menjadi kurang memperhatikan dalam pemilihan faktor eksposi. Sehingga sering terjadi eksposi berlebihan (overexposure) yang membuat pasien menerima dosis radiasi berlebih dan eksposi kurang (underexposure) yang akan menimbulkan noise walaupun sudah dilakukan post-processing. Penelitian ini bertujuan untuk mendapatkan nilai faktor eksposi yang optimum pada pemeriksaan radiografi kepala dengan menggunakan metode 15% kVp Rule of Thumb. Penelitian ini dilakukan di Laboratorium Jurusan Teknik Radiodiagnostik dan Radioterapi pada bulan Maret – Mei 2020, menggunakan metode kuantitatif eksperimental dan observasi terhadap nilai dosis paparan dan kualitas citra pada penggunaan faktor eksposi dengan metode 15% kVp Rule of Thumb : 42 kV 128 mAs, 50 kV 64 mAs, 60 kV 32 mAs, 72 kV 16 mAs, 82 kV 8 mAs, 94 kV 4 mAs, 108 kV 2 mAs menggunakan phantom pada pemeriksaan radiografi kepala proyeksi AP. Hasil penelitian Variasi faktor eksposi metode 15% kVp Rule of Thumb pada pemeriksaan kepala proyeksi AP mempengaruhi nilai sensitivity, dosis paparan, dan kualitas citra, dimana nilai sensitivity yang direkomendasikan memiliki nilai noise paling rendah pada sampel 60 kV 32 mAs dan 72 kV 16 mAs. Pengaturan faktor eksposi yang optimum dapat menggunakan nilai rentang kV sebesar 60 – 72 dan mAs dalam rentang 16 – 32 yang menghasilkan nilai sensitivity dalam kategori properly exposed dengan nilai dosis dan noise dalam jumlah minimal pada pemeriksaan radiografi kepala proyeksi AP.

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

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

Iterative reconstruction can optimize radiation dose and improve image quality on CT scan. This research method is quantitative analytic with the analysis of the results of the head CT examination parameters associated with image quality to changes in variations of 80 kV, 100 kV, 120 kV with the use of iterative reconstruction. Image quality measurements are the Hounsfield Unit (HU) value, standard deviation, and Signal to Noise Ratio (SNR) using Radiant Viewers. Effective dose measurement using the Dose Length Product (DLP). Then perform the Kruskal Wallis test to determine the difference in the SNR value to tube tension and Iterative Reconstruction using IBM SPSS version 24. The image quality results of the HU value increase due to changes in the kV value, but the value does not change significantly when the iDose changes, for standard deviation experiences decrease due to changes in kV, but the value of the value does not experience a significant change at the time of change in iDose, while SNR increases due to changes in kV value and changes in iDose. The percentage ratio of the effective dose in the use of standard kV with 80 kV decreased radiation dose by 62%, while at 100 kV there was a decrease of 25%, and the use of 120 kV experienced an increase of 25%. The results of the Kruskal Wallis test p-value <0.001, therefore it can be concluded that there is a difference in the SNR image quality at each change in iDose and kV parameters.
