Background: Radiological examination in cervical services, Radiographers often opening the collimation wider of the size of the imaging plate for fear of being cut. This is done because it is supported by the image cropping facility on the CR. So there is a habit of opening the collimation width as wide as the imaging plate, which is often done with the assumption that it is better to widen the collimation than cut off the object. Obviously this will increase the radiation dose in patients with basic limitations. According to ICRP, patient safety must refer to the principle of radiation protection ALARA namely in the shortest possible time to get quality radiographs and patients receive the most minimum radiation exposure as possible.Methods: This research is a descriptive analytic research conducted with a cross sectional approach. The study was conducted by varying the radiation field area to be used for cervical examination. There are 10 variations of collimation area with 3 (three) exposures in each collimation. Then measured contrast, noise and radiation dose. Radiation dose is calculated by means of a babyline device.Results: The results showed that the collimation setting did not affect contrast radiography in CR because collimation was not the main factor that could affect contrast radiography on CR. The collimation setting on cervical radiography has an effect on the radiation dose, so it is necessary to adjust the collimation to get the minimum dose possible. The most optimal collimation area on cervical radiographic examination was obtained at a size of 12 x 24 cm with the smallest noise reception and dose compared to others and had higher contrast. Average contrast value achieved was 0.45 with a dose of 39.23 µGy.Conclusion: The collimation setting on cervical radiography has an effect on the radiation dose, so it is very necessary to adjust the collimation to get the minimum dose possible. The most optimal collimation area on cervical radiographic examination is obtained at a size of 12 x 24 cm with the smallest noise reception and dose compared to others and has a higher contrast.

Backgroud: The research of performance test of MRI machines were done by doing performance test of nine different parameters in three hospitals in the province of Bali, where in two of these three hospitals are having troubled MRI machines which directly affected the image quality and therefore this research is also aimed to find out the performance of MRI machines in some hospitals in the province of Bali and intended as a baseline data if there will another test.Methods: This research is a quantitative study with survey approach. The tools and materials for this research were three MRI machines, which was consisted of two 1,5 Tesla machines and a 0,3 Tesla machine, phantom ACR, and MRI head coil. The data were collected by doing nine MRI performance testing procedures with ACR (2015) as a guideline and then the data were analyzed using international standards issued by ACR (2015).Results: Visual checklist test result of all the hospitals get 12 pass every day from the first day to the twentieth day. SNR test in Badung Regional General Hospital obtain measurement results of 268.17 and in The Board Of Tabanan General Hospital at 15.78 and at Sanglah Central General Hospital of 2.4. To test the artifact analysis only in The Board Of Tabanan General Hospital only found one type of artifact is the artifact geometric distortion. In testing the high contrast resolution in Sanglah Central General Hospital and Badung Regional General Hospital get the same result, namely insert a separate resolution of up to a third group, and the The Board Of Tabanan General Hospital insert a separate resolution to the second group. The test results in low contrast resolution Sanglah Central General Hospital and Badung Regional General Hospital get the same result, namely that there are 10 spokes are visible, then the The Board Of Tabanan General Hospital number of spokes that appear are 9 spokes. In testing the slice thickness accuracy in Sanglah Central General Hospital get the standard deviation of measurement of 5.12mm and in Badung Regional General Hospital get the standard deviation and the measurement of 0.64mm in The Board Of Tabanan General Hospital get the standard deviation of measurement of 0.48mm. Results of the geometric accuracy test in The Board Of Tabanan General Hospital has a difference measurement of 4.2mm X axis, Y-axis of 1.3mm, and has no difference in the Z-axis, in Badung Regional General Hospital has a difference of X-axis measurement of -3.1mm, have no difference in the Y axis the Z axis of 2mm, in Sanglah Central General Hospital has a difference measurement of 1.36mm X axis, Y-axis and Z-axis of 0.39mm for -3.53mm. The test results slice position accuracy in Sanglah Central General Hospital get the standard deviation measurements for -1.33mm, in The Board Of Tabanan General Hospital of 0.85mm, and in Badung Regional General Hospital of -0.3mm. For the test setup and table position accuracy throughout the hospital to get the same measurement is 5mm.Conclusion: Out of nine parameters in the test : only four parameters, which were high contrast resolution test, low contrast resolution test, slice position accuracy test, and setup and table position accuracy test, that met the international standards in all hospitals, whereas all the hospital didn’t meet the international standards in geometric accuracy test. There were two hospitals that didn’t meet the international standards in signal to noise ratio test, while one hospital didn’t meet the standards in artifact analysis test and slice thickness accuracy test.

Background: Malignancy of lung cancer is the biggest cause of pleural effusion. To diagnose lung cancer pleural effusion, a thorax MSCT can be examined. The MSCT parameter that affects image contrast is window width. The purpose of this study was to determine the differences in the anatomical information of thorax MSCT images in the post contrast mediastinal window to the use of window width range 350-600 HU values in cases of lung cancer pleural effusion, and to determine the appropriate window width value to obtain optimal anatomic image information on Thorax MSCT in cases of lung cancer pleural effusion.Methods: This type of research is quasi experimental. The research was conducted at the Radiology Installation of the Dr. Moewardi Hospital. The data were 60 images of the post contrast mediastinal window thorax MSCT axial slice from 10 patients with 6 window width variations (350 HU, 400 HU, 450 HU, 500 HU, 550 HU, 600 HU). An image assessment was conducted by 3 respondents regarding the resulting of 5 anatomical information. Data analysis used Friedman statistical test.Results: The results showed that there was a difference in the anatomical information of the thorax MSCT in the post contrast mediastinal window to the window width variation in cases of lung cancer pleural effusion with a significance level of p value 0,000 (ρ 0.05). Differences in anatomical image information occur in the anatomy of the aorta, limits of pleural effusion with lesions and clarity of lesions, where as there is no difference in anatomy of the right and left primary bronchus. The optimal use of the window width value for thorax MSCT in the post contrast mediastinal window cases of lung cancer pleural effusion is WW 350 HU with a rank value of 4.61.Conclusions: This study shows that the use of 350 HU window width produces better anatomical image information than the use of other window widths in the case of pleural effusion of lung cancer.

Background: In Indonesia, nasopharyngeal cancer ranks 4th most in malignancies. As a method of treatment, the development of radiotherapy has made it possible to give high doses to tumors with little risk of healthy tissue, but still maintain accuracy by performing geometry verification procedures. The purpose of this study was to determine the geometry verification procedure of nasopharyngeal cancer with EPID on the Linac plane in RSUP Dr. Kariadi Semarang; the average geometric shift that occurs and why is only done before fractions 1 and 4 only.Methods: This type of research is qualitative with a case study approach. The data is taken from February 2019 to June 2019 by the method of observation, documentation and interviews. The data obtained were analyzed by interactive models, making transcripts of interviews then reduced and processed in the form of open coding, presented in the form of quotations and concluded.Results: The results showed that the geometry verification procedure was started by making a calendar treatment, adjusting the patient's setup at the origin point, switching to the iso center point. Take the image portal with EPID AP and Lateral projections. Match image portals with DRR images. Then the geometric shift data were obtained with a mean shift from the iso center in 5 patient samples: vertical axis 0.15 cm to superior; longitudinal -0.01 cm anteriorly and laterally 0.04 cm to the right. Tolerance limit of 0.3 cm. This verification is only done before fractions 1 and 4 because of the high service load.Conclusion: The geometry verification procedure has been going well with the results of the shift is still below the tolerance limit. Verification information before the 1st and 4th fractions was not enough to assess the accuracy of the irradiation carried out properly maintained.
