Background: This study aims to determine the procedures, techniques, reasons and evaluation of 3D conformal radiotherapy of squamous cell carcinoma case in the orbital region with additional bolus that has been done in the Radiotherapy unit of Dr. Sardjito Yogyakarta Hospital. In addition, from this research also to find out how the visually tumor response to the radiation that has been given and there are limits of research for tumor responses made observations from the beginning of radiation to the completion of radiation.Methods: This type of research is qualitative with a case study approach. The data was collected in November-December 2017 at radiotherapy Unit of Dr. Sardjito Yogyakarta Hospital by observation methodology, interview with Radiation Oncologist Specialist, Medical Physicist and Radiographer. the data obtained from the study were analyzed by an interactive model, creating the interview transcripts subsequently reduced and processed within the type of open coding, given within the type of quotations then are often drawn conclusions.Results: The results showed that the 3D Conformal Radiotherapy of squamous cell carcinoma case on orbital region with the addition of a bolus in Dr. Sardjito Yogyakarta Hospital consists of a CT Simulator examination, TPS (Treatment Planning System), Verification and Treatment (radiation therapy). The bolus in the treatment process is intended for this case to provide a 95% dose to the target tumor raised up to the surface. For the response shown in this case the patient was not good despite the reduction in tumor, the tumor response was not good (response 50%) according to WHO criteria showed stable disease criteria (SD).Conclusion: 3D conformal radiotherapy of squamous cell carcinoma case in the orbital region of this patient with the addition of a bolus aims to obtain a homogeneous distribution of all tumor targets and for visual tumor response in this case according to WHO criteria showing stable disease (SD) criteria.

Background:Radiation exposure rate measurements have been done on the MSCT 64 Slices examination room radiology section Dr. Moewardi Surakarta Hospital due to lack of repeat measurement after replacement of examination door. This study aims to determine the rate of radiation exposure and radiation safety in the examination room for workers and public refers to the NCRP report no. 147 about stuctural shielding design for medical x-ray imaging facilities. Methods: This type of research is quantitative research with survey approach. This research was conducted in March 2018. Data collection was done by observation, documentation, and measure the radiation exposure in measurement points some places, which are controlled and uncontrolled areas. Data analysis was done descriptively by comparing data with NCRP report no.147. Results:The measurement results of the rate of radiation exposure, point A and B shows the leakage of radiation exposure. While the point of C, D, E no leakage of radiation. Conclusions: The value of background radiation exposure in the MSCT 64 Slices examination room radiology section Dr. Moewardi Surakarta Hospital exceeds the dose rate base on the height of the location according to UNSCEAR. Leakage of radiation exposure occuring at point A is woorkes door and point B front door MSCT 64 Slices examination room not safe for workes and public because it exceeds the limit of radiation exposure rate value which allowed

PENERAPAN PENJAMINAN MUTU RADIOLOGI PADA KENDALI MUTU PERALATAN BUCKY GRID PESAWAT DIGITAL RADIOGRAPHY Diana Wahyusyafitri; Gatot Murti Wibowo

The research about grid performance testing in Radiology Installation RA Kartini Jepara have been done using X-ray digital radiography type Multix Select DR. X-ray digital radiography hasn’t been re-tested after acceptance testing in 2016. Based the frequency, it’s often use. The purpose of this study to know the implementation of radiology quality assurance and quality control and to determine the result testing. Research conducted in the examination room in radiology installation RA Kartini Jepara with depth interviews, two radiographers as a respondents. Then, put a Grid Allignment Test Tool in the middle of center beam, with vertical rays. Afterthat, all the holes exposed by a factor using 45 kVp and mAs setting 1 and 5. Then do the processing and measure the optical density using densitometer three times each holes. In the analysis of data from measurement should determine the value of highest density on the 3rd or center hole and getting decreases to the lateral. The result show the quality assurance and quality control aren’t going well because there is none about QA Committe. Density measurement data show, on the first hole has 2,48 and 2,56. On the second hole has 2,66 and 2,74. On the third hole has 2,71 and 2,81. On the fourth hole has 2,69 and 2,72. The fifth hole has 2,71 and 2,78. The first hole show lowest density value and getting decreases to the lateral side. It means bucky is missalignment with central rays.
