Background: Based on riskesdas data in 2013, the prevalence of cancer in Indonesia reached 1.4% or around 347,792 people. The technique used at Kensaras Hospital for the use of Electalinac for IMRT engineering and Linac Siemens for 3D engineering with energies of 5 mV, 7 mV, 8 mV, 10 mV, 12 mV, 14 mV. Radiotherapy simulation using the GE 16 slice CT Simulator with adequate space, thermoplast masks, individual blocks and universal blocks, and bolus. Constraints that occur in the use of blocks for Siemens linac which still use manual blocks do not use MLC.Methods: Research analysis using SRL PICO method seeks clinical information in scientific evidence-based health science practices. The results of literature search show that the goal of radiotherapy is to provide the maximum radiation needed to kill cancer, while the minimum to the surrounding healthy tissue.Results: The static MLC method is a method in which the MLC moves to form a segment when the radiation stops and MLC stops as long as the radiation lasts for each gantry angle and MLC stops for radiation and so on for each gantry angle. Meanwhile, the kensaras hospital for Linac Siemens still uses a manual block made from a chimney and is attached to the linacgantry which is prone to falling and having to replace the block every corner. Conclusion: Radiation therapy with a linear electron accelerator is experiencing rapid development and is a cancer therapy that is relatively inexpensive and does not provide radioactive waste. The use of MLC is safer and can move to form segments when radiation stops and MLC stops during radiation for each angle of the gantry.

Multi Slice Computed Tomography is a diagnostic imaging method that can display cross section anatomy in the axial, sagital, and coronal areas. MSCT Stonography imaging both visualizes the anatomy of the urinary tract and stone pathology supported by the presence of ureter tracking techniques and without using contrast media. On this method, the appropriate window width will produce an optimal anatomical picture. The Study aims to determine the effect of window width on anatomical image information on MSCT Stonography.Type of research is quantitative experimental approach, conducted in January-February 2020 in Hasan Sadikin Bandung hospital, Bandung. Research with variations in window width 300 HU, 350 HU, 400 HU, 450 HU, and 500 HU on MSCT stonography og 10 patients. Criteria’s patients is patients with clinical kidney stones, willing to be a research sample. Result imagery rated two respondents, include parenchymal kidney, pelvic calices kidney, ureters, vesica urinary, and stones kidney. Then do Kappa test continued testing Friedman to know the highest mean rank and the influence og the window width oh the image og MSCT stonography.Based on the result of the Friedman statistical test overall anatomy obtained significance value (p-value) = 0.000 0.05 means that there is an influence of window width value, the contrast resolution will increase and the better the firm boundary, but the resulting image will be more radioluscent. Based on Friedman’s mean rank test result obtained the highest mean rank of 3,54 in a variation of window width 300. The most optical window displays anatomy information using window width 300.

The clinical role of radiotherapy in oncology, where ionising radiation is applied to damage the deoxyribonucleic acid (DNA) structure of tumour target cells in order to halt uncontrolled cell proliferation. The success of radiotherapy is influenced by patient compliance in completing the entire course of treatment according to the prescribed schedule. Consequently, the aim of this study was to develop a digital radiation card model using an Android-based smartphone for patients undergoing external radiation therapy at Murni Teguh General Hospital in Medan, with a view to improving patient compliance and satisfaction. This study employed a Research and Development (R&D) approach to develop an Android-based digital radiation card and assess its feasibility. The R&D method was chosen as it is suitable for research that produces a product whilst simultaneously conducting testing and refinement prior to wider implementation. The ADDIE development model was utilised, comprising five stages: Analysis, Design, Development, Implementation, and Evaluation. Based on the expert validation test, the digital radiotherapy card has been found to be effective in improving patient compliance and satisfaction in the radiotherapy department. The effectiveness of using Android-based digital radiation cards for patients undergoing external radiation therapy in improving patient satisfaction is demonstrated by the results of the Wilcoxon test, which show that all items relating to satisfaction have a p-value < 0.05; this indicates a significant difference between pre-test and post-test scores for satisfaction following the implementation of the Android-based digital radiation cards. The effectiveness of using Android-based digital radiation cards for patients undergoing external radiation therapy in improving patient compliance was demonstrated by the results of the Wilcoxon test, which showed that all items relating to compliance had a p-value < 0.05. Consequently, the use of digital radiation cards can be deemed effective in improving respondents’ compliance.
