Abstract

This research aimed to determine the Compliance test of MSCT Philips 128 Slice generator and X-ray tube performance at Mangusada Hospital in accordance with the tolerance limits based on the BAPETEN Head Regulation of the Republic Indonesia Number 2 of 2022 so that it can be stated that the generator and X-ray performance is in reliable condition. In this research, Raysafe Xi CT and Raysafe Xi R/F were used to measure the output value of radiation dose, tube voltage and HVL thickness on MSCT Philips 128 Slice by carrying out four test activities, namely radiation output reproducibility test, radiation output linearity test,  test, and X-ray beam quality test. The performance test of the generator and X-ray tube has been carried out on MSCT Philips 128 Slice with obtained Coefficient of Variation (CV) value in the radiation output reproducibility test of 0.00278, Coefficient of Linearity (CL) value in the radiation output linearity test of 0.00882,   at a tube voltage of 80 kVp is 6.30280 mGy/100mAs,  at a tube voltage of 120 kVp is 19.59800 mGy/100mAs,  at a tube voltage of 130 kVp is 24.48431 mGy/100mAs, and the HVL thickness at a tube voltage of 120 kVp is 8.79 mmAl. This result show that the performance MSCT Philips 128 Slice generator and X-ray tube in reliable condition.

Abstract

This study focuses on evaluating the quality and performance of the digital mammography system at Mangusada Badung Regional Hospital (RSD) in an effort to prevent and early detect breast cancer. With the prevalence and mortality rate of breast cancer continuing to increase, early detection is important. Digital mammography has an important role in this early detection. This study aims to evaluate the performance of digital mammography at Radiology Installation Mangusada Badung through a series of tests. generator and x-ray tube suitability test and automatic exposure control (AEC). The results showed conformity tests on voltage accuracy (maximum error 0.8%), linearity (CL 0.01), reproducibility (radiation output CV 0.001, peak voltage CV 0.003), emergency timer (stops at 0 mAs), tracking (% patient thickness % exposure index error 7.9%, voltage exposure index error 6%), AEC (voltage CV 0.000, current time CV 0.000), exposure time (large focus t 0.87 seconds, small focus t 1.21 seconds). The test results show that the digital mammography system meets the conformity test criteria in accordance with PERKA BAPETEN no. 2 of 2022. This provides confidence that the device meets the established quality standards. With this fulfillment, it is expected that the accuracy of diagnosis can be improved and the risk of errors in early detection of breast cancer can be reduced. Therefore, the digital mammography system at RSD Mangusada Badung is expected to be.
