Abstract

Background: A conductive medium on ultrasound is a medium that is used to obtain sound wave transmission by minimizing air between the transducer and the skin. This study used materials that are easily found such as gel wax and paraffin for making the gel pad. A good oil and mineral based wax gel are used as a basic ingredient for ultrasound gel making. Gel pad can be used to minimize the structure of unauthorized organs. One of which is the shoulder. Objective: This study aims to determine the quality of the image in the use of standard gel, and the use of gel pad as a medium for ultrasound shoulder. Method: Gel pad is made by mixing gel wax and paraffin ingredients. This gel is used to obtain images from ultrasound investigation. The study used 16 samples with a total of 64 images obtained in which 32 images using standard gel and gel pad in the long axis position and 32 images using standard gel and gel pad in the short axis position. The analysis of image results is done using matlab image processing to assess SNR. The image quality obtained from the results of the questionnaire was assessed by a specialist in radiology. Image quality processing based on SNR was tested using independent T test. Meanwhile, the results of image quality from the questionnaire assessment were tested using Wilcoxon. Result: As many as 64 objects were obtained using standard gel. The gel pad showed that there were significant differences in the results of image quality based on SNR values. In the results of the questionnaire assessment, there are several anatomic organs that have no significant differences. Conclusion: The use of standard gel was still higher compared to the use of gel pad. The gel pad is able to become a standard gel alternative on ultrasound shoulder examination.

Abstract

Background: Radiography examinations are the most widely used and indispensable tools in medical imaging. The dose received by the patient should be known to prevent the risk of radiation exposure. Patient dose in radiography examination can be best estimated in terms of entrance surface dose (ESD). ESD value can be obtained by using the recorded dose viewer installed on the device. However,  not all devices have this feature. Other methods can be conducted using thermoluminescence dosimeter (TLD) although it practically requires a high cost. Purpose: The study aims to estimate the ESD as a dose profile for patients undergoing radiography examination using tube output. Method: The patient data and exposure factors were retrospectively recorded for 263 patients. The ESD was estimated from the measurements of the X-ray tube output and recorded exposure factors.  Results: The ESD value varied from 0.002 to 0.41 mGy. In the thorax PA, thorax LAT, cervical LAT, cervical AP, skull AP, skull LAT, genu LAT and waters was found (0,23±0.05) mGy, (0,09±0,05) mGy, (0,07±0,04) mGy, (0,13±0,08) mGy, (0,03±0,01) mGy, (0,06±0,02) mGy, (0,04±0,00) mGy (0,04±0,02) mGy, respectively. These results were further used to determine the Local Diagnostic Reference Level (LDRL) value. Conclusion:  The results revealed that LDRL fell below the national DRL value and international reference

Abstract

Background: Radiographers are responsible for producing image quality which can provide accurate diagnostic information by considering the lowest possible radiation dose according to the As Low As Reasonably Achievable (ALARA) principle. Participation between radiographers and medical physicists is needed in optimizing efforts to control the selection of exposure factors by the required clinical radiographic examination. Purpose: To analyze the exposure index on examination chest posterior-anterior. Methods: Quantitative descriptive by analyzing the percentage of exposure index results used in chest PA radiographs as an effort to optimize: image quality and radiation dose indicators on chest PA examinations. Results: Optimization of exposure percentage results of 68%, 25% underexposure, 4% underexposure, 2% overexposure, 1% overexposure (noise). Radiographers have tried to optimize: image quality and image radiation dose by selecting exposure factors that are tailored to the patient’s condition and maximizing post-processing for increased quality. Conclusion: In optimizing the CR imaging system, it is necessary to understand exposure index, this is related to the underexposed, optimal, and overexposed categories, besides radiographers can take advantage of post-processing to improve image quality.

Abstract

Background: Adaptive Statistical Iterative Reconstruction (ASIR) reconstruction in unenhanced abdominal CT scan reduce the radiation dose from 11.6 mSv to 2.07 mSv. However, the decrease in dose is accompanied by a decrease in image quality. Signal to Noise Ratio (SNR) is one of image quality parameters. Purpose: This study aims to determine the effect of the ASIR method on the optimal Signal to Noise Ratio (SNR) value in unenhanced abdominal CT of urolithiasis in clinical data. Method: 27 samples collected and the SNR was measured on the ASIR reconstruction results at the level of 40%, 50%, 60% by placing the ROI  in organ structures with different densities. Result: The results of this study indicate that the ASIR method has a significant effect on the SNR value. Based on the linear regression test, the value was 0.005 ( p< 0.05) and only had an effect of 9.5% on SNR. Conclusion: It can be concluded that the ASIR method affects the optimal SNR value for unenhanced abdominal CT on urolithiasis. The ASIR 60% level was recommended.
