This study addresses the crucial role of Magnetic Resonance Imaging (MRI) of the head in detecting disorders of the trigeminal nerve, particularly trigeminal neuralgia. Trigeminal neuralgia can significantly affect quality of life and is commonly observed in the elderly. However, some hospitals face limitations due to the absence of image fusion features in their MRI modalities, highlighting the need for practical alternative solutions.This study proposes the development of a MATLAB-based image fusion application as a practical alternative. The use of this application is expected to enhance visualization of the trigeminal nerve and surrounding blood vessels, particularly in hospitals whose MRI devices lack integrated image fusion capabilities. A mixed-methods approach was employed, combining qualitative analysis to describe the implementation process of image fusion using MATLAB, and quantitative analysis to compare the results with those from built-in fusion software on MRI machines.This study successfully implemented image fusion techniques using MATLAB on raw data obtained from CISS 3D and 3D TOF sequences, with a focus on visualizing the trigeminal nerve. The comparison between the fused images generated using MATLAB and those produced by the MRI system's built-in fusion software revealed significant differences. The MATLAB-based image fusion technique demonstrated a substantial contribution to improved understanding and diagnosis in medical practice, particularly in merging images from different MRI modalities. Thus, MATLAB-based fusion can be considered a relevant and progressive solution, especially for hospitals lacking access to advanced fusion technology.

Background: Abdominal radiography examination is one of the examinations that is often carried out and contains radiosensitive organs, namely the gonads. Milli Ampere Second (mAs) is one of the parameters regulated in making radiographs besides kV. mAs is the product of mA and s and there are often variations in the use of mA and s values to produce the same mAs value. This study's objective was to identifythe difference in radiation dose values for the surface of the gonad skin on anteroposterior abdominal radiographs with changes in different combinations of mA and s values.sMethods: This is pre-experimental quantitative research. The research object is body phantom. Data were collected by exposing abdomen radiography the body phantom and measured the amount of radiation dose to the skin surface of the gonad. mA and s setting : 160 mA 125 ms; 200 mA 100 ms; dan 250 mA 80 ms. Data analysis was carried out using statistical tests.Results: The average radiation dose to the skin surface of the gonad organs in the combination is 160 mA 125 ms; 200 mA 100 ms; and 250 mA 80 ms, namely 883.27 ÂµGy; 883.09 ÂµGy; and 883.72 ÂµGy. Statistical test results show there is no significant difference between the combination of 160 mA 125 ms; 200 mA 100 ms; and 250 mA 80 ms, namely 883.27 ÂµGy; 883.09 ÂµGy with a significance of 0.748 (p-value > 0.05). mAs determine the intensity of X-rays; the number of X-rays produced is proportional to milliamperes. As long as the mAs value remains constant, the amount of radiation intensity produced is the same, and the radiation dose is sameConclusions: There is no significant difference in the value of radiation dose to the skin surface of the gonad area on abdominal radiography with different combinations of mA and s values at the same mAs value

Panoramic dental radiography uses X-rays to produce radiographs of the jaw and facial structures, from the teeth to the TMJ and the entire dental arch. Exposure to X-rays during an examination can be problematic because sensitive areas such as the thyroid gland and eyes adjacent to tooth structure also receive radiation exposure. Patients in panoramic examinations do not use eye radiation protection equipment for the orbit, namely Pb glasses, while the eyes are close to the dental arch which can receive radiation exposure, so eye radiation protection equipment is needed in panoramic examinations for patient safety. The aim of the research is to determine the function test and performance test of the Eye Radiation Protection Device.This type of research is quantitative research with an experimental approach. The research sample was 3 patients with variations of 3 kV: 70, 76, and 86 kV with a setting of 10 mA. The radiation dose to the eye was measured using a phantom and pocket dosimeter before and after using the radiation protection design tool, then looking for the average, difference and percentage and carrying out the Kruskal-Wallis spss test.The results of the three radiographs showed no artifacts, the exposure factor before using the device was 70 kV = 0.08 mSv, 76 kV = 0.17, 86 kV = 0.27 mSv while the radiation dose received after using the device with an exposure factor of 70 kV = 0 mSv, 76 kV = 0.86 kV = 0.003 mSv, while from the Kruskall-walls statistical test pre-test and post test kV 70 shows a significant value of 0.034 <0.05, kV 76 does not show a significant value of 0.121 > 0.05, kV 86 shows a significant value of 0.043 <0.05. The design of this eye radiation protection device has succeeded in reducing or reducing the radiation dose around the eyes by up to 100%. Meanwhile, the level of feasibility of the tool has a respondent score of 80%. Suggestions for using a thermoluminescence radiation measuring instrument (TLD) with smaller units, namely ÂµSv.

CT scanning is a medical imaging technique that allows detailed visualization of structures within the body using X-ray radiation. The pixel intensity in the image is interpreted in Hounsfield Units (HU), which measure the relative density of tissue compared to water. WW and WL are two important parameters in adjusting the visualization of CT scan images, allowing radiologists to optimize the display of various tissue structures. WW is the middle value of the selected HU range. This value determines the grayscale intensity that is the center of the image contrast range. WL in tissue with a certain density, such as distinguishing between brain tissue and lesions or edema. The purpose of this study is to optimize the use of parameters to improve image quality and diagnostic accuracy and determine the optimal WW and WL. This research supports secondary transformation in the health care system, in improving the quality of clinical services through innovation in diagnostic technology.This research is an experimental study. Direct measurements were made of variations in 10 window width values and 3 window level values. After data collection, three radiologists assessed the data using a questionnaire. A kappa test was performed to assess the agreement or similarity of observer perceptions in assessing the questionnaire. Data analysis was performed using the Kolmogorov-Sprinov test to determine the appropriate test. The normality test yielded a p-value > 0.05, indicating that the data were normally distributed.The Kappa test results of 0.82 with p <0.001 indicate that there is a very good level of agreement or agreement between observers in assessing the quality of CT Scan images. The Kolmogorov-Smirnov results show that the data distribution is normal with a p value = 0.120 (p > 0.05), thus fulfilling the requirements for parametric testing. The results of the Paired T-Test show differences in image quality between WW and WL. Window Width at 95 with Window Level 35 is proven to provide the most optimal image quality and produces the highest score (mean = 4.5). And shows better contrast between the area ofbleeding and normal brain tissue, so that bleeding can be clearly identified. The clarity of brain anatomy is also better seen compared to wider or narrower WW variations. In addition, the noise level is relatively low, so it does not interfere with the radiologist's interpretation in assessing the image.
