Background : Suitability test for light collimation are tests to ensure that x-ray aircraft meet radiation safety requirements and provide precise and accurate diagnostic or diagnostic information. Suitability test for light collimation is carried out on x-ray aircraft at Al-Islam Bandung Politeknik.Methods: The research method used in quantitative experimental method. The suitability test was carried out with a collimator test tool and beam alignment test tool placed on the tape then performed an experiment using an exposure factor of 75 Kv, 200 mA and 8 mAs with FFD 100 cm.Results: Based on the tests that have been carried out, it is known that there is a discrepancy in the width of the collimation beam. The large discrepancy between the light field area and the radiation field area, that is, the edge X₁ 0.3 cm, the edge X₂ 0.5 cm, the edge Y₁ 0.5 cm, the edge Y₂ 0.1 cm. So the value of ∆X is 0.8% FFD, the value of ∆Y is 0.6% FFD, and the value of ∆X + ∆Y is 1.4% FFD. While the deviation of the central point is less or right than 3⁰. These results indicate that the discrepancy in the width of the light beam collimation and center point deviations is still within the tolerance limits.Conclusions: There is a discrepancy between the X-ray light field and the collimated light field, but it is still within the limit of the test value to the passing value of the predefined test.

X-ray radiation in the medical field offers substantial diagnostic benefits but also poses potential risks to both patients and medical personnel. This study aims to evaluate the effectiveness of bioplastic made from cassava starch and lead acetate as a radiation dose absorber in femur radiographic examinations. The examinations were conducted using Anteroposterior (AP) and Lateral projections with portrait and diagonal detector positions. Image processing utilized the Gaussian High Pass Filter (GHPF) method with cut-off frequencies of 5, 10, and 15 Hz. Image analysis was performed using Contrast to Noise Ratio (CNR) and Peak Signal to Noise Ratio (PSNR). The results indicated that the use of bioplastic reduced CNR and PSNR values compared to examinations without bioplastic, although the image quality remained within acceptable clinical limits. For instance, in the AP diagonal projection with a 5 Hz cut-off, the CNR value for the proximal femur was 22.86 (with bioplastic) versus 21.95 (without bioplastic), while the corresponding PSNR values were 11.1 and 11.6, respectively. Additionally, radiation dose attenuation was supported by increased Mean Squared Error (MSE) values, indicating effective shielding by the bioplastic. Cut-off frequencies of 5 and 10 yielded the best image quality in both conditions.

Multislice Computed Tomography (MSCT) stenography is one of the preferred modalities for evaluating urolithiasis due to its high diagnostic accuracy. However, the increasing use of CT imaging has raised concerns regarding patient radiation exposure. This study aims to evaluate the radiation dose received by patients undergoing MSCT stenography at Dr. Hasan Sadikin General Hospital, Bandung, and to assess the influence of technical parameters on dose variability. This is a quantitative descriptive study using a cross-sectional approach. A total of 40 adult patients (male and female) who underwent MSCT stenography were selected as samples. Radiation dose data, including CTDIvol and DLP, were collected directly from the CT console and supported by patients’ medical records. Multiple linear regression analysis was performed to assess the relationship between CT dose and technical parameters such as kV, mAs, scan range, and volume of focus (VOF). The research showed that the average CTDIvol was 11.83 mGy and the average DLP was 644.64 mGy·cm, both of which exceeded the international Diagnostic Reference Levels (DRLs). Statistical analysis showed that only the mAs parameter had a significant effect on CTDIvol (p = 0.043), while other parameters such as kV, scan range, and VOF showed no significant influence.
