Abstract

X-ray radiation plays a vital role in medical diagnostics but carries potential risks for both patients and healthcare workers. This study evaluates the effectiveness of cassava starch–based bioplastic combined with lead acetate as an absorber of radiation dose during femur radiographic examinations. The tests were performed using Anteroposterior (AP) and Lateral projections with both portrait and diagonal detector positions. Image processing applied the Gaussian High Pass Filter (GHPF) method at cut-off frequencies of 5, 10, and 15 Hz. Image quality was analyzed through Contrast to Noise Ratio (CNR) and Peak Signal to Noise Ratio (PSNR). Results showed that the use of bioplastic slightly decreased CNR and PSNR values compared to examinations without bioplastic; however, the quality remained within acceptable diagnostic standards. For example, in AP diagonal projection at 5 Hz, CNR reached 22.86 (with bioplastic) versus 21.95 (without), while PSNR values were 11.1 and 11.6, respectively. Increased Mean Square Error (MSE) values confirmed radiation attenuation, supporting effective shielding. Optimal image quality occurred at 5–10 Hz cut-offs, while 15 Hz produced misleading impressions of osteoporosis. Overall, lead-based bioplastic effectively reduces radiation dose while preserving diagnostic value, offering a safer and eco-friendly alternative in radiographic imaging.

Review

This study, "Reduksi Dosis Radiasi Pemeriksaan Femur dengan Bioplastik Timbal: Pendekatan Citra dan Anatomi," addresses a critical concern in medical imaging: the reduction of X-ray radiation dose for both patients and healthcare workers. The authors propose an innovative and environmentally conscious solution by evaluating the effectiveness of a cassava starch-based bioplastic combined with lead acetate as a radiation absorber during femur radiographic examinations. This approach is commendable for its dual focus on safety and sustainability, offering a promising alternative to traditional shielding materials. The methodology involved comprehensive testing using Anteroposterior (AP) and Lateral projections, incorporating both portrait and diagonal detector positions. Image processing was rigorously applied using the Gaussian High Pass Filter (GHPF) method at various cut-off frequencies (5, 10, and 15 Hz), and image quality was quantitatively assessed via Contrast to Noise Ratio (CNR) and Peak Signal to Noise Ratio (PSNR). While the bioplastic's use resulted in a slight reduction of CNR and PSNR values compared to unshielded examinations, the crucial finding is that image quality consistently remained within acceptable diagnostic standards. The increase in Mean Square Error (MSE) values further corroborates the bioplastic's radiation attenuation capabilities. The identification of optimal image quality at 5–10 Hz cut-offs and the warning regarding misleading impressions of osteoporosis at 15 Hz demonstrate a thorough analysis of the image processing parameters. Overall, the findings strongly support the potential of this lead-based bioplastic to effectively reduce radiation dose without compromising the diagnostic value of femur radiographs. This represents a significant step towards safer and more eco-friendly practices in radiographic imaging. While the abstract presents compelling evidence for the bioplastic's efficacy in an experimental setup, future research could benefit from quantifying the precise dose reduction and exploring *in vivo* studies to validate its performance in clinical settings. The study lays an excellent foundation for further development and potential clinical implementation of this novel shielding material.
