Abstract

The mathematical model represents the human organ such as the urinary bladder,spine, intestine, and organs in the pelvic. This study aimed to evaluate the 2D pelvic model created using mathematical methods. Forty-seven computed tomography (CT) images underwent abdomen-pelvis (at level L3 spine to pubic symphysis) CT examination were simulated. The profile and intensity values of phantom images and reference images were evaluated by ImageJ. Visual inspection was assessed by three independent specialists at least 3 years of experience. The image processing including image filters, image segmentation, and image
reconstruction, were also examined. The results revealed that the profile graphs of pelvic phantom and referenced CT images were similar. The comparison of the intensity value of the muscle (p = 0.085) and the organ (p = 0.972) were not significantly different. The visual inspection score was moderate similarity equal to 1.68 (p = 0.015). In conclusion, the simulated phantoms can be processed by medical image processing algorithms and could be developed to use in further research works.
