摘要: An anthropomorphic phantom is a radiologically accurate, tissue realistic model of the human body that can be used for research into innovative imaging and interventional techniques, education simulation calibration medical equipment. Currently available CT phantoms are appropriate tools equipment but have major disadvantages educational simulation. They expensive, lacking appearance characteristics anatomical organs when visualized during X-ray based image scanning. In addition, not modular hence users able to remove specific from inside or training purposes. 3D printing technology has evolved print anatomically accurate abdominal mannequin address limitations existing phantoms. this study, images clinical patient were following organ shells: liver, kidneys, spleen, large small intestines. fatty was made using modelling beeswax musculature modeled liquid urethane rubber match radiological density real in Hounsfield Units at 120kVp. Similarly, all printed shells filled with an agar-based solution mimic The scope applications various aspects education, allowing us key areas importance without need scanning patients.
