This assignment examines the possibility of 3D printing a structure that would be visible with ultrasound waves. The purpose of this research is to implement it with pessary rings used for POP (Pelvic Organ Prolapse) syndrome patients, as examining the patients could then be done more efficiently. Currently, fitting the ring creates problems for a significant number of patients, but the causes of those problems cannot be easily identified.
In order to address this issue, 3D-printed structures at different print settings are investigated with the goal of finding a combination that reflects the ultrasound wave back onto the transducer. The difference in the images produced by different structures (normally those are body tissues) comes from several factors, among which are acoustic impedance, acoustic intensity, and attenuation. In this assignment, creating such a structure will be attempted by examining the impedances of the 3D printed materials with the aim of receiving a signal of higher amplitude at the probe, as well as identifying the ring with a greater amount of detail.
