Ultrasound phantom with solids mimicking cancerous tissue for needle breast biopsy

This study aimed at synthesizing hydrogels to simulate opaque breast tissue (BT) and coloured cancerous tissues (CT) different densities of the designed phantom improve biopsy-related skills along with ultrasonography. Both are tear-resistant therefore, can be trained multiple times in order lower price eye-hand coordination users. For this purpose, self-healing (SH) polyacrylamide (PAAm) (SH hydrogel) obtained by free-radical polymerization AAm, presence chemical cross-linker, BAAm, physical cross-linker stearyl methacrylate, C18, ammonium persulfate APS as initiator were used design phantoms. Psyllium was added BT differentiate density obtain human skin color it could distinguished from CT which also colored methyl violet. CTs characterized FTIR spectroscopy, mechanical, swelling, refractive index measurements. Designing phantoms ultrasonography, mechanical tests, observation needle track after biopsy, stabilization tests follow behaviours time. As a result study, self-healing, low-cost, suitable for multi-usage ultrasonographic biopsy successfully detected.
