Fabrication of a positional brain shift phantom through the utilization of the frozen intermediate hydrogel state

A novel CT-responsive hydrogel for the construction of an organ simulation phantom for the repeatability and stability study of radiomic features

“…The CT/PAA-Ca-Fe hydrogel and CT-HOSP not only show excellent feature stability and repeatability in radiomics, but also have good CT similarity and adjustability. At the same time, CT-HOSP breaks away from the application of traditional phantoms in surgical simulation, [48][49][50] expanding the new application of phantoms in the field of image analysis.…”
