Background, Motivation and Objective During neurosurgery, intraoperative imaging can serve to provide feedback on cerebrovascular hemodynamics and help monitor procedures such as the placement of flowdiverting stents near an aneurysm. Ultrasound can potentially play a major role here given its real-time scanning capability. However, its proper use is known to require extensive user training, and to do so it would be beneficial to create phantoms that can be leveraged as emulation tools for operator skills development. As such, we have sought to devise a novel framework for fabricating ultrasound-compatible cerebral aneurysm phantoms based on patient-specific vascular information.
