XCheck: Verifying Integrity of 3D Printed Patient-Specific Devices via Computing Tomography
(USENIX Security 2023) We designed a defense-in-depth approach to verify the integrity of 3D printed medical pastient-specific devices (PSDs). We leveraged CT scans to obtain physical characteristics of the prints, designed computer graphic techniques to crosscheck geometry, and computed Hounsfield units (HU) value distribution to validate materials.
