Patient support for cone-beam computed tomography

Unmet NeedNewer imaging systems based on cone-beam CT (CBCT) introduces an additional design criterion for the head holder that has not been previously addressed. This invention results in a radiographic profile that avoids a well-known image artifact (shading and streaks in CBCT images commonly referred to as a “cone-beam artifact”).Technology OverviewThis...
