An inverse‐geometry volumetric CT system with a large‐area scanned source: A feasibility study

We propose an inverse‐geometry volumetric CT system for acquiring a 15‐cm volume in one rotation with negligible cone‐beam artifacts. The system uses a large‐area scanned source and a smaller detector array. This note describes two feasibility investigations. The first examines data sufficiency in the transverse planes. The second predicts the signal‐to‐noise ratio (SNR) compared to a conventional scanner. Results showed sufficient sampling of...
