The AAPM, through its members, meetings, and its flagship journal Medical Physics, has
played an important role in the development and growth of x‐ray tomography in the last 50 …

Use of cone‐beam computed tomography (CBCT) is becoming more frequent. For proper
reconstruction, the geometry of the CBCT systems must be known. While the system can be …

A table‐top volumetric CT system has been implemented that is able to image a 5‐cm‐thick
volume in one circular scan with no cone‐beam artifacts. The prototype inverse‐geometry …

Purpose: This paper presents an overview of multisource inverse‐geometry computed
tomography (IGCT) as well as the development of a gantry‐based research prototype …

Purpose: In general, there is a reciprocal relationship between the width and flux from an x-
ray focal spot (corresponding to spatial resolution and photon noise), so that large focal …

An inverse‐geometry computed tomography (IGCT) system uses a large source array
opposite a smaller detector array. A previously described IGCT reconstruction algorithm …

Inverse geometry computed tomography (IGCT) is a new type of volumetric CT geometry that
employs a large array of x‐ray sources opposite a smaller detector array. Volumetric …

This study introduces and evaluates respiratory-correlated four-dimensional (4D) inverse
geometry computed tomography (IGCT). The projection data of the IGCT were acquired in a …

Accurate and artifact-free reconstruction of tomographic images requires precise knowledge
of the imaging system geometry. A projection matrix-based calibration method to enable C …

This study investigates the feasibility of obtaining CT-derived 3D surfaces from data
provided by the scanning-beam digital x-ray (SBDX) system. Simulated SBDX short-scan …
