CBCT-subsystem performance of the multi-modality Brightview XCT system (M09-26)
Nuclear Science Symposium Conference Record（2009）
摘要
The new Brightview XCT system uses a flat-panel detector to perform CBCT imaging for attenuation correction and localization. Features include a small footprint due to an offset-detector geometry, advanced scatter correction - both software and hardware - isotropic voxels, and GPU-accelerated reconstruction. System performance characteristics of the CBCT system such as spatial resolution, HU linearity, uniformity, noise, low-contrast detectability, and dose measurements are discussed in this paper.
