Semiconductor detectors that directly measure the electrical signals produced by X-rays have hugely improved the resolution and contrast of computed tomography scanners. In the 1970s computed ...
Ultrahigh-resolution (UHR) photon-counting detector (PCD)-CT demonstrated more than 90% accuracy in detecting coronary in-stent restenosis (ISR), outperforming standard-resolution reconstructions, ...
(c) Photon count statistics reconstructed from the distributions of pulse rising-edge time at different effective mean photon number ranging from 0.05 to 5. The measured photon count statistics (color ...
Photonova Spectra i is the first in the next generation of spectral photon counting CT systems with 8-bins of energy resolution, powered by GE HealthCare’s proprietary Deep Silicon detector technology ...
Compared with energy-integrating CT (EICT), ultrahigh-resolution (UHR) photon-counting CT (PCCT) enhanced the visualisation of small vascular structures in aortic imaging while reducing radiation ...
In a prospective imaging study of 200 adults with lung cancer, photon-counting CT reduced radiation exposure, yielded fewer adverse reactions and provided higher image quality and better detection of ...
