Photon-counting cine-cardiac CT in the mouse.
(PloS one, 2019-01)
The maturation of photon-counting detector (PCD) technology promises to enhance routine CT imaging applications with high-fidelity spectral information. In this paper, we demonstrate the power of this synergy and ...
Spectral diffusion: an algorithm for robust material decomposition of spectral CT data.
(Phys Med Biol, 2014-11-07)
Clinical successes with dual energy CT, aggressive development of energy discriminating x-ray detectors, and novel, target-specific, nanoparticle contrast agents promise to establish spectral CT as a powerful functional ...
Spectrotemporal CT data acquisition and reconstruction at low dose.
(Med Phys, 2015-11)
PURPOSE: X-ray computed tomography (CT) is widely used, both clinically and preclinically, for fast, high-resolution anatomic imaging; however, compelling opportunities exist to expand its use in functional imaging applications. ...
Dual-energy micro-CT functional imaging of primary lung cancer in mice using gold and iodine nanoparticle contrast agents: a validation study.
(PLoS One, 2014)
PURPOSE: To provide additional functional information for tumor characterization, we investigated the use of dual-energy computed tomography for imaging murine lung tumors. Tumor blood volume and vascular permeability were ...
A neural network-based method for spectral distortion correction in photon counting x-ray CT.
(Physics in medicine and biology, 2016-08)
Spectral CT using a photon counting x-ray detector (PCXD) shows great potential for measuring material composition based on energy dependent x-ray attenuation. Spectral CT is especially suited for imaging with K-edge contrast ...
Hybrid spectral CT reconstruction.
(PLoS One, 2017)
Current photon counting x-ray detector (PCD) technology faces limitations associated with spectral fidelity and photon starvation. One strategy for addressing these limitations is to supplement PCD data with high-resolution, ...
