Dual source hybrid spectral micro-CT using an energy-integrating and a photon-counting detector.
(Physics in medicine and biology, 2020-10-21)Preclinical micro-CT provides a hotbed in which to develop new imaging technologies, including spectral CT using photon counting detector (PCD) technology. Spectral imaging using PCDs promises to expand x-ray CT as a functional ... -
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 ... -
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, ... -
Impaired formation of beta-adrenergic receptor-nucleotide regulatory protein complexes in pseudohypoparathyroidism.
(J Clin Invest, 1984-05)Decreased activity of the guanine nucleotide regulatory protein (N) of the adenylate cyclase system is present in cell membranes of some patients with pseudohypoparathyrodism (PHP-Ia) whereas others have normal activity ... -
Micro-CT imaging of multiple K-edge elements using GaAs and CdTe photon counting detectors.
(Physics in medicine and biology, 2023-04)Objective.To evaluate the performance of two photon-counting (PC) detectors based on different detector materials, gallium arsenide (GaAs) and cadmium telluride (CdTe), for PC micro-CT imaging of phantoms with multiple contrast ... -
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 ...
