Computed tomography (CT) has evolved into a powerful diagnostic tool, and it is impossible
to imagine current clinical practice without CT imaging. Because of its widespread …

Until recently, cardiovascular computed tomography angiography (CCTA) was associated
with considerable radiation doses. The introduction of tube current modulation and …

Purpose: Spectral/multienergy CT has the potential to distinguish different materials by K‐
edge characteristics. K‐edge imaging involves the two energy bins on both sides of a K …

Objective: We explore the feasibility of principal component analysis (PCA) as a form of
spectral imaging in photon-counting CT. Methods: Using the data acquired by a prototype …

Computed tomography (CT) is a non-invasive X-ray diagnostic technique that allows
reconstructing cross sections of a patient׳ s body, providing detailed information about …

基于光子计数探测器的能谱CT, 可以同时采集多个能谱通道的投影数据, 并获得相应能量范围内
物质的吸收特征, 可以有效应用于物质识别与材料分解. 主成分分析是一种很好的多元数据分析 …

High-resolution micro-CT offers 3D non-destructive imaging but scan times are prohibitively
large in many cases. Advancements in image reconstruction offer great reduction in number …

Abstract Since Hounsfield's Nobel Prize winning breakthrough decades ago, X-ray CT has
been widely applied in the clinical and preclinical applications-producing a huge number of …

Objective. Cone-beam CT (CBCT) in modern pre-clinical small-animal radiation research
platforms provides volumetric images for image guidance and experiment planning …

Experiments were performed to evaluate the energy-discriminative performance of a
spectral (multi-energy) micro-CT system. The system, designed by MARS (Medipix All …
