Dynamic cerebral perfusion CT (PCT) is an effective imaging technique for the clinical diagnosis and therapy guidance of many kinds cerebrovascular diseases (CVDs), but large radiation dose imposed on a patient during repeated scans greatly limits its applications. Achieving low-dose PCT with help advanced satisfactory methods needed. A kinetic-induced voxel-clustering filter (KVCF) proposed in this work to process noisy distorted images acquired from scan protocols. In new method, intrinsic...
The diagnostic impact of deep learning computed tomography (CT) reconstruction on intracranial aneurysm (IA) remains unclear.
Abstract Background: Prosthesis design of hip joint and computer-assisted surgical planning can benefit from segmentation-based computed tomography (CT). Purpose: To automatically segment the three-dimensional (3D) images, authors developed a deep learning-based segmentation algorithm verified its feasibility with CT image joint. Methods: Conventional augmentation strategies specific strategies, which were designed to mimic deformed shape blurring boundaries diseased hips, applied obtain...
Objective To investigate the effect of Karl iterative reconstruction on CT image quality enhancement. Methods ① Phantom study: A 120 kVp/140 mAs tube current was set as standard radiation dose. Low-dose setting is implemented with a 50% reduction, i.e., 70 mAs, whereas voltage to kVp. Two experimental groups algorithms filtered back projection(FBP) and reconstruction(with noise reduction 1–9 levels) were compared. The power spectrum(NPS) deviation metrics adopted assess degree. ②...
Abstract Objective To explore the effect of motion correction in quantifying pericoronary adipose tissue (PCAT) coronary CT angiography (CCTA). Methods Forty patients who underwent CCTA were retrospectively enrolled this study. Two series reconstructed without (MC) and with correction. The image qualities evaluated using a five-point Likert scale rating system. right artery (RCA) PCAT segmented. Volume RCA, volume fat attenuation index (FAI) calculated compared paired sample t-test between...
