WebNov 1, 2024 · Embedded with CT reconstruction, this framework naturally encapsulates the physical imaging model of CT systems and is easy to be extended to deal with other challenges. This work is helpful to push the application of the state-of-the-art deep learning techniques in the field of CT. Figures WebMar 7, 2013 · In a CT scan, multiple x-ray images are taken from different directions. The x-ray data are then fed into a tomographic reconstruction program to be processed by a computer. The deduction of the tissue structure from the x-rays is done using a technique first obtained in 1917 by Johann Radon.
WebWe proposed that CT scan with coronal reconstruction (CTCR) improves the detection of small DIs missed by chest x-ray (CXR) and CT scan with axial views (CTAX). We … WebSep 22, 2024 · While Computed Tomography (CT) is necessary for clinical diagnosis, ionizing radiation in the imaging process induces irreversible injury, thereby driving researchers to study sparse-view CT reconstruction. Iterative models are proposed to alleviate the appeared artifacts in sparse-view CT images, but their computational cost is …
WebSep 1, 2015 · BACKGROUND AND PURPOSE: Radiation dose in temporal bone CT imaging can be high due to the requirement of high spatial resolution. In this study, we assessed whether CT imaging of the temporal bone by using an ultra-high-resolution scan mode combined with iterative reconstruction provides higher spatial resolution and … WebApr 7, 2024 · Brief Summary: A deep learning-based de-noising (DLD) reconstruction algorithm (ClariCT.AI) has the potential to reduce image noise and improve image quality. This capability of the CliriCT.AI program might enable dose reduction for contrast-enhanced liver CT examination.
WebSep 21, 2024 · Computed tomography (CT) reconstruction from X-ray projections acquired within a limited angle range is challenging, especially when the angle range is extremely small. Both analytical and iterative models need more projections for effective modeling.
WebMar 23, 2024 · High-resolution CT (HRCT) of the chest, also referred to as HRCT chest or HRCT of the lungs, refers to a CT technique in which thin-slice chest images are obtained and post-processed in a high-spatial-frequency reconstruction algorithm.This technique obtains images with exquisite lung detail, which are ideal for the assessment of diffuse … shared home contents insuranceWebSep 24, 2016 · Image reconstruction is the term describing the calculation of images from the raw data obtained from the detector modules of the CT scanner.
