sound waves or radiotracers. Computed tomography (CT) scans use ionizing radiation, or x-rays, to get an image of the inside of the body. Your doctor might order a CT scan if they believe you have a broken bone or if they are trying to detect tumors or other signs of illness in the...
Generally 3D CT image is reconstructed from data scanned by multi-row or panel detector.But most of high energy industrial CT systems used in non-destructive testing are based on line-array detectors.Helical fan beam scan or multilayer fan beam scan can be used to obtain the data for 3D CT...
We can compute the DCT of a input scan image dx,y of size M × N, by using the expression as defined in Eq. 1. For all values of u = 0, 1, 2 …, M−1 and v = 0, 1, 2, …, N − 1 expression of Eq. 1 must be evaluated. Also, given Du,v, ...

CT scan of the brain, if specialised treatment is indicated. Undertriage of elderly patients may cause a selection bias, as we excluded secondarily admitted patients. This could result in an underestimation of time to CT scan because time to CT could be longer in elderly with diffuse symptoms....
The automatic registration algorithms were found to have sub-voxel levels of accuracy, with transmission scan-based CT-PET registration more accurate than emission scan-based registration of the phantom images. Respiration induced image artifacts were not found to influence registration accuracy while ...

As a result medical image analysis approaches and statistical tools have been explored during the last 15 years to identify different tissue states. Differentiating and spatially localizing dead and salvageable tissue, predicting the final ischemic tissue outcome, and understanding factors that influence ...
We applied the framework developed in this work to personalize six patient-specific coronary hemodynamics models (Fig.1). An overview of the framework is provided in Fig.2. The framework starts with image-based anatomical models for the coronary arteries and the left ventricle (LV) that were re...
d CT scan and ctDNA detection for patient P072. Full size image Serial ctDNA monitoring for personalized dynamic recurrence risk prediction When evaluating the longitudinal changes of VAFs of detected ctDNA mutations in serial plasma samples during disease surveillance, we observed a correlative trend...
