Radon Transform (RT) becomes a mathematical basis for solving computerized tomography, and finds application in medical imaging image processing. Finite groups represent digital images; the (FRAT) is then applied. To overcome periodization effect of finite transform, Do Vetterli [1] introduce novel ordering FRAT coefficients. This paper introduced detailed analysis optimal coefficients that int...
Objectives To determine whether real-time passive notification of patient radiation exposure via a computerized physician order entry system would alter the number of computed tomography scans ordered by physicians in the Emergency Department (ED) setting. Methods When a practitioner ordered a computed tomography scan, a passive notification was immediately and prominently displayed via the c...
We introduce the concept of computerized tomographic microscopy in magnetic resonance imaging using the magnetic fields and field gradients from a ferromagnetic probe. We investigate a configuration where a two-dimensional sample is under the influence of a large static polarizing field, a small perpendicular radio-frequency field, and a magnetic field from a ferromagnetic sphere. We demonstrat...
