Computer assisted tomography in orbital disease.
Computer assisted tomography (CAT) in the transverse axial plane, a fundamentally new method of x-ray diagnosis, was developed from I967 to 1972 by G. N. Hounsfield (I973) at the Central Research Laboratories of E.M.I. Ltd. Clinical evaluation of this technique by J. Ambrose (I973) at Atkinson Morley's Hospital has indicated the enormous value of the investigation in patients with intracranial ...
متن کاملAn AI Approach to Computer Assisted Tomography
Computer assisted tomography (CAT) systems demand large amounts of time and space. In this paper, we describe an approach to solving the CAT problem using several AI techniques including representation selection and pruning. Rather than backproject intensity data onto a pixel grid or voxel lattice, we solve the problem geometrically -a backprojection region is stored as a convex polygon in a pl...
متن کاملStress Analysis of the Human Ligamentous Lumber Spine-From Computer-Assisted Tomography to Finite Element Analysis
Detailed investigation on biomechanics of a complex structure such as the human lumbar spine requires the use of advanced computer-based technique for both the geometrical reconstruction and the stress analysis. In the present study, the computer-assisted tomography (CAT) and finite element method (FEM) are merged to perform detailed three dimensional nonlinear analysis of the human ligamentous...

Computer assisted instruction during quarantine and computer vision syndrome
Computer vision syndrome (CVS) is a set of visual, ocular, and musculoskeletal symptoms that result from long-term computer use. These symptoms include eyestrain, dry eyes, burning, pain, redness, blurred vision, etc, which increase with the duration of computer use. Currently, with the closure of schools and universities due to the continued COVID19 pandemic many universities have taken the pr...
