متن کاملAdjustable computerized stereotaxic brain atlas for transmission and emission tomography.
A computerized brain atlas adjustable to the patient's anatomy would serve serveral purposes. It could be used in stereotaxic surgery. Even more important would be its use in medical imaging to identify various brain structures, such as the basal ganglia and their nuclei, as well as individual cortical gyri. This atlas could be used for additional mapping of nonvisible structures in images obta...
متن کاملComputerized Ionospheric Tomography
ith the transition to the Global Positioning System, Transit has been decommissioned, after having served well for the Fleet. A new system, the Navy Ionospheric Monitoring System, was established using Transit satellites. This article examines the application of the new system to the field of computerized ionospheric tomography. (
متن کاملComparison between Needle Biopsy under Guide of Conventional Computerized Tomography (CCT) and Fluoroscopic Computerized Tomography (FCT) in Abdominal, Mediastinal, Lung, Pelvic, Bone, and Liver Masses
Background and Objective: Computerized tomography and fluoroscopic computerized tomography are amongst the methods used for guiding needle biopsy processes; however, fluoroscopic computerized tomography demonstrates the images during the process of biopsy. This study aims to compare and contrast the success of biopsy under guide...
