Compendium of Biomedical Instrumentation, 2019
Computed Tomography (CT) involves using an X-ray tube coupled to a detector system, encased within a doughnut shaped gantry. There is a separate table, on which the patient lies, that can move smoothly in and out of the gantry.

BIOIMPEDANCE TOMOGRAPHY (ELECTRICAL IMPEDANCE TOMOGRAPHY)
Annual Review of Biomedical Engineering, 2006Electrical impedance tomography (EIT) is a relatively new imaging method that has evolved over the past 20 years. It has the potential to be of great value in clinical diagnosis; however, EIT is a technically difficult problem to solve in terms of developing hardware for data capture and the algorithms to reconstruct the images.

Positron Emission Tomography/Computed Tomography
Seminars in Nuclear Medicine, 2008Accurate anatomical localization of functional abnormalities obtained with the use of positron emission tomography (PET) is known to be problematic. Although tracers such as (18)F-fluorodeoxyglucose ((18)F-FDG) visualize certain normal anatomical structures, the spatial resolution is generally inadequate for accurate anatomic localization of pathology.

Dental Clinics of North America, 1993
Although CT scanning has been available for less than 20 years, it has made a major impact on the practice of dentistry, particularly in oral and maxillofacial surgery, in the diagnosis and management of a wide variety of oral lesions. The use of computers to reconstruct x-ray attenuation data into an image allows the clinician to view pathology from ...

European Neurology, 2008
Lacunes consist of small vascular lesions with a volume of between 2 and about 30 mm. These lacunar infarctions are determined by an ischemia caused by obstructive diseases of small terminal vessels in the deep areas of the brain. While magnetic resonance currently appears to be a more sensitive diagnostic tool than computed tomography (CT) as far as ...

The machine whirs and clicks from slice to slice, as thetechnician watches through a shielded window and theimmobile patient moves on a pallet through a series ofstations. The mass of data from this exercise goes to afast computer and is integrated into detailed cross sec-tions in three dimensions.
