Within transplate-and-rotate CT machines, a complete linear movement of the gantry across the object being scanned occurs during the imaging process.  

An electronic system employed to introduce frequency filtering into the video circuits, offering a range of attenuation curves and responses. This filtering technique is recognized for its ability to provide precise measurement of the average value of a designated image area, minimizing noise and enabling clear visualization of large areas with low density. Additionally, it…

The achievable visual clarity of a matrixed scan image across the two-dimensional area of the CRT (Cathode Ray Tube).  

A phrase used to describe the preloaded software installed on a computer that encompasses all facets of device functionality.  

In the course of a rotational scan, where the x-ray source orbits around the patient, a particular cross section of the patient’s body comes under the influence of the x-ray paths. This cross section represents the region through which the x-rays pass during the scan. The thickness of this section, commonly referred to as the…

The duration during which the patient is exposed to the primary X-ray beam with an open shutter is referred to as the scan time. The selection of the scan speed governs the precise length of this interval.  

The generation of a CT image necessitates a specific mechanical motion. In numerous machines, a single scan has the capability to yield two distinct images.  

The mean deviation, which represents the average or arithmetic mean of the absolute differences from a fixed value, disregards the signs of the deviations. In the context of a specified material, the mean deviation is expressed as CT number(s) relative to a standard or fixed value, known as the CT number of the reference material.…

In a capacitor, when the resistance declines below its typical value, it results in the occurrence of excessive leakage current.  

General term used for various types of magnetic recording disks used through-out the system. Specific types or uses are designated by a descriptive name such as system disk or floppy disk. Also see floppy disk.
