How did the CAT scan work?
During a CT scan, the patient lies on a bed that slowly moves through the gantry while the x-ray tube rotates around the patient, shooting narrow beams of x-rays through the body.
Instead of film, CT scanners use special digital x-ray detectors, which are located directly opposite the x-ray source..
How does electron beam CT work?
EBCT makes use of a stationary electron emitter which does not circle around the patient.
This electron emitter is large and partially surrounds the imaging circle.
An electron beam focus is swept electronically, not mechanically, as in conventional CT, along a tungsten target to emit X-rays from different angles..
What is EBCT used for?
Electron-beam computed tomography (EBCT) is a fast and sensitive test for detecting calcium build-up in the arteries of the heart.
It uses an electron gun instead of regular x-rays to scan the chest..
What is electron beam computed tomography primarily used for?
EBCT (ultrafast CT) is a highly sensitive technique to detect and quantify coronary artery calcification and has been used to triage patients presenting to the ED for chest pain.
Absence of coronary calcification is associated with a low 30-day risk of major cardiac events (\x26lt;1%)..
What is electron beam computed tomography?
Electron-beam CT (EBCT) is a fast, highly sensitive, and noninvasive technique to assess dynamic processes.
EBCT is also called ultrafast CT [32].
EBCT makes use of a stationary electron emitter which does not circle around the patient.
This electron emitter is large and partially surrounds the imaging circle..
What is electron beam tomography used for?
Definition.
Electron-beam computed tomography (EBCT) is a fast test to look for calcium build-up in the heart's arteries.
It uses an electron gun to scan the chest..
- EBCT makes use of a stationary electron emitter which does not circle around the patient.
This electron emitter is large and partially surrounds the imaging circle.
An electron beam focus is swept electronically, not mechanically, as in conventional CT, along a tungsten target to emit X-rays from different angles. - Electron-beam computed tomography (EBCT) is a fast and sensitive test for detecting calcium build-up in the arteries of the heart.
It uses an electron gun instead of regular x-rays to scan the chest. - So, the modern CT is typically an X-ray source and X-ray detectors mounted in an arc facing the source.
