Contrast sensitivity is a major characteristic that determines what tissues and body structures are XRay Image Formation and Contrast. Learning Objectives. References and Resources. Mind Map Summary.
Learning Objectives While looking at a radiograph define image (radiographic) contrast and describe how it is expressed. The formation of a CT image is a distinct three phase process. The scanning phase produces data, but not an image. The reconstruction phase processes the acquired data and forms a digital image. The visible and displayed analog image (shades of gray) is produced by the digitalto analog conversion phase. There are adjustable factors Factors affecting contrast in an xray image include the tube output, or the kVp.
This is a measure of the energy of the xray beam leaving the xray tube and passing through the patient to form an image. Chapter 20 Radiology and Diagnostic Imaging; Xray technique used to contrast a detailed cross section, at a predetermined depth, of a tissue structure.

Published: 23rd March, The purpose of the Compton effect is to reduce as much contrast on the xray image. factors in xray production. Similar to the five ways an xray can interact with matter, only two are important to the formation: the Compton The xray photons are released in a beam with a range of energies (xray spectrum) out of the window of the tube and form the basis for xray image formation Formation of ghost images due to metal objects on the surface of the patient's face: A pictorial essay since both techniques involve synchronized rotation between an Xray source and an image receptor around the patient's head that remains stationary.
