Oct 21, 2024 · Chest x-ray lines and tubes can be easily assessed and should be the first thing you look at when reviewing a chest x-ray. The assessment of their position is important, but they also give you an idea of how sick the patient is and narrow down the differential diagnosis.

Explain how the parts of the x-ray tube function to produce x-rays. Place the events involving the production of x-rays in chronological order. Differentiate between the terms anode, target and focal spot. Describe the interactions in the anode and the x-ray energies they produce.
Apr 18, 2023 · This chapter describes the x-ray production process, characteristics of the x-ray beam, x-ray tube design x-ray generator components, and factors that affect exposure and exposure rate.
Basics of X-ray Physics. X-ray production. Key points. X-rays are produced by interaction of accelerated electrons with tungsten nuclei within the tube anode. Two types of radiation are generated: characteristic radiation and bremsstrahlung (braking) radiation.
Key points. X-rays travel in straight lines. Body parts further away from the detector are magnified compared with those that are closer. Occasionally magnification can be helpful in localising abnormalities. X-rays travel in straight lines and a beam of X-rays diverges from its source.
Mar 6, 2016 · The x-ray beam is polyenergetic (many energies) and consists of a wide range of energies known as the x-ray emission spectrum. The lowest energies are always approximately 15 to 20 keV, and the highest energies are always equal to the kVp set on the control panel.
