Production and use of X-rays
24.2What the syllabus asks of you
- explain that X-rays are produced by electron bombardment of a metal target and calculate the minimum wavelength of X-rays produced from the accelerating p.d.
- understand the use of X-rays in imaging internal body structures, including an understanding of the term contrast in X-ray imaging
- recall and use I = I0e–μx for the attenuation of X-rays in matter
- understand that computed tomography (CT) scanning produces a 3D image of an internal structure by first combining multiple X-ray images taken in the same section from different angles to obtain a 2D image of the section, then repeating this process along an axis and combining 2D images of multiple sections
