Image quality versus optimization

Image quality plays an essential role in radiographic dose optimisation. Optimisation involves producing an image with acceptable image quality and low patient radiation dose (ALARP principle) (Department of Health, 2007; ICRP, 2006). Estimates of the radiation dose received by patients are relatively easy to make; by contrast, image quality assessments …

Computed versus analogue radiography

Despite the numerous differences between CR and analogue, they share one feature in common: their response to radiation exposure. Anatomical information is acquired in analogue radiography after the X-ray photons pass through the object and carry information concerning the region of interest.  Following this, a screen absorbs the photons’ energy, …
