In Radiography, when a patient comes in for an exam, the area of interest is lined up directly under the beam. When the exposure is taken all the photons are absorbed through the patient’s body (through fat, bone, muscle) until it reaches the image receptor (IR), this process is called attenuation. When a patient is of larger size, this attenuation can also produce scatter radiation to other parts of the body and even the Radiographer and others within the exam room. As we know, radiation can cause some biological damage; this is why it is very important to use collimation, and shielding. Along with using collimation and shielding another very important but often forgotten about thing we as Radiographers need to know are technique. The main
