- 2.2: Radiation in Medical Imaging - The X-ray Tube
- X-ray tubes are found in a wide variety of imaging devices, Computed Tomography (CT), portable x-ray machines, mammography machines, fixed position x-ray machines, fluoroscopy units, and c-arm x-ray machines.
- 2.4: Radiation Interaction with Biological Matter
- When x-rays or gamma rays interact with human tissue, we must consider the mechanisms of interactions that take place, and what the detriment is to the tissue. To begin that conversation, we must lay down some ground work for the discussion. This includes, among many things, the understanding that human tissue is comprised of many millions of cells, containing organic and inorganic compounds comprised of water, minerals, proteins, nucleic acids, and lipids.
