_ is produced when the electron striking the target ejects an inner shell electron of the target atom, then an outer shell fills the vacancy with the release of an x-ray photon. _ is produced when the electron striking the target interacts with the target atom nucleus, slows down, and changes direction The _ often contains small and large filaments within a focusing cupĩ9% of the energy of the electrons striking the target is converted to _. The _ is headed to produce thermionic emission of electrons. What will it be at 4 feet.Ī material that has a higher Z number is _Ī material that has increased tissue thickness is _Ī material that had increased tissue density is _ T or FĪ radiographer receives an exposure of 80 rem standing 2 feet from the patient. Material that allows x-radiation to pass through is termed radiopaque. Ionization can result in biologic damage. When x-rays are absorbed by body tissue they cause ionization of atoms and molecules. X-rays have a higher energy that visible light. The electromagnetic radiation with the highest energy is the radio wave. T or FĮlectromagnetic radiation has no mass. _ is the quantity or amount of matter.Įlectromagnetic radiation travels at 186,000 miles/second. _ is anything that occupies space and has mass. _ is the process of an electron leaving its orbit around a neutral atom. What is the term for two oppositely charged particles? T or FĪ _ is negatively charged and is found in an orbital shell around the nucleus of an atom.Ī _ is positively charges and is in the nucleus of an atom.Ī _ has no electrical charge and is in the nucleus of an atom.
The radiation that exits the X-ray tube port is called secondary radiation. What are the cardinal principles of radiation protection?īefore making an x-ray exposure, the operator should ensure that non-essential persons are out of the x-ray room and the x-ray door is closed T or F _ controls the penetrating ability of x-rays _ controls the quantity of x-rays produced The term from tilting the x-ray table so that the head is lower than the feet The movement of the x-ray tube from 30" to 40" above the image receptor is called_ The correct term for movement of the x-ray tube from the foot end toward the head end of the patient
In a _ image receptor system and electronic plate receives the x-ray beam and produces an electronic signal that is sent directly to a computer for processing and digital image formation. The latent image will become visible after the film is chemically processed in aĪ _ cassette containing a phosphor plate receives the x-ray beam What are the three types of image receptorsĪ _cassette containing film receives the x-ray beam.Ī film based cassette containing film receives the x-ray beam. The device that receives the remnant beam and forms the latent or invisible image
The special mechanism that stops tube movement at a specific location is The device that limits the size of the radiation field What removes scatter radiation and prevents it from reaching the image receptor? The device that includes a tray to hold the image receptor The development of digital radiography grew out of experimentation with Advantages of digital radiography over film/screen imaging systems include:
