Across
- 3. The difference between the x-ray photons that are absorbed photoelectrically versus those that penetrate the body
- 7. Used to describe the ability of the imaging system to distinguish between small objects that attenuate the x-ray beam similarly in digital imaging
- 8. The range of exposure intensities that an image receptor can respond to and acquire image data.
- 12. per unit volume, or the compactness of the atomic particles composing the anatomic part
- 13. The attenuated x-ray beam leaving the patient that is composed of both transmitted and scattered radiation; also known as exit radiation
- 14. Unwanted exposure on the radiographic image that does not provide any diagnostic information
- 15. Scattering that results in the loss of some energy of the incoming photon when it ejects an outer-shell electron from a tissue atom
- 16. The invisible image that exists on the image receptor before it has been processed
- 18. It affects the number of shades of gray available for image display
- 19. Combination of rows and columns of pixels that make up a digital image
- 21. The removal of an electron from an atom
- 22. Incoming photons are not absorbed, but instead lose energy during interactions with the atoms composing the tissue
- 23. The electron ejected from an atom during a Compton scattering event
- 24. X-ray photons that pass through the body to expose the image receptor
Down
- 1. The ejected electron resulting from the Compton effect interaction
- 2. In the diagnostic range, the total absorption of the incident photon by ejecting an inner shell electron of a tissue atom
- 4. The attenuated x-ray beam leaves the patient and is composed of both transmitted and scattered radiation
- 5. An interaction that occurs with low-energy x-rays, typically below the diagnostic range. The incoming photon interacts with the atom, causing it to become excited. The x-ray does not lose energy, but changes direction
- 6. The visible radiographic image on the exposed film after processing
- 9. Those x-ray photons removed from the x-ray beam as a result of the uptake of their energy by body tissues
- 10. The use of a continuous beam of x-rays to create dynamic images of internal structures that can be viewed on a display monitor
- 11. A device hat receives the radiation leaving the patient
- 17. Reduction in the energy or number or photons in the primary x-ray beam after it interacts with the anatomic tissues
- 18. The smallest component of the matrix, which is represented as a single brightness level on a computer monitor
- 20. The electron ejected from an atom during a photoelectric interaction
