Diagnostic Imaging

2. is used to describe tissues that reflect less sound back to the transducer than surrounding tissues. Hypoechoic areas appear darker than surrounding tissues
6. The differences in radiographic density between adjacent areas on a radiographic image
8. The chemical that makes the image on the the film visible
10. is used to describe tissues that reflect more sound back to the transducer than surrounding tissues, hyperechoic area appear brighter than surrounding tissues.
12. On radiographs the air or lung tissues will appear black or transparent because it allows more of the radiation to pass through.
13. With increasing density the tissue will appear whiter, or not able to be seen through, as it absorbs more of the radiation

1. Removes the unchanged silver halide crystals from the film emulsion leaving the black metallic silver.
3. negatively charged, generates electrons
4. positively charged, produces x-rays at the focal spot when fast moving electrons collide with the anode
5. structure exhibits the same brightness as its surrounding structure, same echogenicity.
7. free from echoes and reverberations
9. The dose of radiation for someone who is occupationally exposed measured by a dosimetry badge.
11. An image produced by radiation on film or electric image to a computer screen.
14. An imaging modality that uses sound waves that interact with tissues and are reflected back to create an image.
