PART I- MAMMOGRHAPY MACHINE
Across
- 5. The filter material commonly paired with a molybdenum target for conventional mammographic beam production.
- 6. The tube region where thermionic emission supplies electrons.
- 12. The selectable detector location used by the exposure-control system to sample breast density.
- 13. The standard projection in which the x-ray beam travels from superior to inferior.
- 14. The component beneath the breast that detects transmitted x-rays and converts them into image-forming electrical information.
- 15. The small compression device used to isolate and compress a localized breast region.
- 17. The filter material commonly paired with a rhodium target to produce a more penetrating beam.
- 19. The device placed between patient and receptor to reduce scattered radiation.
- 20. The modified projection that pulls breast tissue anteriorly to better visualize posterior tissue.
- 23. The radiolucent device that applies controlled force to flatten the breast against the receptor.
- 24. The support that elevates the breast above the detector for geometric magnification.
- 25. A detector that first converts x-rays into light before generating an electrical signal.
Down
- 1. The x-ray target material whose characteristic radiation is especially suitable for mammographic imaging.
- 2. A detector that converts x-rays directly into electrical charge without an intermediate light step.
- 3. The numerical characteristic describing the relationship between lead strip height and interspace width.
- 4. The rotating tube component containing the x-ray target and designed to dissipate heat.
- 7. The system that automatically terminates or adjusts exposure according to radiation reaching the detector.
- 8. The photoconductor commonly used in direct-conversion mammographic detectors.
- 9. The standard oblique projection demonstrating breast tissue along with the pectoral region.
- 10. The negatively charged electrode that emits electrons toward the target.
- 11. The intentional intensity variation across the radiation field caused by the angled target surface.
- 16. The technique that acquires multiple low-dose projections and reconstructs breast slices.
- 18. The imaging benefit produced when compression decreases overlapping anatomical structures.
- 21. The positively charged electrode containing the x-ray-producing target.
- 22. The transparent acrylic material historically used for mammographic compression paddles.
