Across
- 2. fraction of time that pulsed ultrasound is on
- 3. sound scattered back in the direction from which it originally came
- 7. temperature at which an element material loses its piezoelectric properties
- 10. spatial pulse length divided by 2
- 12. this layer is attached to the face of a transducer element to improve transmission of sound into the body
- 13. related to a procedure or system in which data are represented by numeric digits
Down
- 1. beamwidth
- 4. a sophisticated form of transmission in which the driving voltage pulses have intrapulse variations in amplitude, frequency, and/or phase
- 5. binary digit
- 6. unit of viscosity
- 7. region of high density and pressure in a compressional wave
- 8. this material is attached to the back of a transducer element to reduce pulse duration
- 9. imaging depth
- 11. the principle that it is prudent to obtain diagnostic information with the least amount of possible energy exposure to the patient
