Definitions

  • FIGs. IA-B show one embodiment of an acoustic probe including a variably- refracting acoustic lens coupled to an acoustic transducer.
  • the top end and bottom end of housing 110 are substantially acoustically transparent, while the acoustic waves do not penetrate through the side wall(s) of housing 110.
  • Acoustic transducer 20 is coupled to the bottom of housing 110, beneficially by one or more acoustic matching layers 130.
  • processor/controller 210 determines whether or not to scan in another direction, depth, and/or plane. If so, then in step 350, the scan area is selected, and the process repeats at step 310. If not, then in step 355 motion detection processor 270 processes the received acoustic data (perhaps in conjunction with processor/controller 210) to produce images and/or other outputs representing or illustrating motion within a region being scanned by ultrasonic motion detection system 200, such as motion due to patient breathing cycle, heart movement, or patient musculature movement.. Finally, in a step 360, ultrasonic motion detection system 200 outputs the images and/or other outputs that represent the detected motion.
