ULTRASOUND IMAGE ENHANCEMENT AND SUPER-RESOLUTION

摘要

Techniques to improve resolution in an ultrasound system are disclosed. An exemplary apparatus is a portable ultrasound probe having transducer elements and supporting electronics within the probe. The beam is shaped to split the resolution to sub-pixel accuracy. Super resolution sample technique based on interpolation can be used to further increase resolution. In one embodiment the ultrasound system supports ½ crystal physical resolution and ¼ crystal digital resolution.

主权项

1. A method of providing super-resolution in an ultrasound imaging system having a handheld probe including piezoelectric transducer having an array of piezoelectric crystals, comprising:
generating high voltage pulses within the handheld probe in a firing sequence to drive the array of piezoelectric transducer crystals in which the gain a delay of each high voltage pulse coupled to the array of piezoelectric transducer crystals splits the resolution to sub-pixel accuracy.
