<p>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.</p> |
