Research Interests
Tissue-induced aberration correction
Current Projects
We are currently investigating a first order solution to tissue aberration. A first order solution is attractive because it can be implemented on our clinical ultrasound scanners. The algorithm is implemented with a specially designed 1.75D, 8x96 element transducer, meaning our transducer has 8 rows with 96 elements per row. This gives us the ability to correct for focal aberrations in both lateral and elevation dimensions. Because we are using a modified clinical scanner and a specially designed transducer not intended for use on the system our success has been limited by our slow acquisition time. At this point we are working on integrating the adaptive imaging beam sequences, and 1.75D transducer with a new piece of hardware that should make our imaging rate four times faster. This improved imaging rate should result in better clinical correction of aberrations.
