Appl. No.:

13/756851
Inventors:

Olivier Roy - Royal Oak MI, US
Steven Schmidt - Clinton Twp MI, US
Cuiping Li - Troy MI, US
Roman Janer - Plymouth MI, US
Xiaoyang Cheng - Ann Arbor MI, US
Jefferey Goll - Lake Oswego OR, US
Assignee:

Delphinus Medical Technologies, Inc. - Plymourth MI
International Classification:

A61B 8/00
A61B 8/08
A61B 8/15
US Classification:

600448
Abstract:

A system and method for imaging a volume of tissue comprising: a modular transducer array, configured to substantially surround the volume of tissue, emit acoustic waveforms toward the volume of tissue, and receive acoustic waveforms scattered by the volume of tissue, comprising a first and a second modular transducer subarray configured to couple to one another; a controller configured to control acoustic signals emitted by the first and the second modular transducer subarrays; an electronic subsystem, coupled to the modular transducer array, comprising a multiplexor and beam-forming elements and configured to receive a set of acoustic data from the first and the second modular transducer subarrays; and a processor configured to analyze the set of acoustic data, determine the distribution of at least one acoustomechanical parameter within the volume of tissue, and render an image of the volume of tissue based on the acoustomechanical parameter.

Appl. No.:

11/320921
Inventors:

Jingkuang Chen - Albuquerque NM, US
Xiaoyang Cheng - Ann Arbor MI, US
Assignee:

STC.UNM - Albuquerque NM
International Classification:

A61B 1/12
US Classification:

600439, 600459, 600462, 600471, 257416
Abstract:

A medical device may include a micro-machined substrate, at least one thermo-electric assembly associated with the substrate, and a cooling system configured to configured to remove heat from the a region of the substrate proximal the substrate. According to various aspects, a method of clearing plaque from a blood vessel may include implanting a micro-device in the blood vessel, wherein the micro-device may include at least one ultrasonic transducer, and operably controlling the micro-device to emit high frequency ultrasonic waves for breaking up said plaque.
