Abstract

Techniques of this disclosure are for a transducer array device, method and system. An ultrasound wrap for securing an array of piezoelectric transducers at a thoracic cavity anterior for echocardiology imaging, the ultrasound wrap including a transducer portion having an array of piezoelectric transducers mounted to an inner concave surface of a semi-rigid structure, and a securing portion extending from the transducer portion and comprising flexible material securely fitting around the thorax of a patient limiting the movement of the transducer portion.

Claims (50)

1 . An ultrasound imaging device comprising:

a transducer portion having transducer arrays thereon and a location sensor for determining a position of the transducer portion, at least one of the transducer arrays comprising a plurality of ultrasound phased array transducers each including an array of transducer elements arranged linearly along an array axis, at least one of the transducer arrays further comprising more than one array group of transducers and each array group of transducers simultaneously receives power,

a computing device in communication with said transducer portion, where the computing device comprises:

a first database including a plurality of condition indicators associated with cardiac conditions;

a second database including ultrasound imaging settings, including user input, and a plurality of image data;

a processor configured to receive signals from the transducer arrays and control the transducer arrays to acquire the plurality of image data from the transducer arrays; and

a non-transitory computer readable medium encoded with instructions for the computing device coupled to said processor to:

control the transducer arrays to receive the image data;

compare the plurality of image data with the plurality of condition indicators associated with cardiac conditions stored in the first database;

determine a cardiac condition based on the compared plurality of image data and the plurality of condition indicators associated with stored cardiac conditions;

determine a weighted probability that at least one of the plurality of condition indicators corresponds to a likelihood of cardiac abnormality; and

generate a graphical element based on the determined cardiac condition.

2 . The ultrasound imaging device of claim 1 , wherein at least one of the transducer arrays includes at least one piezoelectric transducer.

3 . The ultrasound imaging device of claim 1 , wherein the condition indicators comprise at least one of a thickness of heart ventricles, valve thickness, structural abnormalities of the heart, or blood flow.

4 . The ultrasound imaging device of claim 1 , wherein the transducer portion comprises a semi-rigid transducer housing.

5 . The ultrasound imaging device of claim 4 , wherein the transducer housing comprises a concave inner side upon which the transducer arrays are disposed.

6 . The ultrasound imaging device of claim 1 , wherein the first database further comprises a threshold value for condition indicators.

7 . The ultrasound imaging device of claim 6 , wherein the non-transitory computer readable medium is further encoded with instructions for the computing device coupled to said processor to compare the image data with the threshold value for the condition indicators to determine if a threshold for potential cardiac condition is met.

8 . An imaging device comprising:

a transducer housing;

a location sensor for determining a position of the transducer housing;

an array of transducers coupled to the transducer housing, the array of transducers comprising a plurality of ultrasound phased array transducers each including an array of transducer elements arranged linearly along an array axis, the array of transducers further comprising more than one array group of transducers and each array group of transducers simultaneously receives power;

acquire image data from the array of transducers,

compare said image data to a plurality of condition indicators,

determine a weighted probability that at least one of the plurality of condition indicators corresponds to a likelihood of cardiac abnormality; and

generate a graphical element based on the determined cardiac condition;

wherein the transducer housing is configured to position the array of transducers on a patient to produce consistent images without requiring a trained technician; and

wherein the plurality of condition indicators comprise at least one of a thickness of heart ventricles, valve thickness, structural abnormalities of the heart, or blood flow.

9 . The imaging device of claim 8 , wherein the computing device determines the weighted probability based on at least one of a geographic location, an indicator of racial information, a birth date, a weight, a height or other physical data.

10 . The imaging device of claim 8 , wherein the array of transducers includes at least one piezoelectric transducer.

11 . The ultrasound imaging device of claim 8 , wherein the housing further comprises a location sensor for determining a position of the array of transducers.

12 . The ultrasound imaging device of claim 8 , wherein the array of transducers comprises more than one array group of transducers and each array group of transducers simultaneously receives power.

13 . The ultrasound imaging device of claim 8 , wherein the housing comprises a semi-rigid transducer housing.

14 . An imaging device comprising:

a transducer housing comprising a plurality of transducers and a location sensor for determining a position of the transducer housing, at least one of the plurality of transducers comprising a plurality of ultrasound phased array transducers each including an array of transducer elements arranged linearly along an array axis, the array of transducers further comprising more than one array group of transducers and each array group of transducers simultaneously receives power; and

a computing device in communication with the plurality of transducers, said computing device comprising:

a first database including a plurality of condition indicators

a second database including ultrasound imaging settings, including user input, and a plurality of image data;

a processor configured to receive signals from the transducer arrays and control the transducer arrays to acquire the plurality of image data from the transducer arrays; and

a non-transitory computer readable medium encoded with instructions for the computing device to

receive image data from the plurality of transducers,

compare the received image data with the plurality of condition indicators, and

determine the weighted probability that at least one of the condition indicators corresponds to a likelihood of cardiac abnormality, and

generate a graphical element based on the determined cardiac condition.

15 . The imaging device of claim 14 , wherein the computing device determines the weighted probability based on at least one of a geographic location, information, a birth date, a weight, a height or other physical data.
