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.
Claims15
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;
