Abstract
The artificial body part control system using ultrasonic imaging includes of an ultrasonic transducer coupled with an ultrasonic image analyzer which may be adapted to transmit a control signal to an artificial body part.
Claims20
A system, comprising:
- at least one ultrasonic transducer configured to produce two-dimensional image ultrasound data of tissue;
- and
- an image analyzer coupled to the at least one ultrasonic transducer configured to:
- detect, based on the two-dimensional image ultrasound data, a characteristic pattern of echogenicity and a characteristic pattern of echo texture, wherein the characteristic pattern of echogenicity and the characteristic pattern of echo texture indicate an origin and a magnitude of movement of a plurality of muscle tissues and a plurality of bones;
- generate, based on the detected characteristic pattern of echogenicity and the detected characteristic pattern of echo texture, image features corresponding to an intended activity;
- determine output signals adapted to control individual movement of one or more of a plurality of artificial body parts to effectuate the intended activity;
- associate the output signals with the generated image features;
- and
- store the image features and the associated output signals in a reference database.

A method, comprising:
- producing at least a temporal sequence of two-dimensional image ultrasound data of tissue;
- detecting a characteristic pattern of echogenicity and a characteristic pattern of echo texture, wherein the characteristic pattern of echogenicity and the characteristic pattern of echo texture indicate an origin and a magnitude of movement of a plurality of muscle tissues;
- generating, based on the detected characteristic pattern of echogenicity and the detected characteristic pattern of echo texture, image features corresponding to an intended activity, wherein the image features corresponding to the intended activity comprise one or more of an intensity of movement of the plurality of muscle tissues, a rate of movement of the plurality of muscle tissues, or a duration of movement of the plurality of muscle tissues;
- determining output signals adapted to control individual movement of a plurality of artificial body parts to effectuate the intended activity;
- associating the output signals with the image features;
- and
- storing the image features and the associated output signals in a reference database.
