Abstract
A system for pulmonary elastography includes an ultrasound probe (120) configured to evaluate tissue of a target area by transmitting a signal and receiving a response. A contact device (126) is coupled to the ultrasound probe to provide contact between the ultrasound probe and the tissue. An image processing module (110) is configured to output one or more elastograms according to the response.
Claims19
A system for pulmonary elastography, comprising:
- a probe configured to be inserted within an airway of a subject and to evaluate tissue of a target area relative to the airway by transmitting at least one push pulse to the target area resulting in an ultrasound shear wave;
- a contact device coupled to the probe to provide contact between the probe and the tissue;
- an additional probe configured to measure a propagation speed of the ultrasound shear wave, and
- an image processing module configured to output one or more elastograms according to a measurement of the propagation speed of the ultrasound shear wave by the additional probe.

A method for performing pulmonary elastography, comprising:
- evaluating tissue of a target area using a probe inserted within an airway of a subject and by transmitting at least one push pulse resulting in an ultrasound shear wave;
- employing a contact device coupled to the probe to provide contact between the ultrasound probe and the tissue;
- providing an additional probe configured to measure a propagation speed of the ultrasound shear wave;
- and
- outputting one or more elastograms according to the propagation speed of the ultrasound shear wave.
2 more elements
A system for pulmonary elastography, comprising:
- a probe configured be inserted within an airway of a subject and to evaluate tissue of a target area by transmitting at least one push pulse to the target area resulting in an ultrasound shear wave;
- a compression device decoupled from the probe to generate a compression on the tissue,
- wherein the probe is configured to evaluate the tissue under the compression of the tissue by the compression device;
- an additional probe configured to measure a propagation speed of the ultrasound shear wave;
- and
- an image processing module configured to output one or more elastograms according to a measurement of the propagation speed of the ultrasound shear wave by the additional probe.
