Ultrasound diagnosis apparatus
View Patent ↗An apparatus has: an ultrasound probe that transmits and receives ultrasound waves to and from a subject and has an ultrasound transmission/reception surface; an acoustic coupler that has a different shape for each type and is attachable and detachable so as to cover the ultrasound transmission/reception surface; a generator that, based on the ultrasound waves received by the ultrasound probe, generates an image expanding in a depth direction from the ultrasound transmission/reception surface; and an analyzer that, based on presence/absence and shape of an acoustic coupler region within the image generated by the generator, identifies presence/absence of mounting of the acoustic coupler and a type of the mounted acoustic coupler. Consequently, the apparatus is capable of identifying the acoustic coupler though the ultrasound probe and the acoustic coupler are not provided with special structures.
1. An ultrasound diagnosis apparatus, comprising:
an ultrasound probe provided with an ultrasound transmission/reception surface and an acoustic coupler, the acoustic coupler being provided with the ultrasound probe so as to cover the ultrasound transmission/reception surface;
a generator configured to, based on the ultrasound waves received by the ultrasound probe, generate an image expanding in a depth direction from the ultrasound transmission/reception surface;
an analyzer configured to identify a type of the acoustic coupler, based on a cross-sectional shape of an acoustic coupler within the image generated by the generator; and
a controller configured to control ultrasound transmission/reception conditions of the ultrasound probe,
wherein the controller is further configured to change the ultrasound transmission/reception conditions based on the type of the acoustic coupler identified by the analyzer.
2. The ultrasound diagnosis apparatus according to claim 1 , wherein the analyzer is further configured to store patterns representing various cross-sectional shapes of the acoustic coupler within the image in accordance with the type of the acoustic coupler and identify the type of the acoustic coupler by matching the patterns with the image generated by the generator.
3. The ultrasound diagnosis apparatus according to claim 1 , wherein the controller is configured to, when the type of mounting of the acoustic coupler is the acoustic coupler having the ultrasound transmission/reception surface with a larger radius of curvature than a radius of curvature of the ultrasound transmission/reception surface of the ultrasound probe identified by the analyzer, restricts a range to scan with the ultrasound waves to a range that is narrower than the ultrasound transmission/reception surface of the acoustic coupler.
4. The ultrasound diagnosis apparatus according to claim 1 , wherein the analyzer is further configured to perform the identification at predetermined time intervals.
