Abstract

An ultrasound probe diagnosing apparatus which diagnoses an ultrasound probe having an array of a plurality of ultrasound transducing elements on the basis of how the ultrasound probe receives reflected ultrasound waves from a test object placed to face the ultrasound probe, includes a part which detects a posture of the ultrasound probe with respect to the test object by comparing reflected ultrasound signals received by at least some of the plurality of ultrasound transducing elements, and a presenting part which presents information based on the detected posture.

First claim

What is claimed is:

1. An ultrasound probe diagnosing system, comprising:
an ultrasound probe including an array of a plurality of ultrasound transducing elements configured to diagnose the ultrasound probe on the basis of how the ultrasound probe receives reflected ultrasound waves from a test object placed to face the ultrasound probe;
a control microprocessor configured to:
variably set transmission/reception periods in repetitive ultrasound wave transmission/reception for each ultrasound wave transmission/reception, the transmission/reception periods being variably set so that times of the transmission/reception periods are sequentially incremented;
execute, for at least one of the ultrasound transducing elements, a processing of adding reflected ultrasound signals repeatedly output from one of the plurality of ultrasound transducing elements for each of said set transmission/reception periods while leading edges of the reflected ultrasound signals are matched with each other; and
diagnose the ultrasound probe on the basis of at least one of the added reflected ultrasound signals by using the at least one of the added reflected ultrasound signals in a posture determination.

2. An ultrasound diagnostic system, comprising:
an ultrasound probe including an array of a plurality of ultrasound transducing elements and obtains information for ultrasound probe diagnosis on a subject to be examined on the basis of reflected ultrasound waves received from the subject by the ultrasound probe;
a microprocessor configured to:
variably set repetition transmission/reception periods for each ultrasound wave transmission/reception with respect to a test object different from the subject, the transmission/reception periods being variably set so that times of the transmission/reception periods are sequentially incremented;
execute, for at least one of the ultrasound transducing elements, a processing of adding reflected ultrasound signals repeatedly output from one of the plurality of ultrasound transducing elements for each of said set transmission/reception periods while leading edges of the reflected ultrasound signals are matched with each other; and
diagnose the ultrasound probe on the basis of at least one of the added reflected ultrasound signals by using the at least one of the added reflected ultrasound signals in a posture determination.

3. An ultrasound probe diagnosing method of diagnosing an ultrasound probe including an array of a plurality of ultrasound transducing elements on the basis of how the ultrasound probe receives reflected ultrasound waves from a test object placed to face the ultrasound probe, comprising:
variably setting transmission/reception periods in repetitive ultrasound wave transmission/reception for each ultrasound wave transmission/reception, the transmission/reception periods being variably set so that times of the transmission/reception periods are sequentially incremented;
executing, for at least one of the ultrasound transducing elements, a processing of adding reflected ultrasound signals output repeatedly output from one of the plurality of ultrasound transducing elements for each of said set transmission/reception periods while leading edges of the reflected ultrasound signals are matched with each other; and
diagnosing the ultrasound probe on the basis of at least one of the added reflected ultrasound signals by using the at least one of the added reflected ultrasound signals in a posture determination.
