no. 1 Embodiment approach

[0092] FIG. 1 is a basic configuration diagram of an ultrasonic diagnostic apparatus having an ultrasonic probe diagnostic function according to a first embodiment of the present invention. This ultrasonic diagnostic apparatus includes a main unit 100 and an ultrasonic probe 200 . The ultrasonic probe 200 includes a connector 201 , a probe unit 202 , a cable unit 203 and an identification information output unit 204 .

[0093] The ultrasonic probe 200 is connected to the main unit 100 through a connector 201 . The probe unit 202 is configured by arranging a plurality of ultrasonic oscillators 202a one-dimensionally or two-dimensionally. Each ultrasonic oscillator 202 a is connected to the connector 201 through a signal line 203 a provided in the cable unit 203 . Electrodes 201a connected to these signal lines 203a are provided in the connector 201 . That is, the ultrasonic probe 200 is formed by paralleling a plurality of channels including electrodes 201a, ultrasonic oscil...

no. 2 Embodiment approach

[0148] Next, the operation of the ultrasonic diagnostic apparatus according to the second embodiment will be described.

[0149] When medical diagnosis of a subject is performed using the ultrasonic probe 200 , by making effective use of the medical diagnosis unit 411 , information useful for medical diagnosis can be presented similarly to well-known ultrasonic diagnostic devices.

[0150] On the other hand, when diagnosing the ultrasonic probe 200 , as shown in FIG. 15 , a maintenance worker sets a test object in a medium such as water in a container such as a water tank, and sets the probe unit 202 against the test object. The maintenance personnel adjust the distance between the ultrasonic probe 200 and the test object, so that the reflective surface of the test object is on the focal point of the ultrasonic probe 200 .

[0151] When it is necessary to diagnose the ultrasonic probe 200 , the control unit 410 reads out the identification information output by the identificat...

no. 3 Embodiment approach

[0158] Next, the operation of the ultrasonic diagnostic apparatus according to the third embodiment will be described.

[0159] The conditions for diagnosing the ultrasonic probe 200 are the same as those of the second embodiment. In addition, the operation of the control unit 410 up to acquisition of focus information is performed in the same manner as in the second embodiment.

[0160] The control unit 410 determines the repetition periods Tf1 , Tf2 , Tf3 . . . Tfn in the following manner based on the focal length F indicated by the acquired focus information. That is, the control unit 410 first calculates the time Ta required from when the ultrasonic probe 200 sends the ultrasonic signal to when the ultrasonic probe 200 receives the reflected ultrasonic signal generated by the test object according to Ta=2F / C. Then the control unit 410 obtains the reference value Tf of the repetition period from Tf=ts+Ta+td. Next, the control unit 410 obtains the repetition period Tfi (i=...

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.

Description

[0001] This application is a divisional application of the application with the application number 200510096688.9, the application date is August 31, 2005, and the invention title is "ultrasonic detector diagnostic device, ultrasonic diagnostic device and ultrasonic detector diagnostic method". technical field [0002] The present invention relates to an ultrasonic probe diagnostic device for diagnosing an ultrasonic probe used in the ultrasonic diagnostic device, an ultrasonic probe diagnostic method, and an ultrasonic diagnostic device having a function of diagnosing an ultrasonic probe. Background technique [0003] Techniques for diagnosing an ultrasonic probe based on signals received by the ultrasonic probe are disclosed in, for example, JP-A-238243 and JP-10-227772. [0004] For example, in JP-A-2003-144432, it is disclosed that in order to detect the transmission / reception characteristics of an ultrasonic probe, the ultrasonic wave reflected by a test object such as a...
