Benefits of technology

The technical effect of this patent is to provide an ultrasound diagnostic system and method that can accurately obtain image information on a patient's tissue, without relying on an operator to position the ultrasonic probe. This system can automatically calculate the proper position and posture of the probe, resulting in more reliable and accurate diagnostic images.

Problems solved by technology

However, since there are many organs in the human body, obtaining image information on an organ to be diagnosed appropriately requires a certain degree of skill in moving the ultrasonic probe.

first embodiment

Ultrasonic Diagnostic Imaging System

[0028]The ultrasonic diagnostic imaging system according to this embodiment is an ultrasonic diagnostic imaging system provided with an ultrasonic probe and an image processing section that converts a signal generated when the ultrasonic probe receives ultrasound reflected from an examinee to image information.

[0029]The system includes the following components.

[0030]More specifically, the system includes a measuring unit (may also be referred to as a “coordinate calculation section” in exemplary embodiments which will be described later) that measures a relative position and relative posture of the ultrasonic probe with respect to the examinee using image information on the examinee acquired by the ultrasonic probe.

[0031]Furthermore, the system also includes a control amount calculation unit that calculates an amount of control of the position and posture of the ultrasonic probe based on the measurement result of the measuring unit.

[0032]The syste...

second embodiment

Control Method

[0037]The control method according to this embodiment is a control method for an ultrasonic diagnostic imaging system provided with an ultrasonic probe and an image processing section that converts a signal generated when the ultrasonic probe receives ultrasound reflected from the examinee to image information. More specifically, the method includes the following steps.

a) A measuring step of measuring a relative position and relative posture of the ultrasonic probe with respect to the examinee using image information on the examinee acquired by the ultrasonic probe

b) A control amount calculation step of calculating an amount of control of the position and posture of the ultrasonic probe based on the measurement result of the measuring step

[0038]Furthermore, the method includes at least one of e) and f) below.

e) A probe control step of controlling the position and posture of the ultrasonic probe using the amount of control calculated in the control amount calculation st...

A: Overall Configuration

[0046]FIG. 1 illustrates an overview of an ultrasonic diagnostic imaging system, which is one of the embodiments of the present invention. The ultrasonic diagnostic imaging system of this exemplary embodiment includes an ultrasonic probe 1001, an ultrasonic diagnostic imaging apparatus 1002, a host controller 1003 and a probe position / posture control apparatus 1004. The ultrasonic probe 1001 is used so as to contact an examinee 1005 such as a human body. Furthermore, the ultrasonic probe 1001 is held by the probe position / posture control apparatus 1004. These apparatuses are mutually connected and operate by exchanging a control signal or the like through the connection. The probe position / posture control apparatus 1004 is necessary when automating the operation of the ultrasonic probe 1001 and is not indispensable to the aforementioned present invention. The exemplary embodiments which will be described later illustrate the configuration in the case where th...

Abstract

An ultrasonic diagnostic imaging system not depending on an operator who operates the apparatus is provided. The system includes a measuring unit (coordinate calculation section 2034) that measures a relative position and a relative posture of the ultrasonic probe with respect to an examinee using image information on the examinee acquired by the ultrasonic probe, a control amount calculation unit (2035) that calculates an amount of control of the position and posture of the ultrasonic probe based on the measurement result of the measuring unit and at least one of a probe control mechanism that controls the position and posture of the ultrasonic probe using the amount of control calculated by the control amount calculation unit and a guiding information presentation unit that presents information for guiding movement of the position and posture of the ultrasonic probe using the amount of control calculated by the control amount calculation unit.

Description

TECHNICAL FIELD[0001]The present invention relates to an ultrasonic diagnostic imaging system and a control method thereof.BACKGROUND ART[0002]An ultrasonic diagnostic imaging apparatus (echo) is a diagnostic apparatus that irradiate an examinee with ultrasound, receives ultrasound reflected inside the examinee using a probe and obtains image information from received data. Even when irradiated onto the human body, ultrasound is safe without any particular side effects, and is therefore widely used for diagnostics of various diseases on the medical front lines.[0003]The ultrasound medical system disclosed in Japanese Patent Application Laid-Open No. 2004-499 discloses a medical system that combines a radiation system for radiological treatment with an ultrasonic diagnostic imaging apparatus. The ultrasonic diagnostic imaging apparatus provides positional information using the position of the radiation apparatus as the origin when providing the position of a tumor to be cured.[0004]T...
