no. 1 approach

[0017] First, use figure 1 The overall configuration of the ultrasonic diagnostic apparatus according to the first embodiment will be described. figure 1 It is a diagram for explaining the overall configuration of the ultrasonic diagnostic apparatus 1 according to the first embodiment. Such as figure 1 As shown, the ultrasonic diagnostic apparatus 1 of the first embodiment includes an ultrasonic probe 11a, an ultrasonic probe 11b, a probe connector (probe connector) 11c, an input device 12, a monitor (monitor) 13, a position information acquisition device 14, and an apparatus main body 100. , and connect to the network.

[0018] The ultrasonic probe 11a and the ultrasonic probe 11b have a plurality of piezoelectric vibrators that generate ultrasonic waves based on drive signals supplied from a transmission and reception unit 110 included in the device main body 100 described later, and receive ultrasonic waves from the subject. The reflected wave of P is converted into an e...

[0072] In addition, although the first embodiment has been described above, it can be implemented in various forms other than the above-mentioned first embodiment.

[0073] (1) Sensor switching processing

[0074] In the first embodiment described above, the case where one position sensor is used for a plurality of ultrasonic probes has been described. However, the embodiment is not limited to this, and for example, position sensors may be attached to each of the plurality of ultrasonic probes. In this case, when the ultrasonic probe is switched, the position sensor is also switched. Here, switching of the position sensor may be performed manually or automatically.

[0075] Figure 5 It is a figure for demonstrating the correspondence table of the ultrasonic probe and the position sensor of 2nd Embodiment. For example, when the position sensor is automatically switched, the internal storage unit 170 stores a correspondence table indicating the correspondence between the ul...

Abstract

An ultrasound diagnostic apparatus according to an embodiment includes a memory unit and a converting unit. The memory unit stores therein conversion information, for each ultrasonic probe, converting a coordinate of an attachment position of a position sensor attached to an ultrasonic probe into a coordinate of a predefined position on a surface for transmitting and receiving ultrasonic waves on the ultrasonic probe. When the ultrasonic probe is replaced with another ultrasonic probe, the converting unit acquires conversion information corresponding to the replacing ultrasonic probe and uses the conversion information thus acquired to convert the coordinate of the attachment position of the position sensor attached to the replacing ultrasonic probe into the coordinate of the predefined position.

Description

[0001] REFERENCE TO RELATED APPLICATIONS: This application enjoys the benefit of priority of Japanese Patent Application No. 2011-267034 filed on December 6, 2011 and Japanese Patent Application No. 2012-238621 filed on October 30, 2012. All content is used for this application. technical field [0002] The present invention relates to an ultrasonic diagnostic device and a coordinate conversion method (computer program product: computer program product). Background technique [0003] Conventionally, ultrasonic diagnostic devices have been used as non-invasive diagnostic devices for periodic observation of patients with diseases with a high risk of developing into cancer. For example, ultrasonic diagnostic imaging devices are used for regular observation of patients with diseases with a high risk of transition to liver cancer, such as hepatitis and cirrhosis. [0004] In recent years, inspections by X-ray CT (Computed Tomography: Computed Tomography) apparatuses and MRI (Mag...
