Deformed example 1

[0089] The partial scanning area in the above embodiment is determined based on the current position of the tip of the puncture needle 100 or the expected arrival position corresponding to the current position. In this case, in conjunction with the movement of the current position of the tip of the puncture needle 100, the partial scanning area also moves. In needle biopsy or RFA treatment, it is intended to observe the target site, but sometimes the puncture needle 100 moves unintentionally. When the position of the partial scanning area is determined in conjunction with the current position of the tip of the puncture needle 100, if the puncture needle 100 is pulled out from an observation target site such as a target site, the partial scanning area deviates from the target site. Therefore, the operator must adjust the position of the puncture needle 100 every time the puncture needle 100 deviates from the observation target site. The partial scanning area in Modification 1 ...

Deformed example 2）

[0095] The partial scanning area in the above embodiment includes the position of the tip of the puncture needle 100 or the expected arrival position of the tip. However, the partial scanning area in this embodiment is not limited to this. The partial scan area in Modification 2 is determined based on the predicted route based on the current position of the distal end of the puncture needle 100 . Hereinafter, an ultrasonic diagnostic apparatus and an ultrasonic imaging method according to Modification 2 will be described. In addition, in the following description, the same code|symbol is attached|subjected to the component which has substantially the same function as this embodiment, and description is repeated only when necessary.

[0096] Figure 13 It is a diagram for explaining the determination process of the partial scanning region R2 in the modification 2. In addition, the partial scanning region R2 of Modification 2 is assumed to be a cross section SC. Such as Fi...

Abstract

The accuracy of ultrasound examination using a needle inserted into the subject is improved. The vibrator (2a) generates ultrasonic waves and converts the ultrasonic waves from the subject into echo signals. The transmission unit (13) supplies a drive signal to the vibrator (2a). The receiving unit (15) performs signal processing on the echo signal from the vibrator (2a). The detection unit (4) detects the position of the distal end of the puncture needle (100). A scan area setting unit (11) sets a second scan area smaller than the first scan area based on the first scan area in the subject and the position of the detected tip. The transmission / reception control unit (17) controls the transmission unit (13) and the reception unit (15), and switches between the ultrasonic scanning of the first scanning area and the second ultrasonic scanning of the second scanning area in accordance with an instruction from the operator.

Description

technical field [0001] Embodiments of the present invention relate to an ultrasonic diagnostic apparatus and an ultrasonic scanning method. Background technique [0002] Ultrasonic diagnostic devices can display heart pulsation or fetal activity in real time through a simple operation such as bringing an ultrasonic probe into contact with a body surface, and are highly safe. Therefore, the ultrasonic diagnostic apparatus can repeatedly perform inspections. In addition, ultrasonic diagnostic devices have been developed that are smaller in system scale than other diagnostic equipment such as X-ray, CT, and MRI, and can be carried with one hand. Such a small ultrasonic diagnostic apparatus can be easily inspected by moving to the bed side. Ultrasonic diagnostic equipment does not have radiation like X-rays, and can be used in obstetrics and gynecology, home medicine, and the like. [0003] In recent years, intravenously administered ultrasound contrast agents have been comme...
