Solution Overview
Problem
Existing ultrasonic diagnostic apparatuses face difficulties in clearly displaying a biopsy needle's position when the ultrasonic beam direction is not perpendicular to the needle's insertion path, making it challenging to determine if the needle has reached the correct location.
Innovation Solution
An ultrasonic diagnostic apparatus that includes a received beam forming unit to form ultrasonic beams based on echo signals and a display control unit to display images in a mode corresponding to the angle between the beam direction and the biopsy needle's path, allowing easy recognition of the beam angle relative to the needle's path.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If an ultrasonic beam is deflected substantially perpendicularly to the insertion path of the biopsy needle, then the biopsy needle is clearly displayed in the ultrasonic image, but the ultrasonic diagnostic apparatus cannot determine whether the needle has reached the correct location in areas not covered by the deflected beam
Solution Approach 1:
The patent applies dynamics by making the beam direction adjustable rather than fixed. The ultrasonic beam can be deflected in different directions according to the predetermined insertion path of the biopsy needle, allowing the system to adaptively optimize needle visualization for different insertion scenarios while maintaining clear display throughout the procedure
Solution Approach 2:
The system achieves multi-functionality by combining ordinary ultrasonic beam imaging with deflected ultrasonic beam imaging. This allows the same ultrasonic diagnostic apparatus to provide both general tissue imaging and specialized needle position monitoring, ensuring comprehensive coverage of the biopsy procedure regardless of insertion path orientation
2Device complexity
If the beam direction of the ultrasonic beam is fixed in one direction, then the system configuration is simple, but the operator cannot easily recognize the angle between the ultrasonic beam and the biopsy needle path
Solution Approach 1:
The patent implements feedback by providing visual information about the angle between the ultrasonic beam and the biopsy needle path on the display. The display control unit shows the predetermined insertion path and allows the operator to recognize the beam angle, creating a feedback loop that helps the operator adjust the beam direction to optimize needle visualization while maintaining simple system configuration

AI summary
An ultrasonic diagnostic apparatus that can identify the angle of a received ultrasonic beam with respect to the predetermined biopsy path of a biopsy needle. The ultrasonic diagnostic apparatus is characterized by including a received beam forming unit that forms received ultrasonic beams based on the echo signals of ultrasonic waves transmitted into a subject, and a display control unit that displays, in a B-mode image formed based on the received ultrasonic beams, a biopsy guide line in a display mode corresponding to an angle between the beam direction of the received ultrasonic beam and the predetermined biopsy path of a biopsy needle to be inserted into the subject. The biopsy guide line is displayed as, for example, a broken line having a width corresponding to the angle.
