Problems solved by technology

Higher harmonics are not only in the long-axis direction, but also in the short-axis (slice direction) ultrasound beam is thinner, so it is beneficial to the B (Brightness) mode image (normal mode image), but for the puncture mode image, the puncture needle that deviates from the slice Easy to break away from the ultrasound beam, difficult to detect the puncture needle

Abstract

The present invention relates to an ultrasonic image diagnosis device. The ultrasonic imaging diagnostic device (U) has: a transmitting part (12), which alternately repeats a first pulse signal and a second pulse signal whose polarity is reversed, and outputs it to the ultrasonic probe (2); a receiving part (13); The memory (14) stores the first sound ray data corresponding to the first pulse signal; the adding unit (15) adds the first sound ray data to the second sound ray data corresponding to the second pulse signal; row The signal processing unit (C) generates fundamental wave data and higher harmonic wave data; the puncture needle emphasis signal processing unit (23) generates fundamental wave image data, and generates needle image data of the puncture needle according to the fundamental wave image data; The high-order harmonic signal processing part (25) generates high-order harmonic image data; the synthesis part (27) synthesizes needle image data and high-order harmonic image data; and the control part (30) synthesizes the image data to display.

Description

technical field [0001] The present invention relates to an ultrasonic image diagnosis device. Background technique [0002] Conventionally, there is an ultrasonic imaging diagnostic apparatus that examines the internal structure of a subject by irradiating ultrasonic waves inside the subject and receiving the reflected waves (echoes) to perform predetermined signal data processing. Such an ultrasonic imaging diagnostic apparatus is widely used for various purposes such as medical inspection, treatment, and inspection of the inside of a building structure. [0003] Such an ultrasonic imaging diagnostic apparatus is known to obtain an image with high contrast by imaging harmonic components (for example, frequencies 2f0, 3f0, etc.) relative to the fundamental wave component (frequency f0) of a transmission signal. This shooting method is called tissue harmonic imaging (Tissue Harmonic Imaging). [0004] The above-mentioned high-order harmonic components are mainly generated d...
