Problems solved by technology

Therefore, depending on whether the receiving beams are obtained from the same transmission beam or from different transmission beams, there is a significant change, the uniformity of the image and the display of the boundary between the receiving beams become remarkable, and it is easy to cause a problem in the arrangement direction of the acoustic transmission lines. stripe
In addition, in the two-dimensional Doppler, in the case of coloring and displaying time changes, since the boundary between when the change is zero and not displayed in color, and when it is colored with a change is obvious, it is easy to cause a problem due to the presence or absence of data. The fringes in the direction of the acoustic transmission line

no. 3 Embodiment approach

[0126] Figure 7 It is a functional block diagram showing a configuration example of the ultrasonic diagnostic apparatus according to the third embodiment of the present invention. The present embodiment relates to an ultrasonic diagnostic apparatus having a filter coefficient control function corresponding to the depth of reception. In addition to the configuration of the first embodiment, this ultrasonic diagnostic apparatus is provided with a depth information generation unit 17 that supplies received depth information to a filter coefficient calculation unit 16 .

[0127] According to this configuration, it is possible to set different filter coefficients according to the depth of image data. For example, if Figure 8 As shown, when the interval of the acoustic transmission lines 18 differs depending on the depth and thus the interval of the image data D on adjacent acoustic transmission lines 18 differs depending on the depth, the degree of correlation that differs depe...

Abstract

There is provided first storage means (3) for storing digital reception beam data converted from a reception beam formed from an ultrasonic received signal; first control means (2) for controlling reading and writing of data from / in the first storage means; a filter coefficient calculation portion (5) for calculating a filter coefficient based on information on the reception beam, the information including a positional relationship between the reception beam and a transmission beam; and a first spatial filter operation portion (4) for subjecting each of a plurality of the reception beam data including data of beams received in parallel from a single transmission beam to filtering processing for reducing a difference in image quality between adjacent beams based on the filter coefficient. Image data output from the first spatial filter operation portion are converted into scanning of a display monitor (8) so as to display an image on the display monitor. In an ultrasonic diagnosis apparatus having a parallel reception function, it is possible to display a high-quality ultrasonic image in which stripes are generated less in a direction in which acoustic lines are arranged and that is well defined in detail.

Description

technical field [0001] The present invention relates to an ultrasonic diagnostic apparatus having a parallel reception function of generating a plurality of reception beams from the same transmission beam. Background technique [0002] Ultrasonic diagnostic equipment such as Figure 13 Shown is a device that displays an ultrasonic image based on two-dimensional information obtained by scanning an ultrasonic beam with an ultrasonic probe 30 that transmits and receives ultrasonic waves to a subject. The signal received by the ultrasonic probe 30 is supplied to a spatial filter processing circuit 32 via a signal processing unit 31 . The spatial filter processing circuit 32 is arranged before the image display conversion unit 33 and is composed of a spatial filter for reducing noise of the received signal. The control circuit 34 controls the filter coefficient of the spatial filter processing circuit 32 so that it changes from near the vibrator surface of the acoustic data towa...
