Embodiment 1

[0028] figure 1 A flow chart of a multi-frequency imaging method according to an embodiment of the present invention is shown. Such as figure 1 As shown, the method includes the following steps:

[0029] S110: Acquire N types of ultrasonic echoes corresponding to the position to be detected, where the N types of ultrasonic echoes are N different frequency states, and N is a natural number greater than or equal to 2.

[0030] The N kinds of frequency states in this step refer to the N kinds of center frequencies, the upper limit of the frequency interval, the lower limit of the frequency interval, or a combination of any two of the three. For example, the center frequencies of the N types of transducers are different. Such as figure 2 As shown, three kinds of transducers 1, 2, and 3 are used to emit ultrasonic waves and receive ultrasonic echoes at the position to be observed, and these three kinds of transducers are low-frequency, intermediate-frequency, and high-frequenc...

[0037] image 3 A flow chart of another multi-frequency imaging method according to an embodiment of the present invention is shown. Such as image 3 As shown, the method includes the following steps:

[0038] S210: Control N types of transducers on the multi-frequency probe to transmit ultrasonic waves to the position to be detected and receive ultrasonic echoes, and the N types of transducers work in N different frequency states.

[0039] By transmitting and receiving ultrasonic echoes once, an image with a deeper detection depth and an image with a higher resolution can be obtained, which improves the imaging efficiency.

[0040] S220: Decompose at least one of the N types of ultrasonic echoes into more than two groups of frequency component signals.

[0041]The decomposition method may be to detect the ultrasonic echoes to be decomposed by at least two filter functions; or, as an optional implementation of this embodiment, at least two filters may be used to filter the ...

[0049] Figure 4 A functional block diagram of a multi-frequency imaging device according to an embodiment of the present invention is shown. The multi-frequency imaging device can be used to implement the multi-frequency imaging method described in Embodiment 1 or Embodiment 2. Such as Figure 4 As shown, the device includes a first acquisition unit 10 , a fusion unit 20 and an imaging unit 30 .

[0050] The first acquisition unit 10 is configured to acquire N types of ultrasonic echoes corresponding to the position to be detected, where N types of ultrasonic echoes are N different frequency states, and N is a natural number greater than or equal to 2. The fusion unit 20 is used to fuse N kinds of ultrasound echoes to obtain one fusion echo. The imaging unit 30 is used for performing ultrasound imaging according to the fusion echo.

Abstract

The invention discloses a multifrequency imaging method, device and equipment. The method comprises the steps that N kinds of ultrasonic echoes corresponding to a position to be detected are acquired,wherein the N kinds of ultrasonic echoes are N different frequency states, and N is a natural number larger than or equal to 2; the N kinds of ultrasonic echoes are fused, and a fused echo is obtained; ultrasonic imaging is carried out according to the fused echo. According to the multifrequency imaging method, device and equipment, the N kinds of ultrasonic echoes are fused firstly, then ultrasonic imaging is carried out according to the fused echo, and the resolution ratio of a formed image is high; due to the fact that the low-frequency ultrasonic echoes are fused, the investigation depthis large, and the loss of important information carried by original ultrasonic echoes can be reduced. Besides, according to the multifrequency imaging method, deep tissue information can be clearly shown only through one image, frequent switching is not needed, and image observation is convenient.

Description

technical field [0001] The invention relates to the technical field of ultrasonic imaging, in particular to a multi-frequency imaging method, device and equipment. Background technique [0002] Ultrasound imaging technology uses the reflected and scattered echoes generated by ultrasonic waves in tissues to form images for the identification and diagnosis of diseases. Therefore, the steps of ultrasonic imaging are to firstly control the ultrasonic transducer to emit ultrasonic waves toward the tissue and receive ultrasonic echoes, and then perform imaging according to the ultrasonic echoes. When the ultrasonic frequency emitted by the ultrasonic transducer is low, the detection depth is deep but the resolution is low; when the ultrasonic frequency emitted by the ultrasonic transducer is high, the detection depth is shallow but the resolution is high. [0003] Existing ultrasonic imaging methods often use a low-frequency probe integrated with a low-frequency transducer and a ...
