Embodiment 1

[0048] This embodiment provides a figure 1 The system for improving the quality of ultrasound images in real time is shown to realize the method for improving the quality of ultrasound images in real time.

[0049] The specific workflow of the system is as follows: figure 2 As shown, for a given ultrasound image, it is preprocessed into a digital image of the specified size and format

[0050] I 0 (x,y);

[0051] Transformation module for ultrasound images I 0 (x, y) is transformed in the time-frequency domain to obtain a two-dimensional spatial spectrum:

[0052] S 0 (k x ,ky ) = FT(I 0 (x,y)),

[0053] The time-frequency domain transformation adopts two-dimensional fast Fourier transform, that is, 2D FFT;

[0054] Divide the module on the spatial spectrum S 0 (k x ,k y ) to perform division operation to obtain J=100 subspace spectra

[0055] {S j (k x ,k y )}, J=1,2,3...100;

[0056] In this example, using image 3 In the segmentation method shown, the ent...

Embodiment 2

[0069] Instructions attached Figure 5 The reference signs in include: ultrasonic probe 1, cleaning box 2, cleaning cloth roll 3, liquid pump 4, fixed teeth 5, shaft roller 6, cutting head 7, bracket 8, liquid cavity 9, controllable valve 10.

[0070] The acquisition of ultrasonic images must be carried out through the contact between the ultrasonic probe and the human body. In order to better obtain ultrasonic images and eliminate the hidden danger of disease transmission through the ultrasonic probe, the difference between this embodiment and the first embodiment is that this embodiment also includes A cleaning device for an ultrasonic probe, the device is basically as Figure 5 As shown, it includes: a cleaning box 2, a liquid cavity 9 for inserting the ultrasonic probe 1 is arranged obliquely on the cleaning box 2, and a liquid pump for delivering cleaning liquid to the liquid cavity 9 is also provided in the side wall of the cleaning box 2 4. There is a liquid outlet hol...

Abstract

This patent discloses a method for improving the quality of ultrasonic images in real time, including: (1) performing time-frequency domain transformation on ultrasonic two-dimensional images to obtain spatial spectra; (2) performing division operations on spatial spectra to obtain subspace spectra; (3) ) Perform inverse time-frequency domain transform on the subspace spectrum to obtain the sub-image; (4) Calculate the coherence factor and perform weighting processing on the original image to obtain an ultrasound image with improved quality. The patent also discloses a system for improving the quality of ultrasonic images in real time. While removing noise, the invention improves image resolution, suppresses side lobes, effectively improves the quality of ultrasonic images, and has good real-time performance and low computational complexity.

Description

technical field [0001] The invention belongs to the technical field of ultrasonic imaging, and in particular relates to a method and system for improving the quality of ultrasonic images in real time. Background technique [0002] Ultrasound Imaging (Ultrasound Imaging) technology obtains ultrasonic images of the internal structure of objects based on ultrasonic scattered waves around objects, and is widely used in the fields of medical imaging and nondestructive testing. In the ultrasonic imaging technology, the ultrasonic waves transmitted and received by the ultrasonic sensor have the nature of ultra-wideband signals. The target information can be obtained by irradiating and observing the target at different angles, and a large target spatial spectrum can be obtained to achieve high-resolution imaging. However, the influence of speckle noise and other additive noise will pollute the image, and the higher sidelobe level will cause more artifacts, poor resolution, and lower...
