Problems solved by technology

[0005] The existing technology uses an external ultrasonic image processing module to process the ultrasonic image again, and its main disadvantage is that it must rely on an external ultrasonic image processing module to complete the processing; and the prior art uses a video acquisition card for ultrasonic diagnosis When the video signal of the ultrasonic diagnostic instrument is collected as the data source for the reprocessing of the ultrasonic image, the image data of the ultrasonic diagnostic instrument has undergone a D / A conversion before being converted into a Video or S-Video signal output, and then in the video acquisition card. After an A / D conversion, the digital signal is transmitted to an external ultrasonic image processing module, such as a PC (Personal Computer, personal computer) for processing, and the processed data needs to undergo a D / A conversion again
Therefore, using an external ultrasonic image processing module for image processing requires one more D / A conversion and one A / D conversion compared to the ultrasonic diagnostic instrument, which will inevitably cause the loss of effective image data and directly affect the reprocessed image.

Abstract

The invention discloses an image processing apparatus and an ultrasonic diagnostic device, the image processing apparatus comprises a data acquisition module, a data buffering module, an interface control module, a processor and an ultrasonic image processing module; the data acquisition module acquires image data under control of the processor and stores the acquired image data into the data buffering module, the image data in the data buffering module is transmitted to the ultrasonic image processing module by the interface control module to be processed, the processed image data can be output by the interface control module. The image processing apparatus provided by the invention can perform three-dimensional imaging and wide radial imaging or the like for the ultrasonic image data; can avoid loss of the effective image data when the ultrasonic diagnostic device uses an external image processing module, can ensure the image effect after processing the ultrasonic image again, thereby improving the accuracies of the detection and the analysis by using the ultrasonic diagnostic device.

Description

technical field [0001] The invention relates to image processing and medical equipment, in particular to an image processing device and an ultrasonic diagnostic instrument. Background technique [0002] Ultrasound imaging has the advantages of non-invasive, non-destructive, and non-ionizing radiation, and has been paid more and more attention by people. On the basis of the direct imaging of the ultrasonic diagnostic instrument, it is often necessary to reprocess the ultrasonic imaging data to achieve more advanced functions, such as three-dimensional imaging, wide-diameter imaging and other functions. The current ultrasonic diagnostic instrument itself does not have the function of ultrasonic image reprocessing, and must rely on an external ultrasonic data processing module. This data processing module is completely separated from the ultrasonic diagnostic instrument in structure and works independently of the ultrasonic diagnostic instrument. [0003] At present, the gener...
