Problems solved by technology

In this way, the diagnosis results are very subjective, which is easy to cause misdiagnosis and missed diagnosis; at the same time, the outline of the lesion area is mainly drawn by the doctor manually, which is time-consuming and laborious, and the reproducibility of the results is poor.
At present, the research on the processing methods of ultrasound images of space-occupying lesions at home and abroad is still in its infancy.

Embodiment Construction

[0045] The method for processing ultrasound images of space-occupying lesions provided by the present invention aims to overcome the disadvantages of current clinicians' over-reliance on experience when diagnosing space-occupying lesions by ultrasound, so that the diagnosis results are extremely subjective.

[0046] See figure 1 , figure 1 It is a schematic flow chart of an ultrasound image processing method for a space-occupying lesion of the present invention. As shown in the figure, the technical solution of the present invention is to preprocess the collected ultrasound images, including removing text information around the image, filtering, border enhancement, determining effective information areas, etc.; then automatically positioning the lesion area and determining the occupying lesion Use the rough contour as the initial contour of the active contour model algorithm to extract the precise contour of the lesion area. The process includes the following steps:

Abstract

The invention discloses a processing method for space-occupying lesion ultrasonic images. The processing method preprocesses the acquired ultrasonic image, comprising the following steps: the removal of the text information around the image, filtration, edge enhancement, the determination of an effective information region and the like; automatic location of a lesion region; determination of the rough contour of the space-occupying lesion, and extraction of the precise contour of the lesion region with the rough contour as an initial contour for an active contour model algorithm. The processing method realizes the functions of automatically segmenting the space-occupying lesion ultrasonic image and automatically extracting the region of interest in order to automatically diagnose the space-occupying lesion, thus enhancing the objectivity and accuracy of clinical diagnosis, and therefore the processing method effectively assists the diagnosis of space-occupying lesions.

Description

Technical field [0001] The invention relates to the field of ultrasound images, in particular to a technology for processing ultrasound images of space-occupying lesions. Background technique [0002] Cancer is a general term for a large class of malignant tumors. There are often few symptoms in the early stages of cancer, and a series of symptoms and signs gradually appear after a certain stage. At this time, it is often too late to take treatment measures. Therefore, early diagnosis and early treatment of cancer are particularly critical. At present, the main methods for early diagnosis of cancer include alpha-fetoprotein measurement, ferritin detection, ultrasound examination, CT examination, magnetic resonance imaging, selective contrast examination and so on. Among them, ultrasonography has the characteristics of non-invasive, non-radiation, low price, real-time, repeatable operation and easy operation, and has become one of the main methods for early cancer diagnosis.
