[Previous technology] Digital ultra-theta wave shirt inspection technology, because it is a non-invasive scanning processing operation, provides excellent security, so it is widely used in medical inspection tools, such as: pregnant women's delivery, breast, uterus, liver, Examination of kidney, heart, etc., as well as the screening of tumors in various organs and tissues. Although ultrasound imaging technology has the aforementioned advantages of safety and low cost, its picture quality (image clarity) is not as high as that of high-priced positron computed tomography ( pET), magnetic resonance imaging (MRI) and other imaging technologies, and whether the azimuth angle of the ultrasonic detector to scan the object is appropriate, it also seriously affects the quality of the target image. Take scanning of fetal ultrasound in the womb of a pregnant woman as an example. Amniotic fluid Many times, the problem of fetal image obscured by the mother's placenta is less serious, but when the amniotic fluid is insufficient, it is more likely to be affected by the position and angle of the ultrasound detector, which will cause the fetal image to be obscured by the placenta, thus affecting the diagnostic quality of the physician. The technology of cutting the object image area of the ultrasonic target has not been developed in the early stage, so that it cannot solve the target object shadow. 6594032 2㈠ video feed of the subject matter of the rhyme interference problem, and a serious impact on health-stick correctness and timeliness of diagnosis of shellfish man, for this problem, the solution should be provided. [Summary of the Invention] The main purpose of this month is to provide a method of two-cut image processing of digital ultrasonic targets, especially-a method of manually selecting a feature = image area as the target area to pass the target of the present invention. The image area cut processing method deletes the image around the target area, and only retains the selected two = images' to avoid the target object image from being easily disturbed and the advantage of improving the quality of the shirt image. The secondary-objective of the present invention is to provide an image-cutting processing method of a digital ultrasonic target. The method of cutting the target image area is to retain the image of the target area only, which can greatly reduce the storage space of the image database, and also make the image More efficient use of database storage. = Another purpose of Ming is to provide a method for cutting the image area of a digital ultrasonic target. This processing method is implemented by the following steps, sequentially through image reading / display means, image area edge curve generation means, and wheat === line generation. Steps, means of regional growth, means of deleting the target image area, and means of restoring the target area image method * to achieve the effect of reducing the image quality and reducing the storage space.

Delete the image outside the selected area (outside) and keep only the selected area 594032 :: mask = 2 The image of the low-frequency target is affected by noise and obscured by the surrounding image. ^^ »# Stomach & gt Those who are ineffective in improving the quality of ultrasound images. In addition, further processing (deleting unnecessary images) can also greatly reduce the magic of the movie 2 '. It is also conducive to improving the use efficiency of storage space (image resource library). As shown in Fig.-, The cutting process of the image area of the ultrasonic target of the present invention, the ultrasonic image reading and display module (1 1), the edge curve generating module (12) of the image area, the target Image area closed: line generation weight group (1 3), Γ5 * 4: ¾, and z /, .L area growth module (1 4), target image area outside image deletion module (1 5w ,, _ , And (1 5) and the ultrasonic target image storage module (16) are jointly constructed. When the target image cutting process is to be performed, the aforementioned ultrasonic image reading and display-mode, group (1 D is to the The ultrasonic image database at the top of the first picture (2 (η to obtain specific ultrasonic image data (known by the medical staff)), and it is not displayed on the computer screen of the computer or workstation. The user can use the mouse on the screen After selecting the specific target image_) range above, the module (12) is generated by the edge curve of the target image area, and the curve of the edge of the mouse movement track is recorded and stored. Then, the curve is generated by the closed curve of the target image area ( 13) 'Interpolate for non-continuous curves Perform the repair process 'convert the selected curve into a continuous closed curve, and secondly, through the area growth module (14)' to distinguish the curve area _ and the outside area, and then delete the module through the image outside the target image area (Work 5 ) 'Delete the image data divided into areas and retain only the image data within the area' Finally, the processed image is saved back to the ultrasonic image data through the ultrasonic target image storage module (Work 8 594032 6). In the library (2), the target image cutting process is completed, and the recovered image data is removed from the irrelevant image, and only the target object image is retained, which is not only less susceptible to interference and obscuration from the peripheral image. In addition to improving the image quality and easy diagnosis and treatment by medical personnel, the image storage space can be greatly reduced, which is a design with considerable application value.
