Mammary gland volume ultrasonic imaging device and method

Abstract

The invention provides a mammary gland volume ultrasonic imaging device and method to achieve three-dimensional volume ultrasonic imaging of a mammary gland for facilitating examination and diagnosis of a mammary gland disease. The device is composed of a main machine body, a main machine frame and a probe mechanism. The probe mechanism can move up and down and / or rotate to perform longitudinal or transverse detection. The probe mechanism comprises a detection support, a compression fixing device and a detection scanning mechanism. Tissue of the detected mammary gland is clamped in the middle, a clamping device on the upper portion can move up and down, and a scanning device on the lower portion is provided with an ultrasonic probe and a movement mechanism. In the process of primary imaging, the ultrasonic probe completes scanning on the detected mammary gland and obtains position data and an ultrasonic sampling image at each moment in the scanning process, an ultrasonic section image set containing position information is obtained through image processing, and a three-dimensional image is reconstructed according to the ultrasonic section image set to complete three-dimensional volume ultrasonic imaging of the tissue of the mammary gland.

Description

technical field [0001] The invention relates to the technical field of ultrasonic diagnosis, especially breast ultrasonic scanning, medical image processing and reconstruction, in particular to a breast volume ultrasonic imaging device and method. Background technique [0002] Mammography is a commonly used breast imaging detection method in the prior art. Imaging is simple and reproducible, and is currently the gold standard for breast cancer detection. However, mammography has X-ray radiation, requires a special protective environment, and is not effective for dense breast examination. Studies have shown that for dense breast tissue, mammography reports a sensitivity of 44%. dense breasts (i.e. BI-RADS TM Breast density of 3 or 4) is common in young women, while compared with Western women, Eastern women have relatively dense breasts, and the age of onset of breast cancer is lower. So other testing equipment is needed. [0003] In addition, magnetic resonance imaging ...

Problems solved by technology

Clinically, doctors need to spell out the three-dimensional structure of breast tissue in their minds based on real-time two-dimensional images, which requires doctors to have very rich clinical experience and long-term training, which is easy to produce inaccurate information about the location, shape and size of tumors In the follow-up ultrasound examination, according to the previous two-dimensional ultrasound image, it is difficult for the doctor to locate the image obtained by the previous examination, and it is also difficult to obtain the ultrasound image of the same position repeatedly, which is very important for the long-term follow-up observation of the lesion.
