Description

Magnetic resonance mammary gland imaging auxiliary device based on flexible coil

Technical Field

The utility model relates to the technical field of medical detection instruments, in particular to a magnetic resonance breast imaging auxiliary device based on a flexible coil.

Background

The breast nuclear magnetic resonance examination is often used for the condition of the diagnosis of the pathological changes of the breast, the stage of breast cancer and the like, and can intuitively know whether the breast has abnormality in the aspects of structure, function and the like.

Clinical breast nuclear magnetic imaging requires that the breast be in a fully extended state of overhang and relatively unchanged and stable in spatial position and morphology, so that a special breast coil and prone position are adopted for data acquisition of an examinee. In the prone position, the head is advanced, and the bilateral breasts naturally hang at the center of the breast coil. When the breast is positioned, all breast tissues are required to be positioned in the coil, the skin and the breasts are not wrinkled, the breasts on two sides are symmetrical, the nipple is vertical to the ground, and the central line of the breastbone is positioned on the central line of the coil.

In order to solve the problem of fitting degree, a breast coil positioning, scanning and imaging method such as 202011060660.0 appears on the market at present, and the adaptability of the breast coil to different individual characteristics is improved by adjusting the positions of the two fixing plates and the angle of the coil plate by utilizing the turntable, so that the problem that the adaptability of the existing breast coil is poor and the imaging quality is influenced is solved.

However, the above-mentioned device still has problems in practical application, and the applicant believes that the existing breast coil has a fixed cavity size for placing the breast, and is difficult to adapt to the examiner with all the sizes of the breast. When the volume and breast of the inspector are too large, the cavity is difficult to accommodate for imaging; when the volume of the examiner and the breast are too small, a large space is left between the breast and the coil, the collection performance of the coil signals is affected, and the signal intensity, uniformity and signal-to-noise ratio of the image may be significantly reduced.

Whereas the conventional coil is free of coil signal detection units at the left side, right side and middle of the breast of the examinee, which makes the signal collection at both sides of the breast affected, possibly degrading the imaging performance and affecting the detection of lesions. The conventional breast coil is of a fixed structure design because the basic unit from which the coil is made is a conductive copper ring, the stiffness of which and tuning circuitry near the coil elements limit the shape design, physical volume, weight and stiffness of the conventional coil.
