Magnetic resonance cervical coil

Abstract

The invention provides a magnetic resonance cervical coil which comprises a rotating bottom cover, a sliding rod, a body, a first rotating rod, a second rotating rod, a third rotating rod and a cylindrical surface circuit. External threads are arranged on the outer side of the top of the rotating bottom cover, a groove is formed in the bottom of the body, internal threads matched with the externalthreads are arranged on the inner wall of the groove, through holes for containing the sliding rod is formed along the center of the groove, a first rotating rod is hinged to the top of the body, thefirst rotating rod is further hinged to the second rotating rod, a coil on the lower surface of the cylindrical surface circuit penetrates through the through hole formed in the second rotating rod,a preset position between the two ends of the second rotating rod is hinged to a first position of the top of the sliding rod, one end of the third rotating rod is hinged to a second position of the top of the sliding rod, the second position is higher than the first position, and a radio frequency coil on the upper surface of the cylindrical circuit penetrates through the through hole formed in the other end of the third rotating rod, so that the imaging quality can be improved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a magnetic resonance cervical coil. Background technique [0002] With the rapid development of magnetic resonance imaging technology, its application is becoming more and more extensive. For example, because women's cervical tissue has a variety of possible lesions, including cervical cancer, cervical erosion, etc., therefore, magnetic resonance imaging technology can be applied to women detection of cervical tissue lesions. With the help of magnetic resonance imaging technology, doctors can obtain more clinical information of the cervical and surrounding tissues to support diagnosis and treatment. Among them, the magnetic resonance cervical coil is an indispensable tool in magnetic resonance imaging technology. In clinical applications, the magnetic resonance cervical coil is required to be light, easy to use and reliable. On the premise of ensuring uniform imaging, it...

AI Technical Summary

Problems solved by technology

However, after the built-in cavity type magnetic resonance cervical coil is inserted into the cervix, paracervix, fornix, sacral ligament and other cervical parts, the space formed by these parts is much smaller than the space formed by the parts just inserted. Larger, the gap between the coil probe and these parts increases, resulting in a low signal-to-noise ratio of the induced imaging signal, resulting in poor imaging quality, which cannot meet the needs of diagnosis and treatment
