Description
Technical field
This application involves a kind of horizontal magnetic resonance intervention special-purpose radio-frequency array coil device and its application methods.
Background technique
Magnetic resonance system is a kind of high-end medical imaging devices, it can be divided into level field according to the magnetic direction of main magnet
Magnetic resonance system and perpendicualr field magnetic resonance system.Horizontal field system refers to that the magnetic direction of magnet is parallel with the trunk of people, from
Brain is directed toward sole or opposite.Vertical field systems refer to that the magnetic direction of magnet is vertical with the trunk direction of people, such as from people
Front be directed toward the back side.Magnetic direction is the design most important reference frame of radio-frequency coil, because the antenna element in coil needs
It is vertical with magnet direction as far as possible, best radio-frequency drive or receive capabilities could be obtained.From the performance of radio-frequency coil
For, clarity (i.e. sensitivity, or more popular saying signal-to-noise ratio) and uniformity are two most important measurement indexs.
Interventional radiology is also known as interventional therapy, is that one developed rapidly in recent years has merged diagnostic imaging and clinic
It treats in the new branch of science of one.It is the guidance in image documentation equipments such as digital subtraction angiography machine, CT, ultrasound and magnetic resonance
Under monitoring, using puncture needle, conduit and other interposers materials, by human body natural duct or small wound by specific device
Tool imports the general name that human lesion position carries out a series of technologies of minimally-invasive treatment.Have become at present with traditional internal medicine, outside
Section's big pillar subject of clinic three arranged side by side.Abdomen interventional radiology, mainly for each system of abdomen, organ, organ disease, packet
Include the Engaging in Intervention Radiology skill in ten thousand faces such as various pernicious and benign tumour, hemorrhagic lesions, wound, major abdominal vascular lesion
Art.
Magnetic resonance navigation intervention (Interventional MR) is a brand-new concept, now also in early-stage development
Stage.MR-guided interventional needs special technology and open radio-frequency coil.The operating method of MR-guided interventional, with corresponding X
