MR imaging and intervention functions are localized within a single device. At least one integrated coil device (62,63,64,90) which has at least one RF coil (72,94,112,118), a housing (70,74,92,96,110,114) which encases the RF coil and provides an anatomically conformal surface, and a plurality of apertures. The integrated coil device slides along a guide rail system(66) to adjust the size of a patient anatomical imaging region (60). The apertures in the integrated coil device are available to secure tool holder grid plate inserts (67,116,130,131) or other interventional device guides. The inserts assist in holding the soft tissue for diagnostic imaging and provide support for biopsy/interventional instrument guides(140). The integrated MR imaging and interventional coil device works in combination with a prone patient support structure(20), an adaptive torso sling(55), and also features an open architecture design for improved patient access. The device also works for supine or side imaging procedures.

Integrated mr imaging and interventional coil device, method and system

The invention discloses a multichannel radio frequency coil device for an NMR imaging system, comprising an inner housing and a coil part; the coil part covers and is attached on the inner housing; the inner housing is of an shoe shape; the inner housing comprises a shoe cylinder part, a vamp, an upper, a shoe sole front end part, a shoe sole middle portion, and a shoe sole rear end portion The beneficial effects of the invention are that the coil can completely cover the whole foot part, has a relatively big uniform area and a high signal to noise ratio, and is good in imaging

Multichannel radio frequency coil device for NMR imaging system

The invention discloses a breast magnetic resonance radio frequency receiving coil used for a magnetic resonance imaging system. The breast magnetic resonance radio frequency receiving coil comprises an outer shell assembly and an antenna circuit arranged inside the outer shell assembly. The outer shell assembly comprises a base plate component and a baffle component which is used for attaching to a human body. Two through holes used for placing breasts are formed in the baffle component. A plurality of connecting columns are arranged between the base plate component and the baffle component. Two imaging spaces in an open type structure are respectively formed among the base plate component, the connecting columns and the through holes, wherein the imaging spaces are used for containing the breasts of a patient. The antenna circuit comprises a plurality of coil receiving units which are respectively wrapped and wounded on the outer sides of the imaging spaces and form a multi-channel phased array structure. The breast magnetic resonance radio frequency receiving coil can satisfy the demands of breast biopsy guided by magnetic resonance, is beneficial for improving scanning coverage range and image quality of underarm lymph and breast wall tissue in breast magnetic resonance scan, and has the advantages of being high in signal to noise ratio, wide in coverage range, high in imaging quality, convenient to use, and simple in structure.

The invention discloses a breast parallel-scanning coil. The breast parallel-scanning coil comprises a plurality of coil units, wherein the coil units are arranged along the outer contour of a left cup and the outer contour of a right cup respectively, the left cup and the right cup are arranged symmetrically, and each coil unit is insulated to form an independent measurement channel. According to the breast coil with the multiple channels, the cups which are used for covering the left breast and the right breast are formed by the coil units which are arranged up and down, front and back and left and right, and due to the fact that the coil units are distributed on all space where the breasts are located, signals in all directions can be collected, a higher signal to noise ratio can be obtained, and at least parallel connection of factors 2 is available in all directions. In addition, decoupling is achieved through inductors, capacitors and overlapping, the signal to noise ratio is further improved, and quality of a collected image is improved.

Breast parallel-scanning coil

The invention relates to an adaptive breast magnetic resonance imaging coil The adaptive breast magnetic resonance imaging coil is characterized by at least comprising a breast bracket (1), wherein the breast bracket (1) is of a cavity structure; the lower end of the cavity is provided with a left coil (2) and a right coil (3); the left coil (2) and the right coil (3) are fixed to the left and right positions at the bottom of the breast bracket (1); the left coil (2) and the right coil (3) are in center superposition with a left breast suspension hole (4) and a right breast suspension hole (5) of an upper cavity The adaptive breast magnetic resonance imaging coil meets requirements of different users when used for breast examination through magnetic resonance imaging

Adaptive breast magnetic resonance imaging coil

The invention relates to a breast radio frequency coil device, especially relates to a level field four-coil radio frequency coil device The invention provides a breast radio frequency coil device, including a supporting case, having a bottom surface and a skin covering, wherein the bottom surface has two convex spheres which are eudipleural, and the skin covering is covered on the sphere; and two coils arranged inside the supporting case, wherein each group of coil has an annular coil and a splay coil, and the annular coil is covered on the sphere, while the splay coil is turned over in opposite direction using the crossing as the peak to form a coil with the saddle shape The coil with the saddle shape is covered on the sphere, having the bottom churned up outwards, to form a raised edge, wherein the raised edge is adhibited on the bottom surface The invention has the advantages of good uniformity, high SNR and high detection sensitivity etc
