Problems solved by technology

Floor space in inspection facilities (eg, hospitals) is expensive and only limited space is available
Also, additional work to be done by the MRI system manufacturer to separate the electronic components from the magnet structure also adds to the cost of the MRI system

Abstract

An integrated electronic system housing and magnet structure (12) for an imaging system (10) includes a housing (40) and a radio frequency shield (46). The housing (40) is coupled to the magnet structure (13) and contains imaging system support electronics (42). The radio frequency shield (46) is coupled to the housing (40) and prevents radio frequency interference of a radio frequency receiver coil (30) from the imaging system support electronics (42).

Description

technical field [0001] The present invention relates generally to magnetic resonance imaging (MRI) systems and assemblies. More particularly, the present invention relates to radio frequency shielding of MRI magnet structures with MRI system support electronics proximally and integrally connected therebetween. Background technique [0002] Current magnetic resonance imaging (MRI) systems include superconducting magnet structures that generate a temporarily constant primary magnetic field. A superconducting magnet is used in conjunction with a magnetic gradient coil arrangement that is pulsed in sequence to produce a controlled sequence of gradients within a static magnetic field during an MRI data collection sequence. The controlled sequence gradient runs through the entirety of the patient imaging volume (patient bore) to which one or more MRI radio frequency (RF) coils or antennas are connected. The RF coil is located between the magnetic gradient coil arrangement and th...
