A system and method for generating preamplifier feedback in magnetic resonance imaging (MRI) systems are provided. A preamplifier arrangement for the MRI system includes a plurality of preamplifiers with each of the preamplifiers connected to a different channel of a multi-channel coil array of the MRI system. The preamplifier arrangement further includes a feedback network connected to each of the plurality of preamplifiers with each of the feedback networks configured to generate negative feedback at one or more oscillation frequencies.

System and method providing preamplifier feedback for magnetic resonance imaging

A system and method for breast imaging is disclosed. The system is constructed as a modular RF coil system for an MR imaging apparatus and includes a fitted coil former constructed to have a shape and size so as to substantially conform to a breast of a patient to be imaged and a receiver coil array positioned on the fitted coil former and having a plurality of receiver coils arranged to form a coil array. At least one of a size of each of the plurality of receiver coils and a number of the plurality of receiver coils is based on a size of the fitted coil former. Based on its coil arrangement and its proximity to the breasts of the patient to be imaged, the receiver coil array of the modular RF coil system is capable of receiving MR data for parallel imaging.

A dual-frequency coil array for a magnetic resonance imaging (MRI) system is provided. The coil array includes a first coil element having a pair of dual-frequency loop coils and a second coil element having a pair of dual-frequency loop coils. The coil array further includes at least one capacitive mesh configured to decouple the pairs of dual-frequency loop coils of the first and second coil elements.

Systems, methods and apparatus are provided through which a compact pod insertable into the rectum for Magnetic Resonance Imaging/Magnetic Resonance Spectroscopy (MRI/MRS) examination of the prostate and containing two receive coils, each connected to transmit blocking and pre-tuned trap circuitry which can be superimposed within the pod in close proximity, can, without either circuit interfering with the other, efficiently gather, for imaging and tissue analysis, radio frequency signals emanating from magnetically disturbed nuclei in prostate tissue.

Systems, methods and apparatus for an endo-rectal receive-only probe

A patient table includes a cradle for slidably receiving a board carrying a patient, a cradle supporting member for slidably receiving the cradle, a locker for preventing the board from sliding off the cradle, and a stopper for preventing the cradle from sliding off the cradle supporting member. A method of transferring a patient to an imaging system from a second table uses the patient table to move the board from the second table to the patient table to the imaging system. An RF coil system usable with the table includes a coil, a coil cable, an intermediate box for receiving the coil cable, and a system cable extending from the intermediate box and connected to the imaging system.

System, method and apparatus for surgical patient table

A patient table is disclosed. The patient table includes a cradle for linearly receiving and transferring a board comprising a top surface defined by a single plane for carrying a patient, a cradle supporting member for slidably receiving the cradle, a locker within the cradle for positioning the board and patient on the table, and for preventing the board from sliding off the cradle, and a stopper within the cradle for preventing the cradle form sliding off the cradle supporting member.
