| 20100301862 | DUAL-FREQUENCY COIL ARRAY FOR A MAGNETIC RESONANCE IMAGING (MRI) SYSTEM - 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. | 12-02-2010 |

| 20110241683 | MULTI-CHANNEL BREAST MRI RADIO FREQUENCY RECEIVER COIL - 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. | 10-06-2011 |

| 20110248712 | SYSTEM AND METHOD PROVIDING PREAMPLIFIER FEEDBACK FOR MAGNETIC RESONANCE IMAGING - 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. | 10-13-2011 |
