International Classification:

G01V 3/00

US Classification:

324318

Abstract:

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.

International Classification:

A61M 25/00

US Classification:

600433, 600434, 600435, 604 9505

Abstract:

A biopsy needle has a central axis and includes one or more sensing regions, each sensing region formed by a plurality of sensing optical fibers located over a particular extent of said central axis and inside the outer shell of the needle. The sensing optical fibers are coupled to a wavelength interrogator. A steerable catheter has a central axis and outer shell, the outer shell coupled to a plurality of optical fibers in sensing regions and actuation regions, the sensing regions formed over particular extents of the central axis by bonding gratings to the inner surface of the outer shell, and the actuation regions formed by coupling optical energy into shape memory alloys bonded to the outer shell.

International Classification:

A61B 5055

US Classification:

600412

Abstract:

Temperature in frozen tissue can be measured from magnetic resonance signals from the frozen tissue based on spin-spin relaxation time (T2) or based on relative intensity of the magnetic resonance signals. Short echo times are required, and use of tailored RF pulses, non-Cartesian readouts, and multi-slice and 3D k-space acquisitions are preferably employed.

International Classification:

A61M 5/168
A61M 5/00

Abstract:

A method of monitoring a fluid injection procedure is provided. The method includes: disposing a sensor on a catheter, where the sensor is in proximity to a tip of the catheter; inserting at least the tip of the catheter into a patient; delivering a fluid to a location within the patient via the tip of the catheter; and automatically monitoring a sensor signal from the sensor while the fluid is being delivered. Reflux end-point detection using an electrical impedance sensor has been demonstrated in a phantom. Applications include embolotherapy and angiography.

Abstract:

A method for magnetic resonance imaging is provided that includes using a magnetic resonance imaging system to excite a field of view (FOV) for a target being imaged, using an excitation plan to limit the excited FOV to a relatively narrow band of magnetization, exciting multiple bands of magnetization simultaneously, applying phase encoding along a shortest FOV dimension, acquiring a signal from said simultaneously excited bands of magnetization, and reconstructing and outputting a target image from the acquired signal.
