    摘要: A magnetic resonance imaging system to be used over a target area of a subject includes first and second RF coils for receiving an RF signal from the subject. The first RF coil is fixed to a position device and movable over the target area of subject. The second RF coil is larger than the first RF coil and has a larger field of view than the first RF coil. The system further includes an image processing device programmed to process RF signals coupled from the first RF coil and the second RF coil to form an MRI image.

    摘要: Systems and methods are provided for positioning a therapeutic device relative to a target displaced on a platform. A base member has a first track extending along a length of the platform for defining a first pathway for translating the therapeutic device relative to the target. A curved frame is slidably mounted on the base member through the first track. The curved frame has a second track along an interior wall of the curved frame for defining a second pathway for translating the therapeutic device relative to the target. A housing is disposed in the second track of the curved frame and configured to receive the therapeutic device. The housing is extendible at least along a radial direction of the curved frame for defining a third pathway for translating the therapeutic device relative to the target. Applications of the systems and methods may include image-guided thermal therapy.

    摘要: An MRI imaging system provides an audible feedback signal in the gantry room triggered by a physiological sensor on the patient. The feedback signal is a sound generated by one of the MRI gradient coils. The sensor output signal may be indicative of the patient's heartbeat, or other physiological event. The application of the sequence causes the coil to emit a sound that is associated with the sensor output signal.

    摘要: A single sequence for the formation of a plurality of images of the same selected nuclei but with each image having a different contrast characteristic is disclosed. MRI signals are acquired during the first time interval which comprises a plurality of first intervals with each of the first intervals being substantially the same. During the first time interval, the selected nuclei are phase encoded by a different magnetic phase encoding gradient. The sequence continues to acquire a second plurality of MRI signals from the same plurality of selected nuclei. The second time interval comprises a plurality of second intervals different from the first intervals. During the second interval, the selected nuclei are phase encoded by a different magnetic phase encoding gradient but with the magnetic phase encoding gradient being the same as or a subset of those during the first time interval. The data from the first and second plurality of MRI signals are regrouped and portions are reused to form a plurality of regrouped data sets. Each of the regrouped data sets is then fourier transformed to produce a plurality of images of the selected nuclei. Each image is of the same plurality of selected nuclei but with different contrast characteristics.

    摘要: A medical system and method for treating a disorder of a subject by thermal ablation, e.g., focused ultrasound thermal ablation, are provided. The method includes obtaining medical images that include at least one image of subject's chest and ribs to reconstruct a three-dimensional chest-rib distribution; and applying ultrasound waves on a target point beyond the subject's ribs by selectively activating one or more elements of an ultrasound phased array to avoid ultrasonic energy absorption or reflection by an intervening rib based on a calculation of a relationship between the three-dimensional chest-rib distribution and an acoustic emission direction.
