    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.

    摘要： A transducer for use with a high intensity focused ultrasound medical system has transducer elements that are made from a piezocomposite material bonded together in turn with an adhesive. The elements are deployed along a surface of a geometric structure with two curvatures. The structure is a truncated curved cylinder. The transducer also includes electrodes, each of which is arranged on a corresponding one of the transducer elements for exciting the transducer elements to emit ultrasonic waves in response to electrical signals applied to the electrodes to steer the waves to form a common focus zone in a desired heating area.

    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.
