Abstract: An MRI system is provided that includes a physiological sensor used for gating the MRI system and an MRI control terminal wirelessly connected to the sensor. The physiological sensor is used to monitor a physiological parameter of a user, such as pressure pulse, and communicate data regarding the monitored physiological parameter to the MRI control terminal. The MRI control terminal processes the data received from the physiological sensor and determines whether a triggering condition on the data is met. When it is determined that the triggering condition is met, the MRI control terminal initiates the acquisition of a data set. The acquisition of the data set involves initiating a pre-programmed pulse sequence and acquiring RF signals emitted from the patient's tissue as a result of the execution of the pre-programmed pulse sequence.

Abstract: In one aspect, the present invention is a method for detecting spinal abnormalities using magnet resonance imaging. The method comprises positioning a patient in an upright posture in an imaging volume of a magnet resonance imaging magnet with the spine of the patient adjacent to an antenna and capturing magnetic resonance imaging signals from a first portion of the patient's spine using the antenna with the patient positioned in a first position. The method may further comprise adjusting the patient position along a substantially vertical direction to a second position and capturing magnetic resonance imaging signals from a second portion of the patient's spine using the antenna with the patient positioned in the second position.

Abstract: A calibration system for a pulsed phase-lock loop ultrasound measurement system comprising an apparatus having a compartment for holding a pressure sensitive liquid. The compartment has an opening by which a flow of the pressure sensitive liquid may be controlled. A sensor arranged relative to the compartment to receive ultrasonic signals that reflect off one or more inner surfaces of the compartment. The system includes a processing device for receiving an integrated error signal output by the sensor based on pressure changes of the pressure sensitive liquid responsive to a change in flow of pressure sensitive liquid between the source and the compartment.
