    Abstract: A method of extracting at least one time-value curve to determine a protocol in an imaging procedure using an imaging system, includes: determining a first N-dimensional data set of pixel values of a portion of a body of the patient at a first time using the imaging system, wherein N is an integer; determining at least a second N-dimensional data set of pixel values of the portion at a second time using the imaging system; computing a predetermined number of correlated segments of the imaged portion corresponding to a predetermined number of regions of interest of the patient by computing a similarity metric of a time series of pixel values; computing the at least one time-value curve for at least one of the regions of interest; and determining a protocol for a diagnostic scan using the image system based at least in part upon data from the time value curve.

    Abstract: A magnetic resonance imaging receiver/transmitter coil system for providing images for regions of interest includes a first phased array formed of a plurality of electrically conductive members and defining an array volume and a second phased array formed of a second plurality of electrically conductive members and disposed at least partially within the defined array volume. At least one of the first and second phased arrays is adapted to apply a magnetic field to the defined array volume. At least one of the first and second phased arrays is further adapted to receive said applied magnetic field. The first phased array is extendible to define a further array volume and is provided with a switch for electrically coupling and decoupling an extension to effectively extend the length of the first phased array and thereby define the further array volume. In this manner the length of the first phased array is effectively extended to approximately twice its unextended length.

    Abstract: A fluid delivery system for use in medical procedures includes multiple fluid pump devices to deliver multiple injection fluids to a patient. The system includes a control unit controlling the fluid pump devices. An interactive visual display may be provided and electronically linked to the control unit so a user may select discrete mixture ratios of the first and the second of the multiple injection fluids to be delivered to the patient. A manual control device is operatively associated with the fluid pump devices and includes a housing and an actuator associated with the housing. Actuation of the actuator controls discrete flow rates of the selected discrete mixture ratio of the first and the second of the multiple injection fluids to the patient.
