A technique is provided for sharing clinical protocols for diagnostic imaging systems. The clinical protocols generally represent operational parameters, such as configuration data and procedures, which are clinically developed for a particular imaging diagnosis. An interface or access point, such as a network accessible database or website, is provided to facilitate the exchange of these clinical protocols between clinicians. The present technique also may facilitate the formation of new clinical protocols and/or the integration of new clinical protocols into various diagnostic imaging systems. Accordingly, clinicians can electronically exchange and configure a variety of imaging protocols for potentially greater quality in the particular imaging diagnosis.

Method and system for transfer of imaging protocols and procedures

The present invention includes a filtering apparatus for a CT imaging system or equivalently for an x-ray imaging system. The filtering apparatus may be translated along a first axis or a transverse axis to with respect to an attenuation pattern of a subject during an imaging session to reduce radiation exposure to anatomical regions of the subject sensitive to radiation exposure and/or regions from which data is not being acquired.

The present invention relates generally to MR imaging and, more particularly, to a method and apparatus for reconstructing zoom MR images. An RF coil assembly having a number of detection elements is provided. The RF coil assembly is designed such that the number of detection elements that may be used to acquire imaging data may exceed the number of data acquisition channels of the MR system. Accordingly, the detection elements may be grouped into a number of sets wherein each set transmits acquired data to a specific data acquisition channel to acquire data of a larger region-of-interest (ROI) or, alternately, only one set of detection elements corresponding to a smaller ROI may be activated wherein each detection element of the set transmits data to a data acquisition channel. As a result, a zoom image may be reconstructed.

An MRI system is provided with normal and quiet modes of operation. The quiet mode may be selected from an operator station, such as via a graphical user interface. When the quiet mode of operation is selected, configuration parameters are used for the particular pulse sequence to be executed in the examination. The configuration parameters for the quiet mode of operation may be derived from those of the normal mode of operation. The quiet mode of operation may, for example, employ gradient pulses having reduced amplitudes and slew rates as compared to those employed in the normal mode of operation. The reduced amplitudes and slew rates, along with changes in timing of the pulses and between pulses of the pulse sequence of the examination result in reduced acoustic noise for accommodating more sensitive patients.

Quiet mode magnetic resonance imaging system and method

An MRI system acquires MRA data from two overlapping thin slabs using a 3DTOF pulse sequence. Motion artifacts are reduced by using a reverse centric phase encode order during the first thin slab acquisition and a centric phase encode order during the second thin slab acquisition. Patient movement is reduced by producing a uniform sound with gradient pulse sequences during the interval between thin slab acquisitions and during a preparation period prior to the first thin slab acquisition.

Reducing image artifacts caused by patient motion during MR imaging

Fast NMR pulse sequences are employed to acquire data sets from which a set of images can be reconstructed depicting a patient's heart at successive phases during the cardiac cycle. The number of images is increased by selecting views from adjacent data sets to form interpolated data sets that are employed to reconstruct images depicting the patient's heart at cardiac phases between the successive phases.
