Patent number: 8159222Abstract: Accumulated spin magnetization phase within a RF MRI procedure can be used for providing an orderly k-space traversal. By operating a transmit array adapted to produce two B1 fields in alternation, where the B1 fields are substantially uniform in amplitude over a sample volume of the MRI setup, and the B1 fields have respective spatial phase distributions such that selection of a difference in spatial derivatives of the spatial phase distributions permits control over a size of a step in k-space applied by successive refocusing pulses for generating the B1 fields in alternation. Each alternating refocusing pulse issued within a T2 time causes a step through k-space in an encoding direction determined by the difference in spatial derivatives.Type: GrantFiled: May 2, 2008Date of Patent: April 17, 2012Assignee: National Research Council of CanadaInventors: Scott King, Jonathan Sharp

Publication number: 20100171499Abstract: Herein a method for slice selection is provided in an MRI process, the method involves controlling a transmit array by adding low flip angle RF pulses interspersed between refocusing pulses that are used to move a k-space weighting function with respect to one or more B 1 fields used to deposit energy according to a desired k-space weighting function. The low flip angle pulses deposit energy so that an envelope traced by the low flip angle pulses in the k-space weighting function is related to a desired spatially excited region of the sample volume, for example by a Fourier transform, if the phase encoding directions are linear axes that coordinatize the sample volume, and the B 1 fields have linear phase gradients.Type: ApplicationFiled: May 2, 2008Publication date: July 8, 2010Inventors: Jonathan Sharp, Scott King

Publication number: 20020163987Abstract: The invention considers the frequency distributions of singles, doubles and triple neutron emission events from a sample under assay. The count rates are equated to mathematical functions related to the spontaneous fission rate, self-induced fission rate, detection efficiency and &agr;,n rate with probability distribution assigned to each of those factors, the value of the product of all the probability distributions being increased to give an optimised solution and so provide a value of the spontaneous fission rate which is linked to the mass of the neutron source. The technique aims to provide increased accuracy and certainty compared with neutron coincidence counting based techniques.Type: ApplicationFiled: February 13, 2002Publication date: November 7, 2002Applicant: BRITISH NUCLEAR FUELS PLCInventors: John Paul Ronaldson, Robert Jonathan Sharpe

Patent number: 5035350Abstract: Presented is a method and apparatus for precision control of work fluids in a squeezable tube that has no surge of work material during the shut off closing of the tube which is accomplished by a compensator moving simultaneously and oppositely to the shut off member movement, each of the compensator and the shut off member having different stroke lengths and tube engagable surface areas which effectively keep the internal volume of the tube the same. The method and apparatus are useful standing alone, in coordination with precision positive displacement pumping under computer control which is also presented, and as a part of sequential or simultaneous movement of a valve/pump dispensing head coordinated with a stationary or movable work piece to provide exceedingly fine control dispensing. Suckback between dispensing shots is coordinated with shut off and movements of inlet, outlet and dispensing members to afford operator programmable dispensing with precision and without drip.Type: GrantFiled: August 22, 1990Date of Patent: July 30, 1991Assignee: Minnesota Mining and Manufacturing CompanyInventors: Russell E.
