Abstract: A method for generating transmission information in a time-of-flight positron emission tomography (PET) scanner having a patient tunnel and a plurality of PET detector rings. The PET scanner uses continuous bed motion to move a patient bed and patient through the patient tunnel. The patient receives a positron-emitting radioisotope dose prior to undergoing a PET scan. The method includes storing a positron-emitting radioisotope in a radiation shielded container. The method also includes moving the radioisotope into a stationary vessel located adjacent to the PET detectors and within a field of view of the PET scanner at substantially the same time that the patient receives the radioisotope dose to form a stationary transmission source wherein transmission information is generated while the bed undergoes continuous bed motion. Further, the method includes withdrawing the radioisotope from the vessel when the PET scan is complete and storing the radioisotope in the container.

Abstract: The invention comprises a two-step process for analysis of polynucleotides by chain extension of multiple polynucleotide primers attached to solid supports by first performing PCR of the samples in the presence of multiple oligonucleotides in solution, the oligonucleotides of both sets being similar or identical. This produces immobilized single-strand polynucleotides containing genetic sequence data derived from sample molecules. In a second step, support-bound polynucleotides are interrogated by hybridization with a single labeled oligonucleotide probe or by second-strand synthesis with a primer-dependent polymerase using an oligonucleotide primer and nucleotide monomers, in which either or both of the primer and nucleotide monomers are labeled. Incorporation of label demonstrates the presence of two separate defined-sequence primers within the sample polynucleotide.

Abstract: A method for combined computed tomography (CT) imaging and positron emission tomography (PET) imaging uses respiration-gated CT imaging in which the optimal criteria for CT scan gating are determined after the PET scan has been performed. After acquisition of first CT scan image data and PET scan image data with strain gauge levels being recorded, optimal gating criteria are calculated based on the strain gauge levels, and a second CT scan is then performed with triggering in accordance with the optimal gating criteria.

Abstract: A method for performing accurate iterative reconstruction of three dimensional image data sets based on Approximate Discrete Radon Transformation (ADRT) using two dimensional linograms for each of a plurality of defined planes tilted from the (x, y, 0) plane by a tilt angle and orientation angle. Image data is arranged with respect to the defined tilted planes ADRT and its inverse are implemented to provide exactly matched forward and backward projectors suitable for the Maximum-Likelihood Expectation-Maximization (ML-EM) reconstruction in PET. An EM reconstruction algorithm is accomplished by initializing an estimation image.

Abstract: Disclosed is a method and Declarative Web Application (DWA) for creating an abstraction layer between a web page and the complicated syntax required to access data to display on the web page. The abstraction layer is implemented with eXtensible Markup Language (XML) tags that permit a web page using simple, non-compiled custom XML tags embedded in Hyper Text Markup Language (HTML) formatting commands to call complex data storage and search engine queries using a simple, declaratory statement via a XML tag. Use of the simple, declaratory XML statement removes the need for any scripting or other complex code from the web page that may require compilation and/or extensive verification testing for changes to the web page code. The resulting web pages and query definitions are easier and less expensive to maintain and extend.

Abstract: An apparatus for detecting a greater number of lines of response (LOR) within a subset of azimuthal angles of a positron emission tomography scanner. In a positron emission tomography (PET) scanner, the detectors are configured to detect a greater number of lateral LORs than the number of anterior/posterior LORs passing through a patient. The increased sensitivity to the lateral LORs compensates for the increased distance that the lateral LORs travel through the patient than the anterior/posterior LORs. In one embodiment, at least one pair of partial rings are positioned adjacent fixed detector rings. In another embodiment, panel detectors with a longer length than the other detectors are positioned to be responsive to the lateral LORs. In still another embodiment, detectors rotated with a variable angular speed, spending more time measuring lateral LORs than measuring anterior/posterior LORs.

The method includes identifying pixels in a CT image having a large HU value, identifying a region surrounding the pixels, and modifying a value of each pixel within the region.

Abstract: The invention comprises a two-step process for analysis of polynucleotides by chain extension of multiple oligonucleotide primers attached by 5′-linkages to solid supports by first performing PCR of the sample to be analysed in the presence of multiple oligonucleotides in solution, the nucleotide sequences of both sets of oligonucleotides being similar or identical. This produces immobilised single-stranded polynucleotides containing genetic sequence data derived from sample molecules. In a second step, support-bound polynucleotides are interrogated by hybridisation with a single labelled oligonucleotide probe or by second-strand synthesis with a primer-dependent polymerase using an oligonucleotide primer and nucleotide monomers, in which either or both of the primer and nucleotide monomers are labelled. Incorporation of label demonstrates the presence of two separate defined-sequence primers within the sample polynucleotide.
