  • Patent number: 7932486
    Abstract: During the structural analysis of a protein or peptide by tandem mass spectroscopy, a peptide ion derived from a protein that has already been measured and that is expressed in great quantities is avoided as a tandem mass spectroscopy target. A peptide derived from a minute amount of protein, which has heretofore been difficult to analyze, can be automatically determined as a tandem mass spectroscopy target within the real time of measurement. Data concerning a protein that has already been measured and a peptide derived from the protein is automatically stored in an internal database. The stored data is collated with measured data with high accuracy to determine an isotope peak. In this way, the process of selecting a peptide peak that has not been measured as the target for the next tandem analysis can be performed within the real time of measurement and a redundant measurement of peptides derived from the same protein can be avoided.

  • Publication number: 20060116583
    Abstract: In the event that images are acquired for multiple cross-sections (multiple phases) by a predetermined imaging mode in an examination under stress to a subject, images of the same phase acquired by the same imaging mode in an examination before stress to the subject is read and simultaneously displayed as reference images together with current images. The operator can bring the cross-sectional position in the examination under stress in correspondence to the position of the examination before stress by comparing the displayed reference images with the current image.
