Abstract: The amino acid sequence is deduced by using de novo sequencing, to prevent the correct amino acid sequence from not being ranked high as candidates. Amino acid sequence candidates are computed by finding the longest path by a branch and using a bound method based on the spectrum data on the target peptide and the known amino acid sequence. A tree-structured directed graph is used where amino acid sequences are set as nodes and the peak intensities corresponding to the amino acids are set as branches. In a sequence put at a node in the highest layer, an amino acid is placed at a terminal, and as the layer goes deeper, amino acids are sequentially placed from both terminals toward the center of the sequence. The final score is estimated based on the remaining amino acids, and if the score is small, the search is halted.

Abstract: All data obtained from an A/D converter during a summation period with values exceeding a prescribed threshold is excluded from summation up to a prescribed maximum number of deletions, and the values of the remaining data are summed to find one piece of measurement data corresponding to that summation period. The number of pieces of noise data reflecting the influx of particles that cause spike-like noise is extremely small, so noise data is removed in a state in which there are no signals and no target ions are present. When target ions are present, legitimate data which is not noise data may be removed, but the number of pieces of removed data is small in comparison to the total number of pieces of data, so the effects of the removal of legitimate data essentially do not emerge in the summation results. It is therefore possible to effectively reduce spike-like noise.

Abstract: Provided is a technique for calculating a hole depth or substrate thickness with high accuracy during surface processing work, such as etching or grinding. A difference spectrum calculator calculates the difference between a spectrum acquired at one time and another spectrum acquired at a time earlier than the aforementioned time by a predetermined. The base spectra which are contained in the observed spectra but do not contribute to interference can be regarded as common to the observed spectra. Therefore, the difference spectrum is a virtually normalized interference spectrum. A Fourier transform operator performs a frequency analysis on the difference spectrum, using a Fourier transform or similar technique. In the thereby obtained signal, a clear peak originating from the interference appears at a position corresponding to the optical path length. From this peak position, an optical distance calculator determines the optical path length, calculates the hole depth, and displays the calculated result.

Abstract: Provided is a radiation tomography apparatus that performs radiography for a series of fluoroscopic images while moving a radiation source and a radiation detecting device synchronously in opposite directions to each other and obtains a tomographic image of a subject based on the fluoroscopic images. The radiation tomography apparatus allows to preview the tomographic image obtained through the radiography immediately after completion of the radiography. A preview image for previewing a sectional image of a subject is generated besides a tomographic image for diagnosis. The preview image can be obtained through simpler computing processing. Consequently, an operator sees once the preview image displayed on a display unit prior to the tomographic image for diagnosis, thereby determining to conduct radiography again quickly.

Abstract: Provided is a method for quantitatively estimating the probability of substance identification based on the result of an MS2 analysis using a certain MS1 peak as the precursor ion, before performing the MS2 analysis. Based on the result of MS1 and MS2 analyses and substance identification performed for each of a number of fractionated samples obtained from a known preparatory sample, an identification probability estimation model creator grasps m/z and S/N ratios of MS1 peaks having high probabilities of successful identification, calculates a parameter which determines the order of MS1 peaks and a parameter representing an identification probability estimation model, and stores the parameters in a memory. When identifying a substance, an approximate order is calculated for an MS1 peak obtained by the analysis. The identification probability for that peak is estimated from the approximate order with reference to the identification probability estimation model.

Abstract: Provided is a technique for accurately identifying a peptide even if the peptide cannot be identified by MS/MS ion search or de novo sequencing. The technique uses an MSn spectrum for a low m/z precursor ion. Such a spectrum contains a rather small amount of information, but this information is highly reliable when used for deducing an amino acid sequence by de novo sequencing. Accordingly, an MSn spectrum for a precursor ion having an m/z value of 500 or less is intentionally obtained, and de novo sequencing is performed on this spectrum to deduce the amino acid sequence covering the range from the m/z of the precursor ion and m/z=0. A highly reliable sequence tag can be generated from the deduced amino acid sequence, the m/z of the precursor ion of the MSn analysis, and the m/z of the precursor ion of the MS2 analysis.
