An examination-item database storing a plurality of types of examination items capable of examining a predetermined disease and attributes of these examination items so as to correspond to one another is prepared, the degree of risk for the predetermined disease is calculated based on individual physical information, a criterion for selection of an examination item for examining the predetermined disease is generated in accordance with the calculated degree of risk, and an examination item having an attribute meeting the selection criterion is searched out from the examination-item database. In addition, the calculated degree of risk and the examination-item database are displayed so as to correspond to the predetermined disease. This makes it possible to perform the optimal examination for each individual in accordance with the degree of risk, thereby improving the efficiency of detection of a disease. Moreover, reduction of superfluous examinations makes it possible to reduce physical and psychological burdens imposed on a patient by examinations.

The sensitivity in detection in a depth direction of a living body and the overall signal-to-noise ratio of an apparatus are improved, whereby a distribution of current sources in the living body or a plurality of current dipoles can be inferred more accurately than they conventionally are. A pickup coil array is made by combining a plurality of types of pickup coils that are mutually different in at least one of the order of a differential and a base line. The plurality of types of pickup coils are mutually different in, for example, only the order of a differential or only a base line, and are arranged separately at different measurement points or arranged at the same measurement point. Included is a magnetic source inferring means for inferably computing information on magnetic sources in a living body or information on the distribution of magnetic sources on the basis of detection signals provided by the plurality of types of pickup coils. The magnetic source inferring means includes a means for compensating for the influence of magnetic crosstalk among the plurality of types of pickup coils.

A plurality of magnetic field measurement units are arranged near a patient, a current source distribution and/or a current dipole in the patient are estimated on the basis of plurality of magnetic field distribution data measured by the magnetic field measurement units within a predetermined period of time. In particular, the current distribution and the current dipole at the desired time within the predetermined period of time are estimated by using spatiotemporal magnetic field distribution data measured by the plurality of magnetic field measurement units within the predetermined period of time and correlation information of the spatiotemporal magnetic distribution data. The current distribution and the current dipole are estimated by using cross-correlation information of noise data measured by the plurality of magnetic field measurement units.

Flux of magnetic field generated from an object P of magnetic measurement, which links with the pick-up coils of the fluxmeters, where the flux is converted into electrical signals by each of the SQUID chips driven by the FLL circuits. The electrical signals are sent to the data collection unit via the signal processing circuit. In the data collection unit, the electrical signals are converted into digital data by the A/D converter. The converted digital data are recorded on a hard disk or a magnet-optical disk or the like, of the data recording section. The digital data recorded on the data recording medium are compensated with use of a crosstalk compensation matrix so as to remove the interference due to crosstalk for each channel, by the crosstalk compensation section. The compensated data are displayed directly on the display in the form of a magnetic field distribution or time waveform, and sent to the data analysis section. The data sent to the data analysis section are subjected to a process for obtaining a current source distribution of the living body or the like, and then displayed on the display.
摘要:
In consideration of the fact that a lung field varies in the density of sponge-like tissue depending on an individual or display region, an opacity curve which gives priority to a nodule candidate region or an extended nodule candidate region can be set by generating a histogram concerning a volume of interest which includes a foreground region, and using the statistical analysis result on the histogram as an objective index.

A reference landmark extracting and pairing unit extracts reference landmarks from each of two three-dimensional medical images and forms reference landmark pairs, while a general landmark extracting unit extracts general landmarks. The landmark pair forming unit forms general landmark pairs using of a distance between each of the reference landmarks and the general landmarks, and also forms general landmark pairs from the remaining general landmarks using the distances from the general landmarks included in the general landmark pairs. A coordinate transformation parameter calculating unit calculates coordinate transformation parameters, based on the positional information of the reference landmark pairs and the general landmark pairs. A corresponding sectional view creating unit creates corresponding sectional views for the two three-dimensional medical images based on the coordinate transformation parameters, and by the display controlling unit the two corresponding sectional views are displayed on a displaying unit.

摘要:
The extraction processor of the medical image-processing apparatus sets landmarks of each medical image based on volume data of two medical images. The positional relationship information-generating part generates positional relationship information that indicates positional relationship of the landmarks for each of the two medial images. The landmark-coordinating part eliminates one or more landmarks from each medical image based on the positional relationship information. Further, the landmark-coordinating part coordinates the landmarks of two medical images that remained after the elimination. The image-aligning part aligns the two sets of volume data based on the result of the coordination of landmarks.
