A monitor unit () monitors positioning augmentation information for correction of satellite positioning errors, the positioning augmentation information being generated by an augmentation information generation device with use of a specified parameter value being a parameter value which is specified. In a case where an abnormality is detected in the positioning augmentation information by the monitor unit (), a selection unit () selects a reserve parameter value that is to substitute for the specified parameter value, from among a plurality of reserve parameter values being a plurality of parameter values that are different from the specified parameter value and commands the augmentation information generation device to use the selected reserve parameter value as a new specified parameter value.

[Problem to be Solved] To improve stability of automatic normalization of a bone scintigraphy image. [Solution] A preferred embodiment includes: creating a pixel value histogram of image data representing a bone scintigraphy image; setting a plurality of thresholds related to pixel values based on the pixel value histogram; calculating respective average pixel values for the set thresholds; arranging the calculated average pixel values in order from the largest value; and determining a reference value for normalizing the image data based on at least part of a set of the average pixel values arranged in the order. The determining the reference value includes: determining one straight line that approximates a region of small average pixel values out of the set of the average pixel values arranged in the order; and calculating the reference value based on the straight line.

Technique for normalizing scintigraphy image

The present invention aims at limiting the pressure loss and smoothly discharging water treated by ion exchangers to the outside of the apparatus. Ion exchanging apparatushas outer vesselthat has inner space; and ion exchanger supportthat separates at least a part of inner spaceinto upper spaceand lower spaceand that can support ion exchangers to be loaded in upper space. At least a part of an upper surface of the ion exchanger support is made from at least one screen which supports the ion exchangers and which has a flow path allowing water treated by the ion exchangers to flow into the lower space

CPUreads out the bloodstream associated values of target voxel of subject's standardized brain bloodstream images (step S). CPUsorts the bloodstream associated values in descending order (step S). CPUrejects bloodstream associated values that are ranked top 10% and bottom 40% (step S). When the subjects are 20 for example, bloodstream associated values of highest 2 subjects and of lowest 8 subjects are rejected. CPUcalculates and stores mean value and standard deviation of remaining bloodstream associated values after the rejection (step S). CPUcalculates mean value and standard deviation of bloodstream associated values for each voxel as target voxel (steps S, S, Sand S). Then, the alternative normal brain database of brain bloodstream image is obtained.

Device for generating alternative of normal brain database

An image processing method is provided as one for creating a fused image automatically and with high overlapping accuracy. An image processing method according to an embodiment of the present invention includes (a) a voxel normalization step of equalizing voxel sizes and numbers of voxels in respective effective fields of view of a first 3D image based on a plurality of first tomographic images obtained from an arbitrary part of a subject and a second 3D image based on a plurality of second tomographic images obtained from the same part, thereby creating a first normalized 3D image corresponding to the first 3D image and a second normalized 3D image corresponding to the second 3D image; and (b) a fused image creation step of creating a fused image, using the first normalized 3D image and the second normalized 3D image.
