Abstract: A point cloud data processing device includes: a point cloud data storage unit that stores a plurality of pieces of point cloud data measured at an arbitrary measurement time at a plurality of measurement positions in a three-dimensional space; and a merged point cloud data generation unit that generates merged point cloud data in a time-series order based on the point cloud data stored in the point cloud data storage unit, the merged point cloud data including the point cloud data corresponding to any one of the measurement times, location data indicating a location of a point when pieces of point cloud data measured before the measurement time were integrated in a time-series order, and reference data assigned to each piece of location data, for specifying the point cloud data including the point indicated by the location data

Abstract: A CT apparatus comprises: a gantry; a table on which a subject to be examined is laid; a sensor section for acquiring distance data for determining a distance between a body part to be imaged of the subject and the sensor section; a height-data generating section for generating height data containing data of a height of the body part to be imaged of the subject based on the distance data; and a detecting section for detecting said body part to be imaged based on the height data, wherein the sensor section has a field-of-view region RV representing a region in which it is possible to acquire the distance data, and the field-of-view region RV is defined so that a portion of the table on a side of the gantry falls within the field-of-view region RV and a portion of the table on a side opposite to the side of the gantry falls outside the field-of-view region RV.

Abstract: Compounds of formula (I): ##STR1## wherein: R.sup.1 represents a lower alkyl group selected from methyl groups and ethyl groups;R.sup.2 represents a hydrogen atom or a methyl group; andR.sup.3 represents a group selected from C.sub.1 --C.sub.5 alkoxy groups,and pharmaceutically acceptable acid addition salts thereof have valuable antibiotic activity and are suitable for oral administration. They may be prepared by a variety of synthetic routes.
