Abstract

PURPOSE:To obtain accurate reconstituted data and to shorten data collection time, by controlling the data collection time according to the shape of an object to be tested. CONSTITUTION:Information of an object 1 to be tested from a detector 5 is supplied to a data processor through a data collection interface 7. Part of the data is fetched into a high-frequency component computer 12, which performs prescribed calculation to return the resulting information F to the processor 8. The processor 8 discriminates the shape of the object by the magnitude of the information F. Namely, when the value is small, the shape is considered to be simple to minimize the data collection time, and when large, it is considered to be complicated to extend the data collection time. Thus, the data collection time is controlled according to the shape of the object, and consequently while accurate reconstituted data is obtained, the data collection time is shortened.
