Title:
DIAGNOSTIC IMAGING APPARATUS AND IMAGE DISPLAY METHOD
Document Type and Number:
WIPO Patent Application WO/2013/105568
Kind Code:
A1
Abstract:
This diagnostic imaging apparatus is provided with: an image pickup unit that images a region of the subject and generates image data; a biosignal-acquiring unit that acquires biosignal data that is a periodic movement of the region of the subject; a storage unit that stores the generated image data synchronized with the acquired biosignal data; a biosignal analysis unit that analyzes the biosignal data and detects a specific signal waveform; and a control unit. The control unit: calculates, based on a time difference or a time ratio between multiple consecutive periods obtained from the specific signal waveform detected, a score indicating the stability of the periodic movement among the various periods; causes the biosignal analysis unit to extract a detected period from among the multiple consecutive periods on the basis of the calculated score and a threshold range for the time difference or time ratio; retrieves from the storage unit the image data generated for the extracted period from among the image data stored in the storage unit; and displays the retrieved image data on the display unit.
