32results about How to "Resolution is deteriorated" patented technology

An imaging apparatus has image sensors, an imaging optical system of which relative position with the image sensors is fixed, and a merging unit which connects images obtained by imaging while changing the relative position between the image sensors and the imaging optical system. Aberration of the imaging optical system in an image obtained by each image sensor is predetermined based on the relative position between the imaging optical system and the image sensor. The merging unit smoothes seams of the two images by setting a correction area in an overlapped area where the two images to be connected overlap with each other, and performing correction processing on pixels in the correction area. A size of the correction area is determined according to the difference in aberrations of the two images, which is determined by a combination of image sensors which have imaged the two images.

Image quality deterioration due to a drop in resolution or lowering of S / N ratio while reducing the amount of data stored during a 3D data acquisition process, and shortening the time from the start of an examination to the end of imaging. The method and apparatus of this invention perform, in parallel with the 3D data acquisition process, addition of sinograms, reading of subsets of the sinograms having been added, and image reconstruction. Consequently, the amount of data stored is reduced, and the time from the start of an examination to the end of imaging is shortened. At the same time, since 3D iterative reconstruction is not accompanied by conversion from 3D data to 2D data, a drop in resolution due to errors occurring with the conversion from 3D data to 2D data is avoided. The 3D iterative reconstruction can directly incorporate processes such as an attenuation correction process. It is thus possible to avoid also a lowering of S / N ratio resulting from an indirect incorporation of such processes.
