Research Abstract

The final goal of this project is to detect cardiovascular abnormality in its early stage. For this purpose synchrotron radiation (SR) imaging is quite useful to find precise structure on moving organs, and it gives us spectral information of objects. On the other hand, we can get more exact structures and functions of living organs from time sequence images. Here we developed a system and several algorithms to realize such analysis.
Two spectrum images obtained in 2ms, i.e. ignorable time interval for cardiac motion, image data sequences are recorded in IC memory bank with required reference time series signal. Each image data is 512x512 size with 12bit depth, and the usual time difference between two spectrum image sequences is 2ms. For fast correction of image distortion and real time DSA, a fast data processing board is prepared and more sophisticated processing are executed on a work station connected to this recording system.
Several basic algorithms for the analysis of image sequence and information extraction for evaluation of organs are developed on related practical problems, e.g. 3D coronary structure identification from biplane image time sequences, detection and tracking moving targets and imaging of specific materials in organs from spectrum images.
A few problems on the optical system for SR imaging is also studied. For the suppression of scattering X-ray flux and the fast switching of X-ray spectrum for energy subtraction imaging, we found solutions, and their implementation are continuing. Improvement of diagnosing algorithm and clinical evaluation of this system is the next problem.
