Dynamic circular buffering: a technique for equilibrium gated blood pool imaging

摘要

We have devised a software technique called “dynamic circular buffering” (DCB) with which we create a gated blood pool image sequence of the heart in real time using the best features of LIST and FRAME mode methods of acquisition/processing. The routine is based on the concept of independent “agents” acting on the timing and position data continuously written into the DCB. This approach allows efficient asynchronous operation on PC-type machines and enhanced capability on systems capable of true multiprocessing and multithreading.
