MULTIPLANAR REFORMATTING VISUALIZATION WITH MULTIPLE SCROLLING SPEEDS

摘要

Multiplanar reformatting visualization is provided with multiple scrolling speeds. A plurality of buffers is provided. Each buffer stores composites of data from different planes. The amount of compositing to generate a total composite for a visualization may be less since the division into partial composites may reduce addition and subtraction or other compositing operations. One level of partial composite buffers may be used. The total is recomputed for each visualization. In other embodiments, a hierarchal buffer structure is used. For example, a total composite buffer is provided in addition to the partial composite buffers. By re-compositing the partial composites before and after adjustment for scrolling increment from the total composite buffer, the total composite is updated for scrolling. Two or more levels of buffers may be used.
