发明名称 SYSTEM AND METHOD FOR AUTOMATIC START TIME ADJUSTMENT IN MULTI-PHASE SCANNING
摘要 An MR apparatus creating a timeline suitable for data acquisition in several temporal phases. The MR apparatus including a method for creating a timeline TL2 having a scan time of TS1 based on a reference timeline TL0 having a scan time of TS. The method setting start points in time of scans SC1, SC3 and SC4 in the timeline TL2 to the same points in time as those in the reference timeline TL0, respectively. The method also setting the start point in time of the scan SC2 in the timeline TL2 to a sum of the scan time TS1 and a delay time TD1 with respect to the scan SC1 in the timeline TL2.

主权项 1. A setting apparatus provided in a medical apparatus conducting a first scan for acquiring data in a first temporal phase from a subject to whom a contrast medium is administered, a second scan for acquiring data in a second temporal phase from said subject, and a third scan for acquiring data in a third temporal phase from said subject, said setting apparatus being for setting conditions in conducting said first, second, and third scans, said setting apparatus comprising: a processor for creating a second timeline based on a first timeline, said first timeline defining a start point in time of said first scan having a first scan time, a start point in time of said second scan, a start point in time of each third scan, and a first delay time from the end of said first scan to the start of said second scan, said second timeline being a timeline in which the scan time of said first scan is modified from said first scan time to a second scan time, wherein said processor sets: a start point in time of said first scan in said second timeline to the same point in time as that in said first timeline; a start point in time of said second scan in said second timeline to a point in time delayed relative to the start point in time of said first scan in said second timeline by a sum of said second scan time and said first delay time; and a start point in time of said third scan in said second timeline to the same point in time as that in said first timeline.
