Figure 2

Example of RTI adjusted CCMR compared against a non-RTI approach reference. Top: RTI and non-RTI NAV profiles. RTI: 324 HBs; NavEff = 62% vs non-RTI: 438 HBs and 46%. Operator interaction involved expanding the navigator gating window size from 5 mm to 7.5 mm midway (136th out of 324 HBs) during the scan. This increased the navigator efficiency from 56% (first 136 HBs) to 66% (Remainig 188 HBs). Bottom: Acquired RCAs. Sharpness scores were (RTI: 0.52) vs (non-RTI: 0.48).
