LROC Results Indicating Impact of Lesion Location on Detection for Frame av. The areas under the LROC curve indicate that detection of tumors in the apex where little motion occurs is difficult. The influence of anatomic location of lesions on detection is evident for each reconstruction strategy. For all tumor locations, RBI with AC_RC_SC provides the best results.
