Is Visual Registration Equivalent to Semiautomated Registration in Prostate Biopsy?

Figure 2

Spatial distances between visually identified targets and software registration defined targets. (a) Relative variability and variation of visual registration by two operators in 16 lesions. (b) Spatial distances by the two operators were plotted. The distances were sorted by the distance of OP1. More experienced operator (OP1) shows better reproducibility.
