We conducted a study of participants' abilities to place a laparoscopic port for in vivo biosensor use. Biosensors have physical limitations that make port placement crucial to proper data collection. A new port placement algorithm enabled evaluation of port locations, using segmented patient data in a virtual environment. Methods Port placement scoring algorithms were integrated into an imageguided surgery system. Virtual test scenes were created to evaluate various scenarios encountered

Participants' scores were also compared to those of a port placement algorithm. Results The port placement algorithm consistently outscored participants by 10-25%. Participants were inconsistent from trial to trial and from participant to participant.
