Abstract

Strict sterility requirements impose restrictions on the type of equipment and its handling in an operating room (OR). This paper proposes three methods for intraoperative calibration of a tracked ultra- sound probe under sterile conditions. We categorically call these methods air calibration to contrast them with the common phantom-based cal- ibration methods that employ a coupling medium (e.g. a water-bath). The methods each consist of a preoperative and an intraoperative cali- bration stage. The preoperative stage is performed once in a non-sterile environment where any of the existing calibration methods can be used. The intraoperative stage is performed before each intervention in the OR. To minimize impact on the interventional work-flow, we required that the intraoperative calibration took less than 10 minutes, produced a robust result and was easy to perform.
