Hybrid navigation system for minimally invasive surgery-Phase

I: offline sensors calibration

M

inimally invasive surgery (MIS) is not currently widely used by surgeons due to

its cost and complex training requirement of surgeons. As a first step towards

making MIS a more accessible technology to use is to provide the surgeon with quality

images inside the patient as well as the surgical tool location automatically in real time

in a common reference frame. Then provide real time suggestions of how to navigate

inside the human body in order to follow the pre-operation (pre-op) path.The objective

of this paper is to build a platform to accomplish this goal. A set of three heterogeneous

asynchronous sensors is proposed to help the surgeon navigate surgical tools inside the

human body. The proposed system consists of a laser range scanner (LRS) to emulate

the CT/MRI whose image is used to generate the pre-op path by the surgeons, an

electromagnetic tracking system (EMTS) that provides three dimensional position and

orientation of the surgical tool inside the human body, and a small size camera attached

to the EMTS to provide real time images. This set of sensors provides all the necessary

information needed for MIS navigation. The sensors have different data rate, different

reference frames, and independent clocks. A prerequisite for successful navigation is to

represent all the sensors data in a common reference frame. The focus of this paper is

on off line calibration of the three sensors, i.e. before the surgical device is inserted in

the human body. This is a pre-requisite for real time navigation inside the human body.

The proposed off line calibration technique was tested using experimental laboratory

data. The accuracy of the calibration process was promising with an average error of

0.1081 mm and 0.0872 mm along the x and y directions, respectively, in the 2D camera

image.
