Abstract

In this study, the role of different 3D vision systems on the patient safety in the context of robotic surgery was studied. Clearly safety is the foremost importance in all surgical procedures. It is well studied in the clinical surgical procedures but the role of different 3D vision system in the context of patient safety is hardly ever mentioned. The assessment of the quality of the 3D images and role of force feedback was studied with two distinct methods (spatial estimation and depth perception) in two different vision systems (holographic and stereovision). The main idea in this study is to investigate quantitatively the role of the vision system in patient safety.

Robot-assisted surgery

Robot-assisted surgery or robotic surgery are any types of surgical procedures that are performed using robotic systems. Robotically assisted surgery was developed to try to overcome the limitations of pre-existing minimally-invasive surgical procedures and to enhance the capabilities of surgeons performing open surgery. In the case of robotically assisted minimally-invasive surgery, instead of the surgeon directly moving the instruments, the surgeon uses one of two methods to perform dissection, hemostasis and resection, using a direct telemanipulator, or through computer control.

Stereopsis

Stereopsis () is the component of depth perception retrieved through binocular vision. Stereopsis is not the only contributor to depth perception, but it is a major one. Binocular vision happens because each eye receives a different image because they are in slightly different positions on one's head (left and right eyes). These positional differences are referred to as "horizontal disparities" or, more generally, "binocular disparities". Disparities are processed in the visual cortex of the brain to yield depth perception.

Computer vision

Computer vision tasks include methods for , , and understanding digital images, and extraction of high-dimensional data from the real world in order to produce numerical or symbolic information, e.g. in the forms of decisions. Understanding in this context means the transformation of visual images (the input to the retina in the human analog) into descriptions of the world that make sense to thought processes and can elicit appropriate action.
