Three-dimensional recording system of the path of the surgical instrument type Jarit; Metric dispersion

The aim of the present work is to present the partial results of a three-dimensional recording system of the Jarit surgical instruments. The 3D record was made by processing images in Matlab and passive markers in the instruments. Coordinates home and end of the path was determinate. And through two web cam the registration of the instrument path was made. The records of the neurosurgeons are shown and the concept of the metric dispersion is introduced. As a partial result we can conclude that it was possible to measure the metric dispersion. The record was made in different planes (X-Z) superior view, (X-Y) lateral plane and (Z-Y) Frontal view. Also, the main characteristics of the proposal were determined.
