Planning an external ventricle drainage placement

A medical tracking method for tracking a spatial position of a medical instrument within a medical workspace including an anatomical structure of a patient. The method includes: acquiring, using a first camera targeted on the medical workspace, instrument position data describing a spatial position of the medical instrument with respect to a first camera; acquiring, using a second camera and at least one optical tracking marker that is adapted to be recognized by the second camera, camera position data describing a spatial position of the first camera with respect to the anatomical structure, determining, based on the instrument position data and the camera position data, tracking data describing the spatial position of the medical instrument with respect to the anatomical structure; and tracking the spatial position of the medical instrument within the medical workspace using the tracking data.

Optical tracking

A data processing method performed by a computer for supporting a medical brain mapping procedure, comprising the steps of receiving a microscope image of a patient's cortex and superimposing stimulation response marks onto the microscope image, wherein a stimulation response mark indicates the patient's response to an electrical stimulation of the cortex by a stimulation probe at a position associated with the stimulation response mark.
