    Abstract: Disclosed is a computer-implemented method of transmitting identification information of a medical instrument. The method encompasses comparing a digital image of an instrument tray and an instrument to a digital image of just the instrument tray to determine the identity of the instrument. A characteristic geometry such as its envelope is assigned to the instrument, and a characteristic quantity of the envelope such as its aspect ratio may be used to identify the instrument. Based on determining, from the image of the instrument and the instrument tray, the relative position between those two entities, the method determines whether the instrument has been taken from the instrument tray, and accordingly instructs a medical computing system about this determination. The medical computing system may then determine whether the correct instrument has been taken from the instrument has been taken from the instrument tray, for example by comparison with medical procedure planning data.

    Abstract: Provided is a robotic microscope that includes an optical system being moveable in one or more spatial directions and an actuator configured to move the optical system in the spatial directions. The microscope includes a capacitive sensor with an electrode coupled to at least a part of the optical system, the capacitive sensor configured to provide a sensor signal indicative of a capacitance in a vicinity of the electrode. The microscope further includes control circuitry configured to determine, based on processing the sensor signal, at least one capacitance value for the capacitance, and configured to actuate, based on comparing at least one capacitance value with at least one reference value for the capacitance, the actuator to move the optical system such that a distance between a user's head and part of the optical system and/or an orientation of the user's head and part of the optical system is substantially constant.

    Abstract: Provided are a method and apparatus for determining displacement of an internal object disposed in a patient's body. The method includes positioning an arrangement of electrodes of a capacitive sensor adjacent to a patient's body part, such that each electrode is spaced apart from the body part, wherein the body part at least partly encloses the internal object of the patient. Providing, with the capacitive sensor, a plurality of sensor signals, wherein each sensor signal is indicative of a capacitance in a vicinity of at least one electrode of the arrangement of electrodes, determining a set of capacitance values for at least a subset of the electrodes of the arrangement of electrodes based on processing the plurality of sensor signals, and determining a displacement of the internal object with respect to the body part based on comparing the determined set of capacitance values with a set of reference capacitance values.
