Abstract
A microscope is provided which includes an optical module, an OCT module, and a control device. The optical module is configured to generate optical image representations. The OCT module is configured to generate tomographic recordings. The control device is configured to determine the relative spatial position of a marking element, in each case from an optical image representation of the marking element and from a tomographic recording of the same marking element.
Claims17
A microscope, comprising:
- an optical module;
- an optical coherence tomography (OCT) module;
- and
- a control device in communication with the optical module and the OCT module,
- wherein the optical module is configured to generate optical image representations,
- wherein the OCT module is configured to generate tomographic recordings,
- wherein the control device is configured to determine a relative spatial position of a marking element from an optical image representation of the marking element and from a tomographic recording of the marking element, wherein the marking element has an outer shape which is configured such that the relative spatial position of the marking element is determinable from the tomographic recording of the outer shape of the marking element,
- wherein the marking element has at least one of a depression and an elevation, wherein
- a width of the at least one of the depression and the elevation decreases continuously from an end of a longitudinal extent of the marking element to an opposite end of the longitudinal extent of the marking element, and
- where in the marking element is provided on an outer surface of a medical instrument and movable relative to a treatment region.

A medical instrument, comprising:
- a marking element having at least one of a depression and an elevation,
- wherein the at least one of the depression and the elevation is embodied such that:
- (a) a relative spatial position of the marking element is determinable from an optical image representation of the at least one of the depression and the elevation generated by an
- optical module, and
- (b) the relative position of the marking element is also determinable from a tomographic
- recording of the at least one of the depression and the elevation generated by an OCT module,
- wherein the relative spatial position of the marking element defines a position and an
- orientation of the marking element,
- wherein the marking element has an outer shape which is configured such that the relative spatial position of the marking element is determinable from the tomographic recording of the outer shape of the marking element,
- wherein the marking element is provided on an outer surface of the medical instrument and movable relative to a treatment region during a calibration between the optical module and the OCT module, and
- wherein a width of the at least one of the depression and the elevation decreases continuously from an end of a longitudinal extent of the marking element to an opposite end of the longitudinal extent of the marking element.
