摘要: A tissue sensing device for use with an electrosurgical knife is proposed which comprises a proximal end portion, a distal end portion and a grip portion there between. The proximal end portion is configured for attachment to a housing of the electrosurgical knife. The distal end portion is configured for movably supporting a blade of the knife. A distal end of an optical fiber is arranged at the distal end portion of the device and a proximal end of the optical fiber is connectable to an optical console, so that optical measurements can be performed at the distal end portion.

摘要: The present invention relates to providing a projection data for providing a guidance image. In order to provide an enhanced guiding image technique for generating a guidance image of the patient's anatomy to be projected on the body surface of the patient, such that a at least a basis for a corrected guidance image for a better correlation to the patient's current motion can be provided, in particular to the patient's current breathing motion state, a device (10) for providing a projection data set is provided that comprises a storage means (12), an input interface (14), a processing unit (16) and an output interface (18). The storage means is configured to store a pre-determined basis data set representing a 3D tomographic image of a subject (20). The input interface is configured to receive reference data representing a current spatial depiction at least of a target region (22) of the subject. The processing unit is configured to register the reference data on the pre-determined basis data set. The processing unit is further configured to transform, based on the reference data and the result of the registration, the pre-determined basis data set resulting in a working data set representing a transformed 3D tomographic image indicating the current spatial anatomy relation at least for the target region of the subject. The processing unit is also configured to segment the working data set resulting in a projection data set representing the target region of the subject. Still further, output interface is configured to provide the projection data set for a further purpose.

摘要: A lens system comprises a first lens group and a second lens group, and is configured to form an image at a first magnification and at a second magnification. The lens system has a common optical axis in both magnifications. The lens system is further configured to form an intermediate image between the first lens group and the second lens group at the first magnification. The intermediate image formed in the first magnification is further imaged onto an optical detector. In the first magnification, the second lens group acts as a relay lens imaging the intermediate image onto the optical detector. In the second magnification, the first and second lens groups together form an image on the optical detector without forming an intermediate image.

摘要: Needle interventions are widely used in the field of oncology for taking biopsies of tissue in order to inspect whether tissue is cancerous or not. To make these interventions more reliable feedback of what kind of tissue is in front of the needle is required. A way to achieve this is by making use of optical spectroscopy. This requires integration of fibers into the needle. These fibers are used to deliver light to illuminate the tissue in front of the needle and to collect back the reflected light from the tissue. The present invention proposes to integrate the fiber distal ends in the slanted bevel of the needle in such a way that at least one source-detector fiber pair has a distance that is larger than the outer diameter of the needle.

摘要: An orthopedic pin is for optically analyzing a bone region. An optical fiber arrangement extends within an elongate shaft from a distal end to a proximal end. There is a coupling at an intermediate position along the shaft, and the optical fiber arrangement comprises a first portion on one side of the coupling and a second portion on the other side of the coupling. The coupling allows relative rotation between portions of the shaft at opposite sides of the coupling, while maintaining optical coupling between the first and second portions of the optical fiber.

摘要: An optical apparatus (200) includes an outer jacket (230), common cladding (220), and multiple single mode fiber cores (210). The common cladding (220) is within the outer jacket (230) and is used as multimode fiber such that the outer jacket (230) clads the common cladding (220). The single mode fiber cores (210) are within the common cladding (220) such that the common cladding (220) clads the plurality of single mode fiber cores (210).

摘要: The present invention relates to medical instrument tracking. In order to facilitate tracking a medical instrument, a system (100) is provided for tracking a medical instrument. The system comprises an instrument marker (14), a tracking arrangement (16), and a processing unit (18). The instrument marker is attached to the medical instrument on a marker position (20). The tracking system is configured to detect line segments (22) in the 5 field of interest and to detect the attached instrument marker. The processing unit is configured to identify a line segment (24) on which the attached instrument marker is detected as the medical instrument, and to determine an offset (26) between a position of a medical instrument tip (28) and the marker (14) by touching a reference marker (34) on the subject with the medical instrument (10).

摘要: The invention relates a system for implanting an implantable device in bone tissue, a processing unit for such system, a method of implanting an implantable device and a method of providing information for an implanting of an implantable device. In view of the finding that a fat content in cancellous bone is higher than a fat content in compact bone, the lipids fraction, which can be determined by optical means, e.g. spectroscopy, can be used to determine correct screw placement in healthy bone.

摘要: A mechanism for determining a shape of an interventional device. A mapping function is used to predict the position of an electrode, mounted on the interventional device, as the interventional device is moved within an anatomical cavity—to thereby form a sequence of predicted positions. The sequence of predicted positions is then processed to predict a shape of the interventional device.

摘要: A mechanism for generating a mapping function for mapping measurements taken at an electrode within crossing electric fields to a position or positions within a multidimensional co-ordinate system. The values for coefficients of the mapping function are generated using a first machine-learning algorithm, which receives, as input, example measurements (or responses) of the electrode and provides, as output, values for the coefficients for the mapping function. There is proposed a method and processing system for carrying out this mechanism.
