Abstract: 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.

Abstract: A contact-free method of determining biometric parameters and physiological parameters of a subject of interest (20) to be examined by a medical imaging modality (10), comprising steps of taking (72) a picture by a first digital camera (52) including a total view of an examination table (44); applying (74) a computer vision algorithm or an image processing algorithm to the picture for determining a biometric parameter of the subject of interest (20) in relation to the examination table (44); taking (78) at least one picture with a second digital camera (58), whose field of view (60) includes a region of the subject of interest (20) that is related to the at least one determined biometric parameter; using data indicative of the determined biometric parameter to identify (82) a subset of pixels of the at least one picture taken by the second digital camera (58) that define a region of interest (64) from which at least one physiological parameter of the subject of interest (20) is to be determined, taking (84) a

Abstract: 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).

Abstract: 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.
