摘要： An image guided surgery system comprises an endoscope (11) with an image pick-up apparatus and a position measuring system (10, 21) for measuring the position of the endoscope (11). A data processor (2) is arranged to process image data according to the measured position of the endoscope and derive combined image data from the processed image data and image information from the image pick-up apparatus. The processed image data are derived from said image data and said image information from the image pick-up apparatus and said measured position. For example the image data are CT or MRI images or the image data represent one or several anatomical landmarks in the body of a patient (12) to be examined.

摘要： An x-ray bone densitometry apparatus having a patient table with a length extending along a Y-axis and a width extending along an X-axis and a C-arm supporting an x-ray source at one side and an x-ray detector at an opposite side of the table such that the source and detector are aligned along a source-detector axis which is transverse to the Y-axis. The source is selectively energised to emit a beam of x-rays which conforms to a beam plane which is transverse to the Y-axis and contains the source-detector axis. Either, or both, the C-arm and the table are selectively movable relative to the other to scan a selected region of a patient on the table along the Y-axis with the beam of x-rays at different angles without moving the patient. The detector measures x-rays from the beam of x-rays in each of the beam planes along the selected region of the patient at at least two different angles as x-ray measurements, each x-ray measurement including certain bone information but less than all corresponding soft tissue information between sides of the patient in the beam plane.
A processor processes the x-ray measurements from the detector corresponding to the scan of the selected region to substantially cancel out the soft tissue information while retaining the bone information from the x-ray measurements to generate a three-dimensional image reconstructing bone structure without soft tissue for the selected region.

摘要： An embodiment of the targeting system includes a penetrating beam emitter (10), a penetrating beam receiver (13), and a targeting assembly (16). The targeting assembly is adjustable. The targeting assembly (16) has a targeting marker in a path of a penetrating beam (19) provided by the emitter (10). The targeting marker is at least partially opaque to a penetrating beam (19) emitted by the emitter (10), and the targeting marker indicates a targeting point on a target axis. The targeting assembly (16) further includes a targeting beam device capable of providing a targeting beam along the target axis. In addition, the present invention includes a method of calibrating a targeting system, and a method of targeting an area of interest.

摘要： In an X-ray imaging system having a detector and a tube disposed to project an X-ray beam field into the plane of the detector, visual indicators associated with the detector and the X-ray beam field, respectively, are provided for use in aligning the detector and beam field. A computational device is also provided for producing a signal representing offset, caused by X-ray beam angulation, between the geometric center of the beam field and the point at which the central axis of the projected X-ray beam intersects the detector plane. A displays device, responsive to the produced signal, enables a system user to compensate for the offset when aligning the detector and beam field.

摘要： The invention relates to a device for detecting the position and orientation of a body (36) within at least one three-dimensional system of co-ordinates (5; 24). The inventive device comprises A) a position detecting sensor (1) and B) a computer (8) that is connected to the position detecting sensor (1) for detecting the position and orientation of a body (36) within at least one system of co-ordinates (5; 24; 26), whereby C) the device comprises auxiliary means (25) for detecting the direction of the gravity vector (19). The invention also relates to a method for correcting the defects in magneto-optical X-ray photographs (35). Said defects occur caused by influences related to gravity and the terrestrial magnetic field. Said method comprises the steps: a) detecting the direction of the gravity vector (19), b) detecting the position and orientation of the X-ray apparatus (28), c) detecting the distortions of the X-ray photograph (35), whereby said distortions are produced by gravity-related, mechanical deformations of the X-ray apparatus (28), d) detecting the defects in the X-ray photograph (35), whereby said defects are caused by the local terrestrial magnetic field, e) detecting the optical deformations of the X-ray photograph (35), whereby said deformations occur in the receiver (29) and f) correcting the digitised X-ray photograph by means of a computer (8) in relation to the defects detected in the steps d), e) and f).
