Abstract: A method for registration of virtual endoscopy images in first and second patient positions comprises performing colon segmentation and feature extraction, including centerline and colon surface data for each of the images; resampling the centerline and colon surface data; computing respective local descriptors; pairing point correspondences on the centerlines between the first and second images by minimal cost matching; extrapolating the centerline point correspondences to a 3-dimensional/3-dimensional (3D/3D) transformation between the first and second images. The method also includes selecting a position for a virtual endoscope in one of the images; associating an orthogonal reference frame with the virtual endoscope; and applying the 3D/3D transformation to the orthogonal reference frame so as to derive a corresponding transformed reference frame for the virtual endoscope in the other of the images.

Abstract: Apparatus for determining a proper insertion depth of a biopsy needle so that a sampling end of the needle just reaches to a designated target area within the body comprises at least one straight calibrated pointing device aligned to point through the selected point in a straight line passing through the designated target region. The pointing device exhibits first and second markers along its length such that respective images are formed on a first image plane by utilizing radiation from a radiation source, along with images corresponding to the selected point and the target area. The images are formed along a straight line in this order: (A) the first marker, (B) the second marker, (C) the selected point, and (D) the target region. The apparatus includes an arrangement for measuring distances on the image plane between images (A), (B), (C), and (D) and a calculator for calculating the cross ratio of the distances, whereby the proper insertion depth of the biopsy needle is determined.

Abstract: Systems and methods are provided to record at least a first and a second image of a marking on a surface of an object with a mobile computing device including a processor, a display and a camera with a lens. The lens and the display are located at the same side of the body of the computing device. The first image is taken with a first part of the display illuminating the object and the second image is taken with a second part of the display illuminating the object illuminating the object from different directions. Different illumination directions provide different shadow effects related to ridges and grooves on the surface. Processing the images which are substantially registered allows extraction of markings created by ridges and or grooves on the surface of the object. Computer tablets and smart phones perform the steps of the present invention.

Abstract: With a method for controlling the dose or dose rate when recording x-ray images by means of a detector comprising image elements which record a plurality of dose data values, an actual value is determined for the dose or dose rate from the totality of the data values recorded by the image elements of a predetermined image segment, said actual value being compared with a predetermined target value in order to control the dose or dose rate when recording a further x-ray image. In accordance with the invention, the actual value is determined such that on the basis of a frequency distribution of the dose data values of the image elements assigned to the dominant, a p-quantile is determined, and that the dose data value assigned to the p-quantile is used to determine the actual value.

Abstract: A computer-controlled method for automatically positioning a guide for a biopsy needle for its proper insertion into the body of a patient from a selected point on a surface of the body, so as to enter in a straight line passing through a designated target region within the body, in conjunction with an imaging system utilizing radiation from first and second source positions for deriving first and second radiographic images. The method includes the steps of (a) selecting a first auxiliary plane at an angle &THgr;1; moving the guide within the first auxiliary plane to an angle &phgr;1 so as to cause the guide image on the first image plane to be aligned in a straight line through the target region; (b) storing values for the angles &THgr;1 and &phgr;1; selecting a second, different, auxiliary plane at an angle &THgr;2; (c) moving the guide to an angle &phgr;2 within the second auxiliary plane so as to cause the guide image on the second image plane to be aligned in a straight line through the target region; storing values for the angles &THgr;2 and &phgr;2; calculating, by utilizing values stored for the angles, rotations &agr; and &THgr; so as to derive a first viewing plane &pgr;; and (d) moving the guide within the first viewing plane &pgr; to an angle &phgr;3 so as to cause the guide image on the second image plane to be aligned in a straight line through the target region, whereby the guide is properly aligned.
