摘要： There is provided a method for at least partly determining the orientation of an edge-on x-ray detector with respect to the direction of x-rays from an x-ray source. The method includes obtaining (S1) information from measurements, performed by the x-ray detector, representing the intensity of the x-rays at a minimum of two different relative positions of a phantom in relation to the x-ray detector and the x-ray source, the phantom being situated between the x-ray source and the x-ray detector and designed to embed directional information in the x-ray field when exposed to x-rays. The method also includes determining (S2) at least one parameter associated with the orientation of the x-ray detector with respect to the direction of x-rays based on the obtained information from measurements and a geometrical model of the spatial configuration of the x-ray detector, x-ray source and phantom.

摘要： [Objective]
Shifts due to movement of subjects are enabled to be detected in addition to shifts at the boundaries of images due to mechanical errors when combining a plurality of radiation images obtained by lengthwise imaging.
[Constitution]
A mechanical error correcting section (34) corrects image distortion within images obtained by imaging due to mechanical errors in an imaging surface. A shift detecting section (35) detects amounts of shift based on body movement of a subject N within mechanical error corrected images, in which image distortion due to mechanical errors in an imaging surface have been corrected. A body movement obtaining section (36) detects the amounts of body movement during imaging based on the amounts of shift, and a body movement correcting section (37) corrects for the amounts of shift of the subject within the mechanical error corrected images, based on the amounts of body movement.

摘要： The invention relates to a method and to a device for visually assisting a catheter application on the heart (H) of a patient (P) using at least one image of the patient (P) obtained by means of a C-arm X-ray device (1) and using electroanatomic mapping-data of the patient (P) that is obtained by means of an electromagnetic position detection system and mapping system (2). The C-arm X-ray device (1) and the electromagnetic position detection system and mapping system (2) are calibrated in relation to each other, by means of the determination of a co-ordinate transformation between a co-ordinate system (CR) assigned to the C-arm x-ray device (1) and/or a co-ordinate system (CB) that is assigned to the at least one image generated by the C-arm X-ray device (1) and a co-ordinate system (CM) assigned to the electromagnetic position detection system and mapping system (2). The position of the patient (P) is determined during the detection of the image and/or during the detection of the electroanatomic mapping-data and is at least indirectly assigned to the image and/or the electroanatomic mapping-data.
