Organ movement e.g. heartbeat, representation method for human body, involves reconstructing three-dimensional image data from projection images i.e. tomosynthesis projection images

摘要

#CMT# #/CMT# The method involves recording projection images from different camera angles between starting position and ending position by an image recording unit (4) during recording. Three-dimensional image data are reconstructed from the projection images i.e. tomosynthesis projection images. Tomosynthesis projection images are recorded along a tomosynthesis scanning path (14) for producing the projection images from different camera angles, where the tomosynthesis scanning path is formed in circular, elliptic, loop or spiral shape. #CMT#USE : #/CMT# Method for three-dimensional representing of organ movement e.g. heartbeat, breathing, intestine movement or mechanical compression of a tissue from outside of a human body by a tomograpic or tomosynthesis process for imaging the human body. #CMT#ADVANTAGE : #/CMT# The method allows functional imaging to be easily realizable with a C-arm-angiography-system in interventional surroundings. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a three-dimensional scanning geometry for circular tomosynthesis of a closed scanning path. 4 : Image recording unit 14 : Tomosynthesis scanning path 15 : Coordinate system 16 : Cone 17 : Circuit path.
