Image processing unit for medical X-ray apparatus comparing actual image of body volume with preceding image for adjacent movement phase of imaged body volume

摘要

The image processing unit (5) has an input for the image signal (8) from the X-ray apparatus and an input for a signal (9) indicating the movement phase of the imaged body volume of the patient (2), a memory storing previous images for the body and the corresponding movement phases, with determination and display of the spacing between the movement phases for the actual image and the immediately preceding image of the body volume. An Independent claim for a method for correlation of an actual image of a body volume with a preceding image for a different movement phase is also included.
