3D MEDICAL ANATOMICAL IMAGE SYSTEM USING 2D IMAGES
First Claim
1. A medical imaging system for generating 3D anatomical images from acquired 2D anatomical images, comprising:
- a synchronization processor for providing a synchronization signal identifying a particular phase of heart operation of a particular patient;
an image acquisition device for acquiring 2D anatomical images of a patient heart in angularly variable imaging planes over a plurality of different heart cycles at said particular phase of heart operation in response to said synchronization signal and in response to recorded data indicating imaging previously being performed at particular imaging plane angles to prevent imaging overlap at said particular imaging plane angles and to prevent unnecessary radiation exposure of said patient; and
an image processor for,storing the recorded data, andprocessing 2D images acquired by said image acquisition device of said patient heart in a plurality of different imaging planes having relative angular separation, to provide a 3D image reconstruction of said patient heart.

Abstract
A medical imaging system generates 3D anatomical images from acquired 2D anatomical images. The system includes a synchronization processor for providing a synchronization signal identifying a particular phase of heart operation of a particular patient. An image acquisition device acquires 2D anatomical images of a patient heart in angularly variable imaging planes over multiple different heart cycles at the particular phase of heart operation in response to the synchronization signal and in response to recorded data indicating imaging previously being performed at particular imaging plane angles. An image processor stores the recorded data to prevent imaging overlap at the particular imaging plane angles and to prevent unnecessary radiation exposure of the patient. The image processor processes 2D images acquired by the image acquisition device of the patient heart in multiple different imaging planes having relative angular separation, to provide a 3D image reconstruction of the patient heart

17. A method of X-ray medical imaging for generating 3D anatomical images from acquired 2D anatomical images, comprising the activities of:
-
generating a synchronization signal identifying a particular phase of heart operation of a particular patient; acquiring 2D anatomical images of a patient anatomical portion in angularly variable imaging planes over a plurality of different heart cycles at said particular phase of heart operation in response to an imaging trigger signal; recording data during acquisition of images identifying whether an image has been acquired at particular imaging plane angles; generating said imaging trigger signal from said synchronization signal and the recorded data, said imaging trigger signal being for initiating and inhibiting image acquisition at particular imaging plane angles by said image acquisition device and preventing imaging overlap at said particular imaging plane angles and unnecessary X-ray radiation exposure of said patient; and processing 2D images acquired by said image acquisition device of said patient anatomical portion in a plurality of different imaging planes having relative angular separation, to provide a 3D image reconstruction of said patient anatomical portion. - View Dependent Claims (18)
