Dedicated display for processing and analyzing multi-modality cardiac data
First Claim
1. A computer-implemented method comprising the steps of:
- (a) obtaining cardiac image measurements of a patient from different imaging modalities to obtain volume image data of cardiac functional features from one imaging modality and volume image data of cardiac structural features from another imaging; and
(b) displaying, to a human user, a fused volume rendered view of the volume image data of the cardiac functional features and the volume image data of the cardiac structural features.

Abstract
For diagnosis and treatment of cardiac disease, images of the heart muscle and coronary vessels are captured using different medical imaging modalities; e.g., single photon emission computed tomography (SPECT), positron emission tomography (PET), electron-beam X-ray computed tomography (CT), magnetic resonance imaging (MRI), or ultrasound (US). For visualizing the multi-modal image data, the data is presented using a technique of volume rendering, which allows users to visually analyze both functional and anatomical cardiac data simultaneously. The display is also capable of showing additional information related to the heart muscle, such as coronary vessels. Users can interactively control the viewing angle based on the spatial distribution of the quantified cardiac phenomena or atherosclerotic lesions.
