Multimodality workstation for cardiac image sequences

The methods currently used at the University of Ottawa Heart Institute for storing, viewing and manipulating echocardiographic and cardiac angiographic examinations, are aimed at helping specialists in performing their diagnoses. It is cumbersome for attending cardiologists to review these studies and in particular, it is next to impossible for them to simultaneously view and compare studies, even between different views from the same study. This paper details our efforts in designing, constructing and evaluating a computer-based workstation to give the attending physician easy access to the recently acquired studies, and to allow them to do comparisons between studies, even of different modalities.
