A tangible interface for augmented reality visualisation in 4d echocardíography...
Dias, J. M. S.; Aurélio, M.; Carvalho, H.; Rosário, L.; Carvalho, L. S.; Rocha, I.ln this work, we report a Tangible Augmented Reality system that can be applied to interactive visualization scenarios in the cardiology medical field, such as in the teaching of medical techniques or the recognition of organs. Moreover, it can be used for more detailed and natural interaction with virtual models of organs or other physiological structures of the human body. The system allows users to naturally...
Calcium identification and scoring based on echocardiography. An exploratory st...
Elvas, L. B.; Almeida, A. G.; Rosário, L.; Dias, J.; Ferreira, J.Currently, an echocardiography expert is needed to identify calcium in the aortic valve, and a cardiac CT-Scan image is needed for calcium quantification. When performing a CT-scan, the patient is subject to radiation, and therefore the number of CT-scans that can be performed should be limited, restricting the patient’s monitoring. Computer Vision (CV) has opened new opportunities for improved efficiency when ...
