AngioTeacher is an interactive virtual simulator and self-learning medical software application to help cardiologists and students acquire advanced skills to interpret coronary angiograms. The model includes a whole human torso, and at its “heart” is a 3 dimensional computed tomographic angiographic model and associated coronary angiograms. Users can manipulate all anatomical structures of the human chest, viewing them in any angle, and making any one or a combination of them transparent to any level. This app is a must for those who want to deeply understand anatomical relationships of various vessels of the heart and its structures in a very flexible way. They can see them compared to “same case” coronary angiograms which are obviously less clear to start with but become clearer in this virtual simulator. The App is supported by other online specialist educational and assessment software.
