I am student of b.sc. in radiology tachnician can i teach ultrasonography?
Just after having done BSc Radiology, you aren't eligible to teach the courses in colleges. For that you need to acquire atleast a MSc and if possible a PhD in the subject, in order to be a teacher.
Now yeah! if you become a professor in any college, then obviously there will be interdisciplinary course profiles through which you will have to teach subjects like Ultrasonography.
