The lab portion will be pre-recorded video & student lab assignments monitored remotely by the instructor. You will need to have access to your x-ray equipment for a minimum of 4 hours on the 4th day of class. We understand it can be a challenge to get access to x-ray equipment during class time. In this case, the lab exercises can be done as homework to review in class during lab time.
