Welcome back everybody to Medical Engineering. Today I want to take the opportunity to start looking into the technique of Computed tomography. So the idea here is that we can use X-rays to create shadow images of the patient and we’ve already seen that this essentially are sums along the ray. Now we want to reconstruct the virtual slice images like virtually chopping the patient into slices and then look inside the patient such that we can improve diagnosis. So looking forward to exploring computed tomography with you guys.
