Hello,
I hope someone can help me with my problem. I was reading something about how a CT-scan works, and how an image is made.
After the scanning is done, the result is the amount of radiation that passed all the internal tissue (when he object is for example a human body) in it's path, and this is done 360 degrees around the object.
Now, through tomography a 2D image is made. The way I see it (I don't know if this is right), the image is made by filling in the pixels where the intersection of the object is made of. The colour of the pixel gives the amount of radiation that is absorbed.
Now here is my problem. How do you know that the final image that is created by the algorithm is unique? Aren't there more possibilities if you only know the total radioation that is absorbed? or are there just so many pixels that there can only be one solution?
I hope someone can help me, or explain to me on what part I'm wrong (or do I think to easily?)
thanks!![]()
