About the projection data of the CT dataset from 2016 NIH-AAPM-Mayo Clinic Low Dose CT Grand Challenge

Hello! I wonder why the size of the projection data is 64x736? Some of the literature I found said that the size of the projection data should be 2304x736. Why does the projection data look so narrow, not like the general projected data that I've seen before.

The general projected data that I've seen before in a literature.

The second image you have added is called a sinogram which is formed by stacking projection data. In projection data of the CT dataset from 2016 NIH-AAPM-Mayo Clinic Low Dose CT Grand Challenge, the size of one projection data is 64x736. To get a sinogram (which is 2304x736 ), appx. 36 projection data has to be stacked.
