The mathematical model of emission tomography problem at the disk is discussed. Uniqueness theorem and stability theorems for discrete data are proved. These results can be used for justification of different algorithms. Detailed and tested algorithm can be used for decision a problem when absorption coefficient depends only on radius of the disk.
