Abstract:
A twin asymmetric scan slice thickness setting method for performing a scan with a first slice thickness in a first detector row of a multi detector and with a second slice thickness different than said first slice thickness in a second detector row, comprising the steps of:moving a position of a penetrating radiation beam and performing a scan while keeping the width of the penetrating radiation beam fixed at twice said first slice thickness to move the position of the penetrating radiation beam to a position at which count values for said first and second detector rows match, storing the count value for the detector row at this time, and then moving the position of the penetrating radiation beam and performing a scan while keeping the width of the penetrating radiation beam fixed at the sum of said first and second slice thicknesses to move the position of the penetrating radiation beam to a position at which the count value for said first detector row matches said stored count value.
