Document Type and Number:
Japanese Patent JP5405056
Kind Code:
B2
Abstract:
Method of operating an X-ray CT apparatus and the corresponding apparatus and system thereof. A method includes analyzing scout scan data to obtain a position with a minimum noise index and a position with a maximum noise index, calculating noise indexes at the two positions in a range of a maximum and a minimum tube current that can be provided by the system by means of a tube current control model so as to obtain two ranges of noise index, and determining whether there is an intersection between the two ranges of noise index. If such an intersection exists, a combination of the range of tube current value and the range of noise index that meets the requirement is selected within the intersection to control the system to proceed with a subsequent scan. If no such intersection exists, the system ends the present scan.
