1. An imaging system that allows for modification of data acquisition parameters, where the parameters affect dose distribution, comprising:
- a library of exams, wherein the library of exams comprises a plurality of scans from different patients; and
a computer programmed to;
obtain a set of scanning parameters for image data acquisition and image reconstruction;
select a scan from among the plurality of scans from the library of exams based on a similarity metric for a patient to be scanned and obtain scan data from the scan;
simulate a new scan of the patient using the obtained scan data and using the obtained set of scanning parameters; and
generate a new set of scanning parameters based on the simulation.

Abstract
An imaging system allows for modification of data acquisition parameters, where the parameters affect dose distribution. The system includes a library of exams, and a computer programmed to obtain a set of scanning parameters for image data acquisition and image reconstruction, obtain scan data from the library of exams that is based on a similarity metric for a patient to be scanned, simulate a new scan of the patient using the obtained scan data and using the obtained set of scanning parameters, and generate a new set of scanning parameters based on the simulation.

11. A method of optimizing scanning parameters for image data acquisition, comprising:
-
selecting a scanning protocol for image data acquisition and image reconstruction; select a scan from among a plurality of scans from a library of exams based on a similarity metric for a patient to be scanned and obtain scan data from the scan, wherein the library of exams comprises the plurality of scans from different patients; determining whether the scanning protocol achieves a desired optimization by simulating a new scan of the patient that is based on the selected scanning protocol and based on the obtained scan data; and generating a new scanning protocol based on the optimization. - View Dependent Claims (12, 13, 14, 15, 16)
