Preparation of a scan protocol of a medical imaging apparatus is provided. A first parameter set that includes one or more first scan parameters is provided. One or more first scan parameter values that are assigned to the one or more first scan parameters are set. Based on these set one or more first scan parameter values, a second parameter set that includes one or more second scan parameters is determined. The second parameter set is provided, and one or more second scan parameter values that are assigned to the one or more second scan parameters are set. Based on the one or more first scan parameter values and/or the one or more second scan parameter values, a scan protocol is prepared. Based on the scan protocol prepared, scan data is acquired by the medical imaging apparatus.
