Abstract: A computer implemented method for modifying medical imaging protocol parameters can comprise receiving one or more modified protocol parameters for an imaging protocol and determining whether the one or more modified protocol parameters are acceptable based on at least one of: i) an acquired image acceptability check or ii) a parameter acceptability check.

Abstract: A device, system, method (100) and computer-program product are disclosed for respiratory monitoring of a subject's respiration during a magnetic resonance imaging session. The method comprises acquiring (101) magnetic resonance imaging data comprising k-space values along at least one trajectory segment in a k-space matrix, monitoring (102) the respiration of the subject by measuring one or more respiratory parameters, determining (103) a point in time when the center of the k-space matrix and/or the nearest point of the k-space trajectory segment to the center of the k-space matrix is sampled in acquiring (101) the magnetic resonance imaging data, and determining (104) the at least one respiratory parameter for said point in time using said monitoring (102) of the respiration.
