1. A method for implementing a magnetic resonance (MR) examination, comprising:
prior to operating an MR scanner, comprising an imaging volume and a patient bed, to acquire MR data from a subject, according to a predetermined MR data acquisition protocol, as the patient bed, with a patient thereon, is moved through a succession of bed positions that respectively cause different anatomy of the patient to be successively situated in said imaging volume, determining, in a computer, the respective anatomy of the patient that is present in the imaging volume for each of the bed positions; in said computer, determining a specific absorption rate for each of said bed positions dependent on the respective anatomy of the patient that is present in the imaging volume at the respective bed position and the predetermined magnetic resonance protocol, said specific absorption rate defining an absorption of electromagnetic energy in biological tissue of the patient, resulting from the predetermined MR data acquisition protocol at the respective bed position; in said computer, comparing the determined specific absorption rates for each bed position with an absorption rate threshold value; and at a graphical interface in communication with said computer, emitting a notification when at least one of said specific absorption rates exceeds said absorption rate threshold value. |
