A hybrid imaging system comprising: a magnetic resonance scanner disposed in a radio frequency isolation space surrounded and defined by a radio frequency shield; a second modality imaging system disposed in the same radio frequency isolation space as the magnetic resonance scanner, the second modality imaging system including radiation detectors (68, 70, 70') configured to detect at least one of high energy particles and high energy photons and being one of a positron emission tomography scanner, a gamma camera for performing SPECT imaging or a computer tomography scanner, wherein the magnetic resonance scanner and the second modality imaging system are physically separate units that are spaced apart by a gap; a patient bed disposed in the gap between the magnetic resonance scanner and the second modality imaging system and configured to load a patient disposed on the patient bed into either the magnetic resonance scanner or the second modality imaging system; and second modality electronics (80, 82) associated with said radiation detectors (68, 70, 70'), said second modality electronics (80, 82) comprising a component being clocked at a high frequency such as dynamic memory or synchronous digital electronics, said second modality electronics (80, 82) being configured to substantially reduce radio frequency interference generated by the second modality electronics at one or more magnetic resonance frequencies of the magnetic resonance scanner by - clocking said component at a frequency selected to suppress generation of radio frequency interference at the one or more magnetic resonance frequencies of the magnetic resonance scanner, or by - selectively placing said second modality electronics (80, 82) into quiet mode with clocks for synchronous digital electronics and dynamic memory disabled and power supplies for radiation detectors turned off, or by providing - a notch filter tuned to block generation of radio frequency interference at the one or more magnetic resonance frequencies of the magnetic resonance scanner. a magnetic resonance scanner disposed in a radio frequency isolation space surrounded and defined by a radio frequency shield; a second modality imaging system disposed in the same radio frequency isolation space as the magnetic resonance scanner, the second modality imaging system including radiation detectors (68, 70, 70') configured to detect at least one of high energy particles and high energy photons and being one of a positron emission tomography scanner, a gamma camera for performing SPECT imaging or a computer tomography scanner, wherein the magnetic resonance scanner and the second modality imaging system are physically separate units that are spaced apart by a gap; a patient bed disposed in the gap between the magnetic resonance scanner and the second modality imaging system and configured to load a patient disposed on the patient bed into either the magnetic resonance scanner or the second modality imaging system; and second modality electronics (80, 82) associated with said radiation detectors (68, 70, 70'), said second modality electronics (80, 82) comprising a component being clocked at a high frequency such as dynamic memory or synchronous digital electronics, said second modality electronics (80, 82) being configured to substantially reduce radio frequency interference generated by the second modality electronics at one or more magnetic resonance frequencies of the magnetic resonance scanner by - clocking said component at a frequency selected to suppress generation of radio frequency interference at the one or more magnetic resonance frequencies of the magnetic resonance scanner, or by - selectively placing said second modality electronics (80, 82) into quiet mode with clocks for synchronous digital electronics and dynamic memory disabled and power supplies for radiation detectors turned off, or by providing - a notch filter tuned to block generation of radio frequency interference at the one or more magnetic resonance frequencies of the magnetic resonance scanner. - clocking said component at a frequency selected to suppress generation of radio frequency interference at the one or more magnetic resonance frequencies of the magnetic resonance scanner, or by - selectively placing said second modality electronics (80, 82) into quiet mode with clocks for synchronous digital electronics and dynamic memory disabled and power supplies for radiation detectors turned off, or by providing - a notch filter tuned to block generation of radio frequency interference at the one or more magnetic resonance frequencies of the magnetic resonance scanner.
