Classification: CPC A  G | IPC A

Claim 0:
1. A device for measuring respiration of a patient, the device comprising:
a positron emission tomography (PET) or single photon emission computed tomography (SPECT) imaging device; and
at least one processor programmed to:
extract a first respiration data signal from emission imaging data of a patient acquired by the PET or SPECT imaging device;
extract a second respiration data signal from a photoplethysmograph (PPG) signal of the patient; and
generate a respiration signal indicative of respiration of the patient,
wherein generating the respiration signal comprises:
determining a time lag of the second respiration data signal respective to the first respiration data signal; and
generating the respiration signal as the second respiration data signal shifted in time to correct the determined time lag.
