Abstract
A representative method for determining a zero baseline value of a channel from a detector device of a nuclear medicine imagining system to allow for correction caused by noise or interference on the detector device includes calculating a first value of a baseline based on a first sample of analog electrical signals from analog-to-digital converters (ADCs) coupled to the detector device; comparing a predetermined value with the first value of the baseline; determining whether there is a small change between the predetermined value and the first value of the baseline; and responsive to determining that the small change exists, adjusting the baseline of the ADCs by a fraction of the small change based on the comparison between the predetermined value and the first value of the baseline.
