摘要：
A computed tomography imaging method includes receiving an analog beam intensity signal from a computed tomography scanner and converting the signal into a series of digital representations of the signal at successive points in time using a predetermined sample rate. Indications that a portion of the scanner has reached a certain position relative to the beam are received asynchronously with respect to the sample rate. The value of at least one of the digital representations is adjusted in response to the indications to obtain a corrected digital representation of the analog signal.
