Method and apparatus for capture of physiological signals and image data
First Claim
1. A method for acquiring physiological signals and raw data for imaging of a volume segment of an examination subject, comprising:
- from a computer that operates according to a computer time base, operating a medical raw data scanner to acquire medical raw data for imaging of a volume segment of a subject situated in the scanner and acquiring image time stamps at which at least some of the raw data are acquired;
from said computer operating according to said computer time base, operating a physiological sensor to acquire physiological signals from the examination subject simultaneously with acquiring said raw data, and acquiring signal time stamps at which at least some of the physiological signals are acquired;
storing said image time stamps in a predetermined data format in an electronic memory;
storing said physiological signals and the associated time stamps also in the same data format, with each image time stamp and each signal time stamp being stored as an independent entry in said data format; and
making the acquired raw data and physiological signals, and the respective image time stamps and signal time stamps available from the electronic memory, via the computer, in electronic form as a data file.

Abstract
In a method and an image capturing system (5) for capturing signals and image data of a volume segment of an examination object, raw data of the volume segment are captured, and image time stamps are captured at which certain of the raw data are captured. Physiological signals of the examination object are captured at the same time as capturing the raw data. Signal time stamps are captured at which certain of the physiological signals are captured. The capture of the raw data and the capture of the physiological signals is controlled by the same processor of the image capturing system, so that both the image time stamps and the signal time stamps are predetermined by the same processor.
