Patent ID: 8886282

Claim:
A system for measuring a magnetocardiogram (MCG) of a small animal using a SQUID sensor, comprising: a case; the SQUID sensor located and fixed inside the case to detect magnetism; a platform arranged near the SQUID sensor inside the case, the small animal being placed thereon; a linear station fixed to the platform and configured to move a location of the platform; and a control unit, wherein the control unit outputs control signals to control operations of the SQUID sensor and the linear station and the control unit measures the MCG of the small animal using intensities of the magnetism detected by the SQUID sensor, wherein the linear station moves the platform in three axial directions X, Y and Z in response to the one or more control signals output from the control unit, and wherein the control unit outputs the one or more control signals to the linear station in order to position the platform to measure MCGs from a plurality of latticed locations on the platform on which the small animal is placed, detects respective maximum absolute values in one direction and the other direction on the basis of a set X-coordinate from among values of the measured MCGs, calculates a plurality of points at set angular intervals from any one of the coordinates at which the maximum absolute values are detected on the circumference of a virtual circle having a diameter corresponding to a straight line connecting coordinates of the detected maximum absolute values, and sequentially outputs a plurality of movement control signals to the linear station in order to measure values of the MCGs from the plurality of calculated points on the circumference.
