1. A biomedical system for tracking motion of an object during biomedical imaging and for compensating for motion of the object, the biomedical system comprising:

  • a biomedical imaging scanner configured to perform scanning of the object to generate biomedical images of the object;

    at least one detector for generating data describing at least a first landmark and a second landmark of the object, wherein the at least one detector is configured to be positioned relative to the object to enable the at least one detector to detect movement of the first landmark and the second landmark during the scanning;

    one or more computer readable storage devices configured to store a plurality of computer executable instructions; and

    one or more hardware computer processors in communication with the one or more computer readable storage devices and configured to execute the plurality of computer executable instructions in order cause the biomedical system to;

    utilize a first motion tracking technique to determine motion of the first landmark;

    utilize a second motion tracking technique to determine motion of the second landmark;

    apply a first weighting factor to the determined motion of the first landmark, wherein the first weighting factor is based on a historical accuracy of the first motion tracking technique;

    apply a second weighting factor to the determined motion of the second landmark, wherein the second weighting factor is based on a historical accuracy of the second motion tracking technique;

    determine motion of the object based on analyzing the determined motion of the first landmark and the second landmark;

    generate motion tracking data of the object; and

    control at least one parameter of the biomedical imaging scanner to adjust scanner parameters based on the motion tracking data, the scanner parameters configured for controlling the biomedical imaging scanner to account for motion of the object during the scanning of the object.
