    Abstract: The present invention relates, in general, to the field of motion tracking, and in particular to join a target in an MRI application. In particular the invention teaches an apparatus and method to track the movement of a target during medical imaging scanning using optical technology. Optical systems record the position and movement of the pattern and are able to perform mathematical analysis of the pattern to determine the positional shift of the patient. Weighted averages, Fourier transforms, Hadamard matrices and cross-correlation of data related to X-Y translation, rotation and scaling of the image of the pattern are used to analyze movement of the subject's head. Feedback related to the movement is provided to the MRI machine which allows for adjustments in focusing coils for real time tracking of the patient's movements during the MRI procedure. As a result, the MRI procedure becomes more accurate as it is adjusted for the patient's movements.

    Abstract: The present invention discloses a method for determining location and movement of a moving object. One embodiment of the method tracks the movement of a target during medical imaging scanning and transmits the position shift to the medical imaging scanning device in real time. The method includes the steps of projecting structured light on the target, receiving the reflection of structured light, converting the received structured light into spatial positions, and transmitting the positional shift to the medical imaging scanning device. The method further includes the step of adjusting the medical imaging scanning device in response to the positional change to increase accuracy.

    Abstract: The present invention discloses an apparatus and method to track the movement of a target. One embodiment tracks the movement of the patient during medical imaging scanning using optical technology. Optical systems record the position and movement of the target and provide inputs to a processor. The processor is capable of performing mathematical analysis of the movement of the target to determine the positional shift of the patient. Weighted averages, phase correlation, Fourier-Mellin algorithms, and cross-correlation of data related to X-Y translation are used to calculate movement of the target subject. Feedback related to the movement is provided to the medical imaging scanning machine which allows for adjustments in focusing coils for real time tracking of the patient's movements during the procedure. As a result, the medical image scanning procedure becomes more accurate as it is adjusted for the patient's movements.

    Abstract: A method and apparatus for diagnosing schizophrenia, schizophrenia disorder subgroup, or predisposition thereto in a test subject is disclosed. The method includes the steps of determining an interhemispheric switch rate of the test subject. In one embodiment, the interhemispheric switch rate of the test subject is under conditions of increasing rate of dichoptic reversal, and comparing the switch rate with a corresponding reference switch rate to diagnose presence or absence of schizophrenia, a schizophrenic disorder subgroup, or predisposition thereto. In a preferred embodiment, the interhemispheric switch rate is determined by measuring the rate of binocular rivalry in the test subject. Also disclosed is use of a diagnostic method in genetic linkage studies for the identification of the molecular defect(s) underlying schizophrenia, and for the identification of compounds which may alleviate the disorder.
