1. In a computerized system, a method of generating display signals for the presentation of patient image data for a caregiver, comprising:receiving caregiver location data representing the location of the caregiver's head;receiving patient image data from an imaging device in real time, the patient image data representing a subject region of a patient; andgenerating display signals in real time based on the patient image data and the caregiver location data, including: receiving a fixed point on the patient image data; and adjusting the angular orientation of the display signals to maintain a perpendicular relationship between the location of the caregiver's head and the patient image data through the fixed point. 2. The method of claim 1, wherein the step of generating display signals includes adjusting the rotational orientation of the patient image data based on the caregiver location data. 3. The method of claim 2, wherein the step of receiving caregiver location data includes retrieving the caregiver location data from a non-volatile storage device, wherein the caregiver location data represents an average caregiver head location relative to the subject region of the patient. 4. The method of claim 2, wherein the step of receiving caregiver location data includes receiving caregiver height data from a human operator. 5. The method of claim 2, wherein the step of receiving caregiver location data includes tracking the location of the caregiver's head in real time. 6. The method of claim 1, wherein the step of receiving a fixed point on the patient image data includes tracking the location of the tip of a pointer to generate the fixed point. 7. The method of claim 1 wherein the step of receiving a fixed point on the patient image data includes retrieving the fixed point from a non-volatile storage device, wherein the fixed point represents a point of interest of the patient image data. 8. The method of claim 1, further comprising:receiving a display hold signal from an input device operable by the hand or foot of the caregiver; andupon receipt of the display hold signal, holding the state of the display signals without reference to continuing changes in the caregiver location data. 9. The method of claim 1, wherein the patient image data is displayed on a workstation. 10. The method of claim 9, wherein the workstation is a three-dimensional workstation. 11. A system for generating display signals for the presentation of patient image data, comprising:a tracking device configured to track the location of a caregiver's head with respect to a subject region of a patient and to generate location data based on the tracked location;an imaging device configured to acquire an image of a patient and to generate patient image data based on the image; anda computer configured to receive the location data and the patient image data and to generate display signals based on the patient image data and to adjust the angular orientation of the display signals based on the location data and a fixed point on the patient image data to maintain a perpendicular relationship between the location of the caregiver's head and the patient image data through the fixed point. 12. The system of claim 11, wherein the computer is configured to adjust the rotational orientation of the display signals. 13. A system for generating display signals for the presentation of patient image data for a caregiver, comprising:means for receiving caregiver location data representing the location of a caregiver's head;means for receiving patient image data from an imaging device the patient image data representing a subject region of a patient; andmeans for generating display signals based on the patient image data and the caregiver location data, including: means for receiving a fixed point on the patient image data; and means for adjusting the angular orientation of the display signals to maintain a perpendicular relationship between the location of the caregiver's head and the patient image data through the fixed point. 14. The system of claim 13, further comprising means for adjusting the rotational orientation of the patient image data based on the caregiver location data. 15. The system of claim 14, further comprising means for tracking the location of the caregiver's head in real time. 16. The system of claim 2, further comprising means for tracking the location of the tip of a pointer to generate the fixed point. 17. The system of claim 13, further comprising:means for receiving a display hold signal from an input device operable by the hand and foot of the caregiver; andupon receipt of the display hold signal, means for holding the state of the display signals without reference to continuing changes in the caregiver location data. 18. The system of claim 13, wherein the patient image data is displayed on a workstation. 19. The system of claim 18, wherein the workstation is a three-dimensional workstation. 20. In a computerized system, a method of generating display signals for the presentation of patient image data for a caregiver, the method comprising:receiving caregiver location data representing the location of the caregiver's head;receiving patient image data representing a subject region of a patient; andgenerating display signals based on the patient image data and the caregiver location data including:receiving a fixed point on the patient image data; andadjusting the angular orientation of the display signals to maintain a perpendicular relationship between the location of the caregiver's head and the patient image data through the fixed point. 21. A method according to claim 20, wherein the step of generating display signals further includes adjusting the rotational orientation of the patient image data based on the caregiver location data. 22. A method according to claim 21, wherein the fixed point represents a point of interest of the patient image data. 23. A method according to claim 21, wherein the patient image data is received from a database and displayed on a workstation.
