a controller connected to and collecting images from the camera; and

a display in electronic communication with the controller or the camera for displaying medical instrument data pertaining to the movement and position of the plurality of medical instruments;

wherein the controller uses the camera to track medical instrument data including one or more of location, velocity or speed of travel, vector or direction of travel, and telemetry; and

wherein the controller uses the medical instrument data to provide an improved predictive analysis of where a missing medical instrument is likely to be should one of the plurality of medical instruments go missing.

2. The apparatus of claim 1 further including an alarm for indicating at least one of the following alarm conditions:

a medical instrument missing from all of the physical zones;

a medical instrument detected in an undesired zone;

a medical instrument detected in a zone for too long of a time period;

a medical instrument moved out of a predetermined order established for the medical procedure involved; and

/or

a medical instrument moved out of a predetermined order established for the medical personnel involved.

3. The apparatus of claim 2 wherein the controller and/or display includes a user interface for suspending or delaying the alarm.

4. The apparatus of claim 3 wherein actuation of the user interface not only suspends or delays the alarm, but causes the display to display additional information relating to the alarm condition including at least one of a medical instrument position, location, velocity or speed of travel, vector or direction of travel, telemetry and/or instrument marker data.

5. The apparatus of claim 3 wherein the instrument markers include a machine readable marking comprising at least one of:

a bar code;

a RFID sensor;

a UPC, EAN or GTIN;

an alpha, numeric or alpha-numeric sequential marking; and

/or

an easy coding scheme that is readily identifiable by a human for redundant checking purposes.

6. The apparatus of claim 1 wherein the plurality of medical instruments each have an instrument marker and the controller is capable of tracking movement and detecting position of the plurality of medical instruments from their respective instrument markers.

7. The apparatus of claim 6 wherein the instrument marker and controller interact as an orientation agnostic system that is capable of tracking movement and detecting position of the plurality of medical instruments via the instrument marker regardless of what orientation or position each medical instrument or instrument marker is in at any given time.

8. The apparatus of claim 6 wherein the instrument marker is hydrophobic to improve machine readability of the instrument marker.

9. The apparatus of claim 1 further including machine detectable zone markers for delineating the physical zones.

10. The apparatus of claim 9 wherein the machine detectable zone markers have first and second sides, with machine readable information on the first side and a fastener on the second side for fastening the machine detectable zone markers to a surface, the fastener including at least one of:

an adhesive;

a hook or loop fastener portion;

a clasp or clamp;

a zipper; and

/or

a thread.

11. The apparatus of claim 9 wherein the machine detectable zone markers include a machine readable marking comprising at least one of:

a bar code;

a RFID sensor;

a UPC, EAN or GTIN; and

/or

an alpha, numeric or alpha-numeric sequential marking.

12. The apparatus of claim 9 wherein the zone markers are formed on medical drapes or coverings for at least one of a surgical instrument table, patient, operating table or patient support, surgical equipment, and/or waste container.

13. The apparatus of claim 1 wherein the camera both continually tracks movement and detects position of the plurality of medical instruments and the display displays specific data pertaining to both the spatial movement and position of the plurality of medical instruments.

14. The apparatus of claim 13 wherein the specific data pertaining to spatial movement includes tracking at least two of a x coordinate, a y coordinate and/or a z coordinate of the at least one of the plurality of medical instruments and the specific data pertaining to location includes an identification of what zone the at least one of the plurality of medical instruments is currently located.

15. The apparatus of claim 1 wherein the physical zones further include a third physical zone for medical procedure discards.

16. The apparatus of claim 1 wherein the apparatus includes a user interface for locating a missing medical instrument from the plurality of medical instruments.

17. The apparatus of claim 16 wherein the user interface is at least one graphical user interface located on the display that, when actuated, the controller displays on the display an image or video of the missing medical instrument prior to the missing medical instrument going missing to assist with locating the missing medical instrument.

18. The apparatus of claim 17 wherein the controller is configured such that a single actuation of the at least one graphical user interface allows video of the missing medical instrument to be pulled-up on the display and queued up to a period of time at or near when the missing medical instrument went missing which a user can review and replay as desired.

19. An apparatus for tracking medical instruments, comprising:

a medical tracking device having a camera, a display and a control circuit with a non-transitory computer readable memory storing a set of instructions executable by the control circuit and configured to cause the control circuit to perform the steps of;

continuously tracking at least one of a plurality of medical instruments via the camera;

automatically updating the display with current information regarding the position and location of the at least one of a plurality of medical instruments; and

providing an improved predictive analysis of where a missing medical instrument is likely to be should one of the plurality of medical instruments go missing.

20. An item tracking system comprising:
