Section: claims

1. A transmission source loading apparatus for an imaging system utilizing a transmission source, comprising:a storage container for storing the transmission source; anda translation device, the translation device being adapted for advancing the transmission source from the storage container into a holder device for use of the imaging system, wherein the advancement of the transmission source is caused by a linear movement of the translation device without any rotational movement thereof. 2. The apparatus of claim 1, wherein an access door is located proximate to the storage container, the translation device being adapted for advancing at least a first portion of the transmission source into the holder device through an access port exposed by displacing the access door. 3. The apparatus of claim 2, wherein the translation device further includes:a drive assembly; anda source gripping device for retaining at least a second portion of the transmission source, the drive assembly being adapted for advancing the source gripping device to a loading point proximate to the access port. 4. The apparatus of claim 3, wherein the source gripping device includes:a housing;a first magnet portion fixed to the housing, the first magnet portion having a first magnetic holding force; andan electromagnet portion fixed to the housing, the electromagnet portion producing a second magnetic holding force when activated. 5. The apparatus of claim 4, wherein the holder device includes:a housing;a source receiving portion disposed in the housing; anda third magnet portion fixed to the housing, the third magnetic portion having a third magnetic holding force. 6. The apparatus of claim 5, wherein the third magnetic holding force is greater than the first magnetic holding force. 7. The apparatus of claim 6, wherein the holder device and source gripping device are adapted for alignment at the loading point such that when the at least first portion of the transmission source is advanced into the source receiving portion of the holder device, the third magnetic holding force being greater than the first magnetic holding force, the transmission source is retained by the source receiving portion of the holder device. 8. The apparatus of claim 5, wherein the first magnetic holding force and the second magnetic holding force combined are greater than the third magnetic holding force. 9. The apparatus of claim 8, wherein the holder device and source gripping device are adapted for alignment at the loading point such that when the transmission source is advanced into the source receiving portion of the holder device, the first magnetic holding force and the second magnetic holding force combined being greater than the third magnetic holding force, the transmission source is retained by the source gripping device. 10. The apparatus of claim 3, wherein the drive assembly includes:a carriage mounted on a lead screw, the carriage controllably translated along the lead screw by a control portion. 11. The apparatus of claim 10, wherein the control portion includes a servo motor. 12. The apparatus of claim 10, wherein the source gripping device is mounted on the carriage. 13. The apparatus of claim 3, wherein the source gripping device and at least a portion of the drive assembly are housed within the storage container. 14. The apparatus of claim 2, wherein the access door is coupled to a door drive assembly, the door drive assembly being adapted for displacing the access door to expose the access port. 15. The apparatus of claim 14, wherein the door drive assembly includes:a door mount fixed to the access door;a track assembly; anda control device being adapted for controllably displacing the door mounted along the track assembly. 16. The apparatus of claim 15, wherein the control device includes a pulley timing belt system coupled to the door mount for controllably displacing the access door. 17. The apparatus of claim 1, wherein the translation device is adapted for advancing the transmission source from the storage container into the holder device along a single axis of motion. 18. The apparatus of claim 1, wherein at least a portion of the translation device is housed within the storage container when the transmission source is in storage. 19. The apparatus of claim 1, wherein the translation device is engaged with the transmission source when the transmission source is in storage. 20. A transmission source loading apparatus for an imaging system utilizing a transmission source, comprising:means for storing the transmission source; andmeans for advancing the transmission source from the storage means into a means for rotating the transmission source for use of the imaging system, wherein the advancement of the transmission source is caused by a linear movement of the advancing means without any rotational movement thereof. 21. The apparatus of claim 20, wherein an access door is located proximate to the storage means, the means for advancing the transmission source being adapted for advancing at least a first portion of the transmission source into the means for rotating through an access port exposed by displacing the access door. 22. The apparatus of claim 20, wherein the means for advancing the transmission source is adapted for advancing the transmission source from the storage means into the holder means along a single axis of motion. 23. The apparatus of claim 20, wherein at least a portion of the advancing means is housed within the storage means when the transmission source is in storage. 24. The apparatus of claim 20, wherein the advancing means is engaged with the transmission source when the transmission source is in storage.
