Abstract

A MOBILE C-ARM X-RAY IMAGER WITH A DOCKING MECHANISM IS PROPOSED FOR USE IN A RADIOTHERAPY TREATMENT VAULT. THE C-ARM IS DOCKED NEAR THE FOOT OF THE LINEAR ACCELERATOR TREATMENT TABLE SO AS NOT TO INTERFERE WITH THE CLEARANCE REQUIRED FOR THE LINAC. TO IMAGE, THE COUCH IS DRIVEN TO A CONSTANT LONGITUDENAL OFFSET, THE IMAGE IS TAKEN. CT RECONSTRUCTION MAY BE USED TO OBTAIN A 3D DATA SET. THE TABLE IS MOVED BACK TO THE TREATMENT POSITION AND CORRECTIONS ARE MADE TO THE POSITION BASED ON ANATOMICAL INFORMATION. THE TREATMENT MAY PROCEED WITH THE C-ARM IMAGER IN THE ROOM OR IT MAY BE DISENAGED AND MOVED INTO A CORNER OF THE ROOM OR MOVED OUT COMPLETELY.
