How long are CyberKnife treatments? Dr. Curtis Worthington: Well they are highly variable. It depends on the complexity of the abnormality and how closely involve it is with normal structures. Once the appropriate case is identified, that individual then will have to have some imaging done usually with CT and MR, possibly some other things. It's the surgeon's role to then identify the exact size and geometry of the tumor and also to identify the critical important structures around it. It's a lot like actually doing an operation except on the computer. An open operation you are going to be very cognizant of normal areas that you need to protect and the abnormal area that you need to remove. So put all this information on the computer and sit down and with the physicist generate a doze plan that we then give to the machine and sort of tell the machine even an all its intelligence how to go about carrying the procedure out. If it's very complex it may take several hours, if it's relatively simple, then it can take as little as 30 minutes, so it's quite variable.
