Another good link Mel, thank you.

One of the issues that always interests me

is how to target the gland when radiating it so that the dose hits the gland

and does not go beyond to damage other organs. I have read of various ways this

is done – Loma I know use a balloon to stabilize the gland –

hence the Brotherhood of the Balloon created by alumni from that institution. Other

methods include implants into the gland that show up on MRI scans.

In the piece you link to here, it is said:

<snip> The CyberKnife, …. is

the only stereotactic radiosurgery system that uses the body's skeletal

structure as a reference point without the use of invasive restraints. Preoperative CT

images are used to define the spatial relationship between the patient's bone

structure and the lesion, creating the computerized 3-D maps that will guide

the machine.

" The tracking technology was modeled

after the military technology of a cruise missile, ……. You make a

map of the patient's anatomy, and the computer's robot drive compares that with

real-time scans of the body during treatment to ensure that the beams hit only

the target and nothing else. "

Before radiation beams are delivered, the

system's X-ray cameras take images to detect any patient movement. These

radiographs will show any shifts in bony landmarks, which in turn are used to

determine changes in the target location based on the landmarks' previous

sites.

Based on the computer's analysis of the

X-ray images, the highly mobile and dexterous robotic arm automatically

compensates for changes in target position during treatment to ensure accurate

delivery of each radiation beam. <snip>

And in the Q & A site, it is said

<snip> The CK system using a unique

robotic mechanism that allows for targeting of the prostate, even as it moves

due to air in the rectum or urine filling the bladder. No other system has that

capability and results in sub-millimeter accuracy. Jerome J. Spunberg, M.D.,

FACR, FACRO Cyberknife Center Of Palm Beach <snip>

I wonder how well this works? On the one

hand they say that the tracking system works by referring to the skeletal

structure as a reference point and that’s fine for when there is a

movement in the structure but but the gland moves relative to the structure –

how is that tracked. To extend the comparison they make, a cruise missile may

accurately hit a pre-programmed target (although there are some doubts about

the accuracy level claimed but if the target is moving, I don’t think the

cruise missile system tracks that.

It is a tragedy of the world that no one

knows what he doesn’t know, and the less a man knows, the more sure he is

that he knows everything. Joyce Carey
