Next Generation Contextual Advertising Platform Advertising platforms must attract a buyer to the goods being sold by the seller. Currently there are too many middlemen who are part of advertising solutions, seemingly “facilitating” this function. However, in the process they reduce the efficiency, increase the cost and increase the indirectness of the operation resulting in misunderstanding of the buyer's intent. Internet and Web has removed the “middlemen” from several other industries: travel agents, real estate agents, placement agents, etc. We propose a platform for advertising that attempts to do the same.

• Details of machine and problem
• Optimization formulation
– modeling dose
– shot/target optimization
• Results
– Two-dimensional data
– Real patient (three-dimensional) dataThe Gamma Knife201 cobalt gamma ray
beam sources are arrayed in
a hemisphere and aimed
through a collimator to a
common focal point.
The patient’s head is
positioned within the
Gamma Knife so that the
tumor is in the focal point
of the gamma rays.What disorders can the
Gamma Knife treat?
• Malignant brain tumors
• Benign tumors within the head
• Malignant tumors from elsewhere in
the body
• Vascular malformations
• Functional disorders of the brain
– Parkinson’s diseaseGamma Knife Statistics
• 120 Gamma Knife units worldwide
• Over 20,000 patients treated
annually
• Accuracy of surgery without the cuts
• Same-day treatment
• Expensive instrumentHow is Gamma Knife
Surgery performed?
Step 1: A stereotactic head
frame is attached to the
head with local anesthesia.Step 2: The head is
imaged using a MRI or
CT scanner while the
patient wears the
stereotactic frame.Step 3: A treatment plan is developed using the
images. Key point: very accurate delivery
possible.Step 4: The patient lies on the treatment
