Cancer surface searing apparatus and method of use thereof
First Claim
1. A method for treating a tumor, within healthy tissue of a patient, with positively charged particles, the tumor comprising a tumor surface area and a tumor central volume, the method comprising the steps of:
- accelerating the positively charged particles with a synchrotron to a first energy level;
rotating the patient on a rotational platform;
using a controller linked to said synchrotron and said rotational platform to target the tumor surface area with the positively charged particles, wherein said surface area of the tumor comprises at least one of;
an outer perimeter of the tumor;
portions of healthy tissue contacting the tumor; and
healthy tissue proximate the tumor; and
under control of said controller, delivering a therapeutic dosage of the positively charged particles to the tumor surface area of the tumor and a sub-therapeutic dosage of the charged particles to the central volume of the tumor.

Abstract
The invention comprises a charged particle cancer therapy system used to seal a periphery of a tumor, such as through use of a proton or carbon ion beam searing the outer edges of the tumor, which prevents/hinders nutrient delivery to the tumor resultant in stunted growth of the tumor, halted growth of the tumor, and/or starvation/necrosis of the tumor. Optionally, a tumor sealing layer is formed using multiple passes, of a treatment beam of the charged particle cancer therapy system, across a tumor/healthy tissue boundary layer or voxel.

12. An apparatus for treating a tumor, within healthy tissue of a patient, with positively charged particles, the tumor comprising a tumor surface area and a tumor central volume, the apparatus comprising:
-
a synchrotron configured to accelerate the positively charged particles to a first energy level; a rotational platform configured to hold and rotate the patient; a controller linked to said synchrotron and said rotational platform, said controller configured to target the tumor surface area through rotation of the patient on the rotational platform and control of the positively charged particles from said synchrotron, wherein said surface area of the tumor comprises at least one of; an outer perimeter of the tumor; portions of healthy tissue contacting the tumor; and healthy tissue proximate the tumor; and said controller configured to deliver a therapeutic dosage of the positively charged particles to the tumor surface area of the tumor and a sub-therapeutic dosage of the charged particles to a central volume of the tumor. - View Dependent Claims (13, 14, 15, 16)
