Embodiment Construction

[0029] Figure 1A An exemplary radiation therapy system 100 is shown in accordance with various embodiments of the invention. Radiation therapy apparatus 100 may include a therapy device 102 that, when activated, emits one or more ionizing beams aimed at a target area 104 . For example, treatment device 102 may include two X-ray generators 106, 108 that each generate an ionizing beam; the two ionizing beams together form a constructive, high-intensity focused beam of sufficient energy to cause target region 104 to become necrotic. The treatment device 102 may for example comprise a linear accelerator, a synchrocyclotron or preferably an X-ray linear accelerator. The therapeutic device 102 is readily available in the market.

[0030] The radiation therapy apparatus 100 may also include a motion compensation device for adjusting the relative positions of the treatment device 102 and the patient so that the ionizing beam can be continuously focused on the target area even during...

Abstract

An approach for enhancing radiation treatment of target tissue includes identifying a target volume of the target tissue; causing disruption of vascular tissue in a region confined to the target volume so as to define the target volume; based at least in part on the disruption of the vascular tissue, determining a radiation treatment plan having a reduced radiation dose for treating the target tissue; and exposing the target volume to the reduced radiation dose based on the radiation treatment plan.

Description

technical field [0001] The present invention relates generally to radiation therapy, and more particularly, to systems and methods for reducing tissue stress and improving positional tolerances when performing radiation therapy. Background technique [0002] Radiation therapy has been at the forefront of developments in cancer treatment over the past century. Minimally invasive physiotherapy is capable of treating even diseases in which tumors are mixed with normal tissues, and it also allows flexible adjustment of the dosing regimen according to the characteristics and extent of the disease and for each patient. In practice, a radiation facility (eg, a linear accelerator or "linac") emits beams of ionizing radiation at one or more target tumors; the ionizing radiation damages the DNA of tumor cells and thereby kills them. Despite its effectiveness, various challenges remain. [0003] For example, high intensities are required to ensure that sufficient radiation reaches th...
