Radiation Therapy with Orthovoltage x rays and a Special Collimator
Method of therapeutic radiation delivery for a specific target using a multi-aperture collimator within a trajectory of orthovoltage x-rays Background: Current radiation therapy is carried out using mostly high energy x-rays. The current MeV x-rays being used have good qualities such as high tissue penetration and a â€œskin-sparing effect.â€ Despite this, several drawbacks are associated with this method; most importantly, the tissue surrounding the target receives radiation, which is damaging to the tissue. These high energy x-rays interact in a scattering mode rather than a photoelectric one, which would be more confined within the target. To address this issue, a â€œgrid theoryâ€ was developed using orthovoltage x-rays. These techniques would be beneficial if they offered tissue-sparing to healthy tissue near the target tissue; without this quality, it doesnâ€™t solve the issue of damaging normal tissue. A need for a method of radiotherapy using orthovoltage x-rays for effectively treating tumors is necessary, but the skin and tissue surrounding the target tissue must be spared in order for this method to be effective. Technology Overview: This technology is a system and method for treating a tumor while sparing the surrounding healthy tissue; it uses orthovoltage x-ray radiation. This technology also discloses how to control the tissue depth reached by the radiation, which is essential in order to protect surrounding healthy tissue. This system uses a multi-aperture collimator near the surface of the skin; this lies within a trajectory of radiation, and generates an array of minibeams, which are designed to merge, forming an effective radiation beam. Advantages: - Low-cost radiotherapy - Compact solution for radiotherapyÂ - Controlled beams of radiation to minimize damage of surrounding tissueÂ - Tissue depth can be varied from around 1 cm to 10 cm - Beam broaden to less than 1.0 mm during merging process - Angular position of the x-rays can be changed to hit target from different angles Applications: - Treatment of tumors - Treatment of neurological targets, such as: - Brain tumors - Disorders, such as epilepsy and alzheimers Intellectual Property Summary: Patented Stage of Development: 10124194 Licensing Potential: Development partner,Commercial partner,Seeking investment Licensing Status: Available for partnership.Â R-8592 Additional Information: radiation,radiation therapy,x-ray,collimator,radiation oncology,medical radiation,beam radiotherapy,radiotherapy,radiotherapy treatments,brain cancer,brain tumour,brain tumor,tissue penetration,photoelectric,skin tissue,neurological,epilepsy,alzheimer,microbeam radiation therapy,cancer radiation therapy https://stonybrook.technologypublisher.com/files/sites/nknpkjx5stmjsolwronp_nci-vol-8771-300.jpg Please note, header image is purely illustrative.
