US Patent:

20090050819, Feb 26, 2009
Filed:

Dec 21, 2005
Appl. No.:

11/720873
Inventors:

Chang Ming Ma - Huntingdon Valley PA, US
Eugene S. Fourkal - Philadelphia PA, US
Jinsheng Li - Maple Glen PA, US
Wei Luo - Chapel Hill NC, US
Assignee:

Fox Chase Cancer Center - Philadelphia PA
International Classification:

H01J 3/14
A61N 5/00
H01F 6/00
US Classification:

250396ML, 2504923, 335216
Abstract:

Compact particle selection and collimation devices are disclosed for delivering beams of protons with desired energy spectra. These devices are useful with laser-accelerated proton therapy systems, in which the initial protons have broad energy and angular distributions. Superconducting magnet systems produce a desired magnetic field configuration to spread the protons with different energies and emitting angles for particle selection. The simulation of proton transport in the presence of the magnetic field shows that the selected protons are successfully refocused on the beam axis after passing through the magnetic field with the optimal magnet system. Dose distributions are also provided using Monte Carlo simulations of the laser-accelerated proton beams for radiation therapy applications.

US Patent:

20180133516, May 17, 2018
Filed:

Nov 15, 2016
Appl. No.:

15/351494
Inventors:

- Xi'an, CN
Jinsheng Li - Huntingdon Valley PA, US
International Classification:

A61N 5/10
Abstract:

The present disclosure discloses a radiation treatment plan generation method, which is applied to a therapeutic equipment comprising at least two therapeutic heads. The method comprises the steps of: acquiring images of an area of the patient with a tumor; determining a treatment target region including the tumor as a region for being irradiated with a radiation beam upon radiotherapy; obtaining a prescription dose of the treatment target, wherein the prescription dose comprises a parameter of prescription dose value that is a magnitude of a dose received by the tumor; and determining a therapeutic head, a therapeutic approach and a therapeutic drive approach suitable for irradiating the target region, based on the therapeutic target region and the prescription dose thereof.
