Patent number: 9072894Abstract: Techniques for radioablation of sympathetic nerves include positioning a subject on a support in view of a volume imaging system and an ionizing radiation source; and collecting volume image data. Location of a treatment portion of a sympathetic nerve in the subject is determined based on the volume image data. Movement of the source is determined to apply a therapeutic radiation dose to the treatment portion based on the location of the treatment portion and relative location of the source to the volume imaging system. The source is operated to deliver the therapeutic radiation dose. An apparatus includes a mounting structure, an X-ray source and a shield. The source produces an X-ray beam with photon energy above one million electron volts (MeV) and not above six MeV. The shield is mounted in opposition to the source to block the X-ray beam with photon energies not greater than about six MeV.Type: GrantFiled: January 14, 2011Date of Patent: July 7, 2015Assignee: The Board of Trustees of the Leland Stanford Junior UniversityInventors: Robert K. Chin, Matthew Thomas Wheeler, Peter G. Maxim

Patent number: 9018603Abstract: A compact high-gradient, very high energy electron (VHEE) accelerator and delivery system (and related processes) capable of treating patients from multiple beam directions with great speed, using all-electromagnetic or radiofrequency deflection steering is provided, that can deliver an entire dose or fraction of high-dose radiation therapy sufficiently fast to freeze physiologic motion, yet with a better degree of dose conformity or sculpting than conventional photon therapy. In addition to the unique physical advantages of extremely rapid radiation delivery, there may also be radiobiological advantages in terms of greater tumor or other target control efficacy for the same physical radiation dose.Type: GrantFiled: November 1, 2013Date of Patent: April 28, 2015Assignee: The Board of Trustees of the Leland Stanford Junior UniversityInventors: Billy Wiseman Loo, Peter G.

Patent number: 8526702Abstract: Improved 4D imaging reconstruction is provided for a freely breathing patient. 3D patient images from an imaging dataset are binned according to respiratory displacement or phase. The bins are defined by ranges, so every image in the raw 3D data set is included in a bin. Since binning in this manner often results in two or more images per bin, the 4D reconstruction is determined by selecting one 3D image from each bin at each patient position. This selection is performed so as to maximize the anatomical similarity of 3D images at adjacent patient positions. In cases where the 3D images include multiple slices, a 2D comparison of the closest slices can be used to determine anatomical similarity of the 3D images.Type: GrantFiled: January 6, 2012Date of Patent: September 3, 2013Assignee: The Board of Trustees of the Leland Standford Junior UniversityInventors: Eric Johnston, Peter G. Maxim, Billy W. Loo, Jr., Maximilian Diehn
