Patent number: 11548069Abstract: A 3D printer successively fuses sheet material in a stack to form a three-dimensional object. The sheet material may provide a mesh separating islands of material that will be fused to produce the desired three-dimensional object.

Patent number: 9981312Abstract: A 3-D printer scalable to large sizes employs a combination of mechanical and electrical scanning of a linear array of electron beams that operate to melt material of a powder bed. A housing holding the electron beam sources may be maintained at a high vacuum and positioned close to a print surface to minimize electron travel in a softer vacuum surrounding a print bed.Type: GrantFiled: May 11, 2015Date of Patent: May 29, 2018Assignee: Wisconsin Alumni Research FoundationInventors: Thomas Rockwell Mackie, Brandon Joseph Walker

Patent number: 7450688Abstract: The present invention provides a support for a patient undergoing radiation therapy that preserves radiation build-up, such as normally spares the skin from receiving high amounts of radiation dose. The support includes at least one gas-filled bladder that displaces some tissue from the path of the radiation and/or spaces the tissue being treated from foam or the like.Type: GrantFiled: July 21, 2006Date of Patent: November 11, 2008Assignee: Wisconsin Alumni Research FoundationInventors: Stewart John Becker, Thomas Rockwell Mackie

Patent number: 5724400Abstract: A radiation therapy machine has a constrained angular freedom to produce a beam only within a gantry plane. A radiation shield may be stationary and not attached to the gantry or rotating to always block the primary beam. The constrained motion reduces the risk of patient/gantry collision and provides for extremely accurate radiation therapy planning. The therapy machine, so constrained, may include a tomographic imaging system on a single gantry. The two systems cooperate and employ many of the same hardware components to both plan and carry out therapy sessions in which irregularly shaped treatment volumes are accurately irradiated while tissue surrounding those volumes is minimally irradiated.Type: GrantFiled: January 25, 1996Date of Patent: March 3, 1998Assignee: Wisconsin Alumni Research FoundationInventors: Stuart Swerdloff, Thomas Rockwell Mackie, Timothy Holmes

Patent number: 5661773Abstract: A human interface to be used with irradiation machine in a computed tomography machine wherein x-ray computed tomography images are individually display on a computer screen and an operator uses a manual cursor control device to trace various irradiation zones on the image, identify desired dose within each zone, verify the accuracy of the therapy treatment plan prior to an irradiation session, and verify irradiation delivered after a therapy treatment session.Type: GrantFiled: June 7, 1995Date of Patent: August 26, 1997Assignee: Wisconsin Alumni Research FoundationInventors: Stuart Swerdloff, Thomas Rockwell Mackie, Timothy Holmes
