Methods and systems using modeling of crystalline materials for spot placement for radiation therapy
Patent number: 11957934Abstract: A crystalline structure modeling methodology that is conventionally used to model crystalline matter down to the atomic level is instead used to determine spot placement for radiation treatment. The cross-sectional shape of a treatment target is specified; locations (peaks) in a density field inside the shape are determined using the crystalline structure model; locations of spots in the treatment target for spot scanning are determined, where the locations correspond to the locations (peaks) inside the shape determined using the crystalline structure model; and the locations of the spots are stored as candidates for potential inclusion in a radiation treatment plan.Type: GrantFiled: July 1, 2020Date of Patent: April 16, 2024Assignee: SIEMENS HEALTHINEERS INTERNATIONAL AGInventors: Petri Hirvonen, Michiko Rossi, Pierre Lansonneur, Matti Ropo, Viljo Petaja, Perttu Niemela, Timo Koponen -
Patent number: 11938341Abstract: These teachings provide for quickly yet accurately forming an influence matrix by generating the influence matrix via integration with a Monte Carlo particle transport simulation. The resultant influence matrix can then be utilized in an ordinary manner when optimizing a radiation treatment plan. By one approach, the foregoing comprises generating the influence matrix via integration with a Monte Carlo particle transport simulation on a particle-by-particle basis. For example, for each particle, these teachings can provide for identifying a spot to which the particle belongs and then adding a dose deposited by the particle during transport to an influence matrix element that corresponds to a spot to which the particle belongs and a voxel to where the dose was deposited.Type: GrantFiled: December 20, 2021Date of Patent: March 26, 2024Assignee: Siemens Healthineers International AGInventors: Petri Hirvonen, Matti Ropo, Douglas Barnett, Timo Koponen

Patent number: 9712556Abstract: A method and device for preventing a browser-originating attack in a local area network. A security device in the local area network intercepts a message from a first device in the local area network towards a second device in the local area network. The message requests connection between the first device and the second device. The security device prompts a user of the first device to approve the connection. In the event that the user approves the connection the first device is allowed to connect to the second device, and in the event that the user does not approve the connection the connection attempt is terminated.Type: GrantFiled: November 13, 2015Date of Patent: July 18, 2017Assignee: F-Secure CorporationInventors: Timo Hirvonen, Mika Stahlberg

Patent number: 8959641Abstract: A method of foiling a document exploit type attack on a computer, where the attack attempts to extract malware code from within a document stored on the computer. The method includes monitoring the computer in order to detect repeated function calls made by a given process in respect of the same function but different file descriptors; and in the event that such repeated function calls are detected or the number of such repeated function calls exceeds some threshold, terminating the process that initiated the function calls.Type: GrantFiled: May 15, 2013Date of Patent: February 17, 2015Assignee: F-Secure CorporationInventor: Timo Hirvonen
