Patent number: 10016627Abstract: The invention provides for a medical apparatus (300, 500, 600) comprising a high intensity focused ultrasound system (302), a memory containing instructions, and a processor. Execution of the instructions causes the processor to receive (100, 202) surface data (342) descriptive of the location of a surface (322). The surface data defines the location of the heating volume. Execution of the instructions further cause the processor to determine (102, 204) a set of transducer switching commands (344) using the heating location data and an ultrasound transducer element model (352) and control (104, 206) the high intensity focused ultrasound system with the set of transducer switching commands to heat the heating volume. The set of transducer switching commands comprises an intensity level for the multiple ultrasound transducer elements either above or below a predetermined intensity for controlling a cross sectional shape of the heating volume to encompass the surface.Type: GrantFiled: June 4, 2013Date of Patent: July 10, 2018Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Antti Johannes Viitala, Mika Petri Ylihautala

Publication number: 20170113070Abstract: It is an insight of the invention that to achieve good treatment efficiency there is a need to minimize the cooling times and while preventing overheating of a subject treated. This object is achieved by a guided thermal treatment system, comprising:—a thermal treatment system configured for applying thermal treatment pulses to a patient, wherein the thermal treatment pulses are spaced in time by a cool-down period,—a guidance system, configured to provide guidance to the thermal treatment, wherein the guidance system comprises a thermal module configured for providing a first and second level of cool-down period, the first level indicating a mandatory part of the cool-down period in which applying of a thermal treatment pulse is prohibited, the second level indicating a recommended part of the cool-down period in which applying a thermal treatment pulse would result in an elevated risk of overheating in a sensitive patient, but not in a non-sensitive patient.Type: ApplicationFiled: March 16, 2015Publication date: April 27, 2017Inventors: JUKKA ILMARI TANTTU, MIKA PETRI YLIHAUTALA, ILPO ASKO JULIUS KOSKELA
