Abstract: The present invention provides a method for heating a target zone (3) of a subject of interest (1) according to pre-defined heating requirements using ultrasonic irradiation, comprising the steps of providing an ultrasonic irradiation device comprising a set of individually controllable transducer elements in vicinity of the target zone (3), defining at least one sensitive zone (2) within an area (4) covered by ultrasonic irradiation device, and controlling the ultrasonic irradiation device to apply sonications of ultrasonic energy to the target zone (3) to achieve the desired heating thereof, wherein the transducer elements are individually controlled in phase and amplitude to provide the sonications as a beam (5) directed towards the target zone (3), wherein the beam (5) has a energy distribution so that the pre-defined heating requirements of the target zone (3) are met and the exposure of the at least one sensitive zone (2) is minimized The present invention further provides an ultrasonic irradiation devi

Abstract: The invention provides for a medical apparatus (500, 700, 800) comprising a high intensity focused ultrasound system (506). The medical apparatus further comprises a memory (550) for storing machine executable instructions (560, 562) for execution by a processor (544). Execution of the instructions cause the processor to: receive (100, 200, 304) previous sonication data (522) descriptive of a previous sonication of the subject; construct (102, 202, 306) a thermal property map (554) of the subject using the previous sonication data and a thermoacoustic model (562); determine (104, 204, 308) a maximum energy map (556) using the thermoacoustic model and the thermal property map, wherein the maximum energy is time dependent; display (106, 206, 310) the maximum energy map on a display (672); and receive (108, 208, 312) a selection of at least one thermoacoustic model and thermal property map sonication volume (580, 582) from a user interface (570).

Abstract: The present invention provides a method, apparatus and system for pre-establishing a secure communication channel by detecting one or more trigger events (302), determining whether the secure communication channel will be needed in the future (304) and establishing the secure communication channel before the secure communication channel is needed (308-316). The secure communication channel is established by sending a SA Query (308) and determining whether the SA Query matches one or more security policies (310). If the SA Query matches the one or more security policies, the present invention determines whether the SA Query matches a SA (314). If the SA Query does not match the SA, a SA is negotiated (318) and a SA Query successful message is returned (316). This method can be implemented as a computer program embodied on a computer readable medium wherein each step is executed by one or more code segments.
