摘要:
The present invention relates to a system (100) for combined ablation and ultrasound imaging of associated tissue (40), which is particularly useful for use in an ablation process. The system comprises an interventional device (20) with an ultrasound transducer and an ablation unit. During an ablation process, the interventional device (20) can be applied for both ablation and imaging of the tissue (40) subject to the ablation. A controlling unit (CTRL) is further comprised within the system, and arranged to calculate a predictor value based on one or more signals from the ultrasound transducer, where the predictor value relates to a risk of impending tissue damage due to a rapid release of bubble energy. According to a specific embodiment, a primary signal is sent if the predictor value exceeds a threshold value, so that proper measures can be taken.

The invention relates to a health management system comprising a body or limb movement detecting means for detecting the movements and position of a users body or limb(s) in 3D space, a movement analyzing means for analyzing the data of the measurement carried out by the body or limb movement detecting means, wherein the body or limb movement detecting means comprises at least three sensors or markers for tracking a user's body or limb movement in 3D space by measuring an angle embedded by two body parts of the user which are connected to each other by a joint being the apex of the angle to be measured, at which one of the sensors or markers is provided. To detect the offset a change in distance between two neighboring sensors or markers indicates an offset of the sensor at the joint spaced apart from the apex.

The invention discloses a sensor docking unit (1), a rehabilitation system and a method for attaching and removing at least one sensor or marker (2a) onto/from a users limb(s) the sensor docking unit (1) comprising a guiding portion (4), a limb localization unit (5) comprising at least one detecting means (6) to determine if an insertion of the users limb (3) into a pre-specified position within the sensor docking unit (1) has been completed correctly and a sensor or marker mounting means (7) including at least one sensor or marker entity (2) to enable an at least semi-automatic attachment and/or removal of the at least one sensor or marker (2a) to/from the users limb (3) in a reproducible manner. The sensor or marker mounting means (7) is activatable to start with an attachment and/or removal of the at least one sensor or marker (2a) when a correct insertion of the users limb (3) has been determined by the limb localization unit (5).
摘要:
A sensor arrangement for home rehabilitation in particular after a stroke comprising at least two sensors. The sensors are attached to the user's body. Each sensor includes—a receiver for receiving a first signal being generated from a source outside the sensor 10 arrangement—a sensor processing unit processing the first signal and initializing a second signal upon reception of the first signal, the second signal including information regarding the identity of the sensor—a transmitter for transmitting the second signal to a central processing unit 15 On receipt of the first and/or the second signal a time stamp is generated for each sensor for a determination of the location of each sensor relative to a source of the first signal trough comparison of the different time stamps.
摘要:
A sensor docking unit for attaching and removing sensor or marker onto/from a user's limb includes a guiding portion and a limb localization unit having a detector to determine if an insertion of the user's limb into a pre-specified position within the sensor docking unit has been completed correctly. A sensor or marker mounting device includes at least one sensor or marker entity to enable at least semi-automatic attachment and/or removal of the at least one sensor or marker to/from the user's limb in a reproducible manner. The sensor or marker mounting device is activatable to start with an attachment and/or removal of the at least one sensor or marker when a correct insertion of the user's limb has been determined by the limb localization unit.
摘要:
Systems and methods are provided for calculating the tilt of an object from a minimum set of measurements. In the described embodiments, one or more accelerometers are used to sense tilt in fewer degrees of freedom than would otherwise be required in a conventional measurement apparatus. In one embodiment, a single axis accelerometer measures 2D tilt by taking into account a constant value of the earth's gravitational field in a direction generally perpendicular to the earth.

An automatic sensor position recognition system including a position recognition unit located at pre-determined positions on a person's body and bearing a unique identification; a sensor bearing a unique identification; a communication unit assigned to the sensor and being in communication with the position recognition unit and the sensor; a data processing unit in communication with the communication unit; and a database being in communication with the data processing system and comprising the correlation of the unique identification of the position recognition unit and the pre-determined position of the position recognition unit. The system provides an automatic association between sensors and body segments as well as means to obtain these associations.
