Abstract:
Systems and methods for synchronizing machine-induced expiratory airflow of a subject with user-induced expiratory airflow include an indicator time at which a user should initiate treatment to aid airway clearance of the subject. Such treatment may include compressing the stomach area of the subject. At the indicator time, a user responds to an indication, e.g. an audible sound,by initiating treatment in accordance with a therapeutic regimen.
Abstract:
A digital processing device (14, 14') has first and second independent communication links with a local medical information system (10) and an Internet-based electronic health record (EHR) account (12) of an individual, respectively. The digital processing device presents a first window (W1) indicating content pertaining to the individual stored at the local medical information system and a second window (W2) indicating content stored at the EHR account. A selection (D1, D2, S4, S14) of content to transfer from the EHR account of the individual to the local medical information system or vice versa is received. The selected content is transferred via one of the first or second communication link to an isolation container (50) at the digital processing device, and is transferred via the other of the first or second communication link from the isolation container to the destination local medical information system or EHR account..
Abstract:
This invention provides a method and a system for detecting a plurality of markers worn on the body of a user. The basic idea is to make the motion of the markers different from the motion of the interference points and then to distinguish the interference points from the markers on the basis of the motion information. By outputting the first action indication, it is possible to make the user move the markers in a way different from the status of the stationary or moving interference points. If there are interference points among the detected regions of interest, the motion information of the markers will be different from the motion information of the interference points and then the interference points can be distinguished from the markers on the basis of the motion information. Therefore, the accuracy of marker identification can be improved and by virtue thereof the accuracy of motion capture of the user can be improved.
Abstract:
The invention relates to a radiation detector (100) comprising a converter element (102) for converting incident high-energy radiation (X) into charge signals. A cathode (101) and an array(104) of anodes (103) are disposed on different sides of the converter element(102) for generating an electrical field (E 0, E d ) within it. The strength of said electrical field(E 0, E d ) is increased in a first region(R d ) near the anode array(104) with respect to a second region(R 0 ) remote from it. Such an increase may be achieved by doping the first region(R d ) with an electron acceptor. The increased field strength in the first region(R d ) favorably affects the sharpness of charge pulses generated by incident radiation.
Abstract:
The insertion of a needle or other surgical instrument into the body is guided by three dimensional ultrasonic imaging. A probe having a two dimensional array transducer is placed against the body and manipulated to acquire an image of the site of the surgical procedure inside the body. The clinician inserts the surgical instrument, trying to follow an insertion path which is in the plane of a single image produced by the ultrasound system. The clinician observes the path of insertion and insertion progress on a display of a plurality of real-time 2D ultrasound images of spatially adjacent planes of a volume including the surgical procedure site. If the insertion path of the instrument does not remain in the plane of a single image, portions of the instrument will appear in the images of multiple adjacent image planes when the instrument intersects a succession of image planes as it progresses toward the site of the surgical procedure.
Abstract:
A system and method for ablation planning includes defining (502) shapes and sizes for one or more ablation volumes based on probability of treatment, and determining (510) a target volume to be treated. A procedure plan is provided (516) by determining a number and location of planned ablations within the target volume using the one or more ablation volumes. A joint probability distribution (520) is determined for at least two planned ablations in the target volume. A final configuration is visualized (530) to determine if plan objectives are met based on a probability of treatment for the target volume.
Abstract:
A replaceable unit (102) for use with an apparatus(100) that determines the level of nitric oxide in exhaled breath is described. The replaceable unit (102) comprises a conditioning section (116) for reducing the amount of water in air (124) exhaled by a user to produce a conditioned sample of air(130) for use in nitric oxide to nitrogen dioxide conversion.
Abstract:
The invention relates to a tumble disc bearing (100) to provide an efficient axial bearing for a rotating anode (216) of an X-ray source (212) having a tumble disc (102) for axially bearing the rotating anode (216), and a mounting component (120) for supporting the tumble disc (102). The mounting component (120) comprises an inner mounting face (122) for attaching to a supporting structure (194, 204). The mounting component (120) is supported in the tumble disc (102) at a tumble position (140) in which an inner supporting face (104) of the tumble disc (102) matches an outer supporting face (124) of the mounting component (120) such that the tumble disc (102) is enabled to perform a tumble motion in all directions in relation to the mounting component (120). The mounting component (120) is adapted to be inserted in an inserting position (142) traverse to the tumble position (140) into the tumble disc (102). At least one recess (110, 610) at the tumble disc (102) is provided for inserting at least one catch (150, 650) in an axial direction (160) of an anode rotation axis (162) and for engaging with the at least one catch (150, 650) to fixate the tumble disc (102) against a rotational movement (164) in relation to the support structure (194, 204) while maintaining the tumble motion of the tumble disc (102).
