20080199059 | Information Enhanced Image Guided Interventions - Linking of interventional and real time ultrasonic information with nonereal time anatomical information of, for example, a vessel or a tumor vascularization provided by x-ray rotational angiography requires high computational performance. According to an aspect of the present invention, an ultrasonic reference image is calibrated with respect to a high quality image acquired by a different imaging system. Then, during operational intervention, a registration or calibration of a data set acquired during the intervention is performed with respect to the reference image and not (as in state of the art devices) to the high quality image. Advantageously, this may allow for a fast fusion of the high quality image with the real time images and therefore allow for an improved tracking of operational interventions performed on a patient. | 08-21-2008 |
20080300588 | Automating the Ablation Procedure to Minimize the Need for Manual Intervention - Cardiac ablation is automated to require minimal user intervention, to thereby reduce X-ray exposure to staff and patients, increase patient throughput, simplify ablation and make ablation more precise. Steering between ablation points on the heart is automatic by use of a localizer system ( | 12-04-2008 |
20090161819 | SYSTEMS AND METHODS FOR SCANNING AND DATA ACQUISITION IN COMPUTED TOMOGRAPHY (CT) APPLICATIONS - Systems and methods for data acquisition in computed tomography (CT) applications are provided. The systems and methods are particularly adapted for scanning and acquiring/processing data in connection with high-power cone-beam CT applications. The electron beam is moved/scanned along the anode surface to multiple focal positions. Data acquisition for a full projection at one focus position and one view angle is achieved by activating each focus position multiple times during the data acquisition for one angle of the gantry. The detector array and associated data processing system are adapted to rapidly switch between the different focus positions during the acquisitions for one view angle and to collect all data belonging to the same projection into the same data set. Adaptive electron optics are utilized to move/scan the electron beam along the anode surface to the various focus positions. Alternatively, a plurality of cathodes may be provided for respective focus positions and the system may support fast switching therebetween to achieve desirably short spot times. The disclosed CT system permits greater power densities without risk of heat damage to the anode and effectively increases the track velocity of the electron beam on the anode surface. The CT system and associated data acquisition methods have particular utility in CT applications requiring increased time resolution and/or spatial resolution, e.g., cardiac CT applications. | 06-25-2009 |
20090177151 | SURGICAL NEEDLE AND METHOD OF GUIDING A SURGICAL NEEDLE - A surgical assembly comprising a needle tip ( | 07-09-2009 |
20090310842 | MODEL-BASED DETERMINATION OF THE CONTRACTION STATUS OF A PERIODICALLY CONTRACTING OBJECT - It is described a model-based estimation of the current contraction status (S) of a periodically contracting object such as a beating heart. Thereby, a characteristic feature that is directly related to the contraction status (S) is extracted from a current image ( | 12-17-2009 |
20100049034 | DEVICE AND METHOD FOR DISPLAYING ULTRASOUND IMAGES OF A VESSEL - The invention relates to a device and a method for displaying a vessel ( | 02-25-2010 |
20100217116 | SYSTEM AND METHOD FOR VISUALIZING HEART MORPHOLOGY DURING ELECTROPHYSIOLOGY MAPPING AND TREATMENT - Systems and methods for facilitating visual detection of one or more catheter tips in relation to the morphology of an anatomical structure—in real-time—are provided. The disclosed systems and methods are particularly useful for locating reference catheters relative to heart tissue using an automated navigation support that draws upon prominent image features that are visible in the x-ray fluoroscopy images. According to exemplary embodiments, prominent features include one or more catheter tips of reference catheter(s) that are typically placed at known standard positions in relation to the anatomical structures. Based on the noted prominent features, the systems and methods of the present disclosure are effective in achieving alignment of the anatomical structures, e.g., the heart morphology, with the interventional devices, e.g., ablation catheter(s) introduced by the physician, and generating a fused or overlaid image. Advantageous computer software products are also disclosed. | 08-26-2010 |
20100262989 | SYSTEM AND METHOD FOR GENERATING INDIVIDUALIZED EXERCISE MOVIES - The present invention relates to a system and a method for generating individualized exercise movies. Generalized exercises are modified by factoring in individual limitations and schedules. The generalized exercises are in a data format that allows their representation for example as avatar movements. The individual limitations also correspond to this data format. After combination of the data a motion sequence is generated which depicts the exercise that the patient should perform but wherein the motion sequence does not display any motions that the patient cannot perform. This motion or video sequence is then viewed by the patient and serves as instruction for his exercises. | 10-14-2010 |
20110156915 | BED EXIT WARNING SYSTEM - There is provided a bed exit warning system for use in monitoring a user on a bed that comprises one or more sensors for measuring one or more physiological characteristics of the user and for producing corresponding signals indicative of the one or more physiological characteristics; and a processor adapted to monitor the corresponding signals and to determine the likelihood that the user is about to get out of the bed from changes in the one or more physiological characteristics. | 06-30-2011 |
20110193699 | USER FEEDBACK ENGINE - There is therefore provided a user feedback engine, comprising a message generation module for generating messages for a user; a queue management module for managing a queue of the generated messages; wherein each message includes respective values for a plurality of parameters including a priority, a period of validity and a non-repeat time; and wherein the queue management module manages the messages in the queue in accordance with the respective values. | 08-11-2011 |
20110296607 | SYSTEM AND METHOD FOR BED HEIGHT ADJUSTMENT - There is provided a control system for an adjustable height bed, the adjustable height bed having a raised position and a lowered position, the control system comprising an input for receiving signals from a sensor located in the adjustable height bed; and a processor for processing the received signals to determine the status of a user relative to the bed and for generating control signals for adjusting the bed to the raised position or to the lowered position on the basis of the determined status. | 12-08-2011 |
