Abstract:
A system and method of treating tachycardias and similar syndromes by the use of catheter ablation of scar tissue is described. The patient is imaged by an X-ray device and an MRI device and the images are fused so as to facilitate identification of scar tissue. The fused image or the X-ray image with treatment areas identified is used to guide the positioning of a catheter with respect to the location to be treated. Guidance of the catheter may be use of X-ray images of the catheter tip, or acoustic or magnetic sensors. After positioning, the catheter is used to ablate body tissue. A further MRI image may be obtained to evaluate the results of the treatment.
Abstract:
Three-dimensional image datasets are used to assist in the visualization of an interventional procedure. The three-dimensional image datasets are registered to two-dimensional images acquired by a medical imaging device. A display device can display a fusion visualization of the three-dimensional image datasets and the two-dimensional image. A monitoring device can monitor the progress of a medical instrument used in the interventional procedure. A processor can incorporate the position of the medical instrument in the fusion visualization displayed by the display device.
Abstract:
A treatment suite and method of use is described, having a digital imaging modality mounted to a first robot. A patient support apparatus mounted to a second robot. The robots cooperate to position a patient with respect to the imaging modality to obtain digital image data of an abdominal area so as to produce computed tomography images, including angiographic, soft tissue or hard tissue images. A third robot has a forcer configured to apply a force to a body part during the imaging process. Contrast agents may be administered during the imaging process. After diagnosis, the treatment of the patient may be performed without moving the patient from the patient support apparatus.
Abstract:
A medical treatment suite is described, having one or more imaging modalities, such as a X-ray, computer tomography (CT) magnetic resonance imaging (MRI), or the like, with additional sensors such as ultrasound imaging, a patient motion sensor, a body parameters monitor, a blood chemistry monitor and imaging processing modules or functions such that a composite image from the image sensors and other patient information from the sensors may be displayed for the purpose of identifying a type of stroke in a patient. After determining the type of treatment protocol to be used, the treatment suite may be used to monitor the administration of the treatment and the patient condition. The sensors communicate with the treatment suite by data interface, and the data obtained by the treatment suite may be transmitted to a remote location for viewing or storage.
Abstract:
A recording arrangement of an x-ray system comprises an x-ray source and an x-ray detector. Adjustment parameters can be manually supplied to the recording arrangement by an operator of the x-ray system, so that the x-ray source emits x-rays according to the manually given adjustment parameters and the x-ray detector accordingly acquires a sequence of images of an object. The manually supplied adjustment parameters can be automatically acquired by an acquisition device and stored in a remanent memory at least temporarily assigned to the acquisition device and remain stored after the completion of the acquisition of the sequence independently of a further operation of the x-ray system. The stored adjustment parameters can be retrieved from the remanent memory by the operator and supplied again to the recording arrangement so that a further sequence of images can be acquired according to the retrieved adjustment parameters.
Abstract:
There is described an X-ray diagnostic device for performing cephalometric, dental or orthopedic examinations on a patient who is seated or standing. The X-ray diagnostic device comprises an X-ray emitter and an image detector embodied as a flat-panel detector that are arranged situated opposite each other on an orbitally moveable mount. The X-ray diagnostic device further comprises means for adjusting the height of the X-ray emitter and the image detector, a digital image system for recording a projection image using rotation angiography, a device for image processing for reconstructing the projection image into a 3D volume image; and a device for correcting physical effects or artifacts for representing soft tissue in the projection image and in the 3D volume image reconstructed therefrom.
Abstract:
A pacemaker comprises an implantable pacemaker housing and a pacemaker electrode which is provided for the transmission of stimulation pulses. A switching element, in particular a reversibly actuatable switching element, is provided for interrupting, reducing or limiting a current flowing through the pacemaker electrode, said current being inducible by an external magnetic field. Parts of the pacemaker are coated with a material, in particular a nanostructured material, which counteracts magnetic effects.
Abstract:
Method of positioning a mobile X-ray detector unit of an X-ray system, X-ray system and mobile X-ray detector unit.method is described for positioning a mobile X-ray detector unit (25, 26) of an X-ray system (1). The X-ray system (1) deployed has X-ray radiation units (5, 6, 7) and at least one mobile X-ray detector unit (25, 26). The X-ray radiation units (5, 6, 7) thereby each have an active and a passive operating status. The X-ray radiation units (5, 6, 7) are each assigned a detector holder (8, 9, 10, 11, 12) to hold a mobile X-ray detector unit (25, 26). To generate X-ray recordings, X-ray radiation emitted by an active X-ray radiation unit (5, 6, 7) is detected by means of a mobile X-ray detector unit (25, 26), which is located in a detector holder (8, 9, 10, 11, 12) of said X-ray radiation unit (5, 6, 7). A mobile X-ray detector unit (25, 26) is positioned as a function of the operating status of the X-ray radiation units (5, 6, 7) such that a mobile X-ray detector unit (25, 26) is located in each of the detector holders (8, 9, 10, 11, 12) assigned to the active X-ray radiation units (5, 6, 7). A location unit is used to determine the location of a mobile X-ray detector unit automatically.

Catheter device for performing atherectomy, comprising an atherectomy catheter, an OCT sensor, an IVUS sensor, position sensors and an image processing unit, which is embodied for creating combined 2D and/or 3D images based on the data of the sensors.
Abstract:
In a method and an apparatus for conducting a medical procedure on a number of patients respectively disposed at a number of different locations, a component of a medical device for implementing the medical procedure is moved along a pre-assembled track that extends to each of the locations. When the component is moved to the intended location by the track, the medical procedure is implemented at that location with the component retained on the track.
