摘要:
A system and method provide an optimized workflow and a dedicated user interface for image visualizations that facilitate medical diagnosis. Image data may be acquired via an imaging procedure at a remote medical facility. A physician may review the images on a display and mark-up/modify the images via the interface to create user-defined data. The image and user-defined data may be transmitted to a service provider. At the service provider, a software technician may generate a medical simulation using the image and user-defined data. The medical simulation may simulate actual conditions within the patient. Subsequently, the simulation results may be transferred to, or otherwise remotely accessed via a network from, the remote medical facility. As a result, medical treatment provided by remote facilities, which may only have limited resources in terms of personnel and equipment, may be enhanced and inefficiencies associated with the generation of medical simulations may be alleviated.
摘要:
The invention relates to a method for evaluating projection datasets of an object undergoing examination. Each projection dataset is assigned a swiveling angle and a recording instant. Each data element of each projection dataset defines a projection line along which an X-ray beam has traveled from an X-ray source to an X-ray detector. The projection datasets form recording groups each of which corresponds with the projection datasets that were recorded during a single swiveling action. A computer determines reconstruction datasets using the projection datasets. Each reconstruction dataset contains at least one reconstruction data value assigned to a reconstruction line. Using a temporal interpolation, the computer determines the reconstruction datasets in such a way that they refer to a uniform reconstruction time. The computer determines a reconstruction of the object undergoing examination using the reconstruction datasets.

摘要:
An optical coherence tomography system includes a catheter in which is arranged a plurality of light conducting fibers. It further includes a plurality of optical units. Light from the proximal end to the distal end and signals from the distal end to the proximal end can be transmitted simultaneously in different fibers. Time is saved through the simultaneous signal processing of signals from different fibers. That is advantageous particularly in the imaging, by means of coherence tomography, of blood vessels that have to be occluded for said imaging.
摘要:
A system and method of treating cancerous tissues using a combination of embolization and ablation therapies is described. An imaging device is used to determine the tissue volume to be treated, and the steps of embolization and ablation are performed while the patient remains on a treatment table. The embolization treatment may be combined with chemotherapy directly administered to the tumor. The position of the volume to be treated is visualized by the imaging device to monitor the progress of the treatment and to guide ablation treatment so as to mitigate collateral tissue damage. The imaging device may be a C-arm X-ray device, a MRI device, an acoustic device or other device capable of producing CT-like images.
摘要:
The invention relates to an interventional medical diagnosis or therapy system comprising: an imaging device, which is embodied for recording 3D images of an object under examination, with a control unit and an image processing unit; an at least two-axis robot arm, having means for yield control of the robot arm and a robot control unit for control of the robot arm; an instrument holder, which is connected to the robot arm, for holding an instrument; a position detection device, by means of which the position of the instrument is able to be detected for the robot control unit. The robot arm is embodied to yield to system-external force effects or to follow a system-external guidance.
摘要:
A system and method of obtaining perfusion data for cerebral tissue is described. The system includes a C-arm X-ray device and a computing system configured to obtain sets of rotational projection X-ray data suitable for reconstructing 3D voxel data sets. A first data set is obtained of the patient, and then contrast material is injected into the vascular system to obtain a second 1 data set. A first voxel data set is subtracted from the second voxel data set, and the resultant data set is processed so as to segment the contrast-enhanced vasculature from the remaining data. The segmented voxels are subtracted from the resultant voxel data set, so as to yield a functional data set representing the difference between the attenuation of the tissues after administering contrast agent and the tissues prior to administering the contrast agent, without the contrast enhanced vasculature. The attenuation of the functional data set represents the perfusion or cerebral blood volume (CBV).

A system and method for an integrated imaging system with magnetic resonance imaging (“MRI”) and optical coherence tomography (“OCT”). The system includes an MR scanner and OCT device configured to generate images. The system is further operative to assist a clinician in intravascular interventions, endoluminal interventions, biopsies and other guiding or therapy monitoring processes utilizing the imaging of MR and OCT.
摘要:
A method is provided for a workflow for cardiovascular intervention that provides online monitoring and therapy control of the procedure. A series of steps are provided utilizing an imaging technology in combination with a therapeutic device to optimize the reliability of the treatment and minimize the negative effects on the patient. In generally, the method steps include: positioning the therapeutic device, performing the therapeutic procedure while imaging the therapeutic device, providing a low pressure inflation of the therapeutic device, imaging the results of the therapeutic procedure, and assessing the result of the therapeutic procedure. If the assessment reveals that the therapeutic procedure result is not optimal, the therapeutic procedure is performed again and the steps thereafter are performed again.
