Abstract:
A generation of sectional images of tissue is provided. In this arrangement a first light-conducting fiber of a device for generating sectional tissue images according to the optical coherence tomography principle, which light-conducting fiber is rotatably accommodated within a catheter tube, is additionally connected to a device for generating light in a further wavelength range and for detecting fluorescent light. With its use sectional tissue images produced according to the optical coherence tomography principle can be superimposed with fluorescent images.
Abstract:
The invention relates to an implant, a method and a device for determining the position of the implant. To improve the accuracy of determining the position it is proposed to provide a transponder on the implant suitable for determining the position.
Abstract:
A method is provided for quickly and simply generating a three-dimensional tomographic x-ray imaging. Tomosynthetic projection images are recorded from different recording angles along a tomosynthetic scanning path and three-dimensional image data is reconstructed from the tomosynthetic projection images. The tomosynthetic projection images are recorded by a tomosynthetic x-ray device with a plurality of x-ray sources arranged on a holder at a distance from one another. Each projection image is recorded by a different x-ray source being fixed in one place during recording the tomosynthetic projection images.
Abstract:
An imaging apparatus having a ring-shaped gantry is provided. The gantry has a rotor arrangement rotating therein and a radiation source as well as at least one radiation detector. The gantry has at least one gantry segment which can be detached from the ring shape to allow the gantry to be opened laterally. The gantry is arranged on a supporting structure so as to be movable in space. The supporting structure is a ceiling-mounted stand having at least two degrees of freedom of movement. The gantry has at least two radiation sources disposed offset by an angle on the rotor arrangement and associated with each of which is at least one radiation detector.
Abstract:
The invention relates to a method for monitoring the movement of at least one mobile object with a medical installation. A current three-dimensional position of the at least one mobile object is detected by at least one position sensor that is arranged on the at least one mobile object. The invention also relates to the associated medical installation.
Abstract:
A medical cushion is provided. The medical cushion has at least one x-ray positive and at least one electromagnetic marker and a soft filler material that yields to the force exerted by the weight of a patient and molds itself at least to some extent to the surface of the body of the patient is provided. The soft filler material is arranged in the cushion in such a manner that it lies between the surface of the body of the patient and at least one x-ray positive and at least one electromagnetic marker when the cushion is in use.
Abstract:
The invention relates to an user interface comprising: a read only memory for an operating parameter of an X-ray system with each one section for contrast medium injection, for data acquisition, for reconstruction of data, for image storage and for displaying of an image; a write-read-memory for the operating parameter which has to be transferred to the corresponding section of the X-ray system; and a control unit for copying the operating parameter from the read only memory into the write-read-memory. The copied operating parameter is graphically supported within the write-read-memory alterable.
Abstract:
Guidewire for catheters which can be inserted into cavities, preferably coronary vessels of humans or animals, said guidewire being provided with electromagnetic receive or transmit locate to position its position in conjunction with corresponding external electromagnetic transmit or receive antennas, as well as with signal lines guiding the processing unit controlling the transmit antennas or transmit coils.
Abstract:
A method for image support in the navigation of a medical instrument for a minimally-invasive intervention for therapy of a tumor in human body is proposed. A first current three-dimensional image dataset is recorded shortly before the intervention with an x-ray device showing the tumor. A second current three-dimensional image dataset is recorded with the x-ray device highlighting the blood vessels in the vicinity of the tumor while providing a contrast medium. The first and the second current image dataset are merged into a first merged image dataset. Two-dimensional images showing the medical instrument are repeatedly imaged with the x-ray device and/or an ultrasound device and/or determination of position data reflecting the three-dimensional position of the instrument by a position determination device registered with the x-ray device. The first merged image dataset is merged with the two-dimensional images and/or the position data to form a second merged image dataset.
Abstract:
A system and method for treating a patient using a hybrid imaging system is provided. For example, first imaging data is acquired from a patient using a first imaging device. The patient is transferred on a support to a second imaging device. The support extends between the first imaging device and the second imaging device. Second imaging data is acquired from the patient using the second imaging device. The second imaging device structurally allows for catheter treatment in the patient during acquisition of the second imaging data. The first imaging data and the second imaging data are superimposed or fused. The patient is treated with a catheter as a function of the superimposed or fused data while acquiring the second imaging data.
