摘要： The present invention relates to a method for imaging using an image-generating, endoluminal instrument (1) by means of which a sequence of 2D image data of a hollow channel (2), in particular a vessel, of an object under investigation is recorded, wherein the images are recorded in a known temporal relation to a periodic movement of the object under investigation and spatial coordinates of the image are captured by means of a position sensor during each recording of an image (5) and stored as position data (9, 10) together with the 2D image data of the image (5). The method is characterized in that first position data (10) which does not lie in a predefinable movement phase of the object under investigation is corrected, before or after being stored, by interpolation between second position data (9) which does lie in the specified movement phase and/or by subtraction or addition of predetermined values. By means of the method a movement correction of the data can be performed without the need to reduce the volume of recorded image material.

摘要： The device according to the invention ensures accurate and in particular sensitive navigation of the probe, which can be inserted into a body, despite the fact that the remote control uses simple means, by means of a movement (MR;MB;MP) corresponding intuitively to the navigation of a probe using the control device (1). Intuitive operation can be converted in particular using an inventive U-shaped embodiment of the control device (1). Sensitive controllability can be increased by transmitting the mechanical interaction between the probe and an environment under examination to the control device (1) and thus directly to the operating hand (3) by means of inventive feedback.

摘要： The present invention relates to a method and also an imaging system to compensate for patient motion when recording a series of images in medical imaging, in which a number of images of an area under examination of a patient (17) are recorded at intervals with an imaging system (1) and are related to one another. With the method a localization system (2) is used as the series of images are being recorded to permanently or at a time close to the recording of the individual images, record a momentary spatial location of the area under examination in a reference system permanently linked to the imaging system (1), a first spatial location of the area under examination recorded close to the time of recording of a first image is stored, and a deviation of the images recorded momentarily in each case of the first spatial location is determined and by changing the geometrical circumstances of the imaging system (1) at a time to close the recording of the spatial location and/or through geometrical adaptation of an image content of an image just recorded, is at least approximately commentated for, so that the images show the area under examination in the same position and orientation. The method does not require any time-consuming interaction with the operator and is also suitable for compensating for larger movements of the patient.

摘要： A method and system for autoregressive model based pigtail catheter motion prediction in a fluoroscopic image sequence is disclosed. Parameters of an autoregressive model are estimated based on observed pigtail catheter tip positions in a plurality of previous frames of a fluoroscopic image sequence. A pigtail catheter tip position in a current frame of the fluoroscopic image sequence is predicted using the fitted autoregressive model. The predicted pigtail catheter tip position can be used to constrain pigtail catheter tip detection in the current frame. The predicted pigtail catheter tip position may also be used to predict abnormal motion in the fluoroscopic image sequence.

摘要： A method and system for fusion of multi-modal volumetric images is disclosed. A first image acquired using a first imaging modality is received. A second image acquired using a second imaging modality is received. A model and of a target anatomical structure and a transformation are jointly estimated from the first and second images. The model represents a model of the target anatomical structure in the first image and the transformation projects a model of the target anatomical structure in the second image to the model in the first image. The first and second images can be fused based on estimated transformation.

摘要： A method and system for estimating 3D cardiac motion from a single C-arm angiography scan is disclosed. An initial 3D volume is reconstructed from a plurality of 2D projection images acquired in a single C-arm scan. A static mesh is extracted by segmenting an object in the initial 3D volume. The static mesh is projected to each of the 2D projection images. A cardiac phase is determined for each of the 2D projection images. A deformed mesh is generated for each of a plurality of cardiac phases based on a 2D contour of the object and the projected mesh in each of the 2D projection images of that cardiac phase.

摘要： A method for reconstruction of an actual three-dimensional image dataset of an object during a monitoring process is proposed. Two-dimensional X-ray projection images which correspond to a recording geometry are continuously recorded from different projection angles. The three-dimensional image dataset are reconstructed from a first number of these projection images, especially by a back projection method. The proportion of the oldest projection image contained in the current three-dimensional image dataset is removed from the three-dimensional image dataset and the proportion of the actual projection image is inserted in the three-dimensional image dataset after each recording of the actual projection image.

摘要： A method and system for adaptive discriminant learning and measurement fusion for image based catheter tracking is disclosed. An adaptive discriminant model is trained online based on a tracked object, such as a pigtail catheter tip, in at least one previous frame of a fluoroscopic image sequence. The object is tracked in the current frame of the fluoroscopic image sequence based at least on the adaptive discriminant model trained online. The object may be tracked in the current frame based on a fusion of three types of measurement models including the adaptive discriminant model trained online, an object detection model trained offline, and an online appearance model.
