摘要： An apparatus for determining an enhanced image of a vascular treatment provides (12) a plurality of images including a representation of a region of interest of a vascular structure. Each of the plurality of images includes image data of at least one localizing feature associated with at least one tool configured to be used in the vascular treatment. Each of the plurality of images also includes image data associated with the at least one tool. Registration information for each of the images of the plurality of images is determined (14). At least two images from the plurality of images are selected (16) as a function of the registration information for each of the images. An enhanced image that provides for enhanced visibility of the at least one tool is determined (20). Data representative of the enhanced image is output (24).

摘要： The invention relates to a protection system (10) and a method for protecting a staff member (6) against X-ray scatter radiation, an X-ray system and a computer readable medium having stored a computer program element for controlling such system. The protection system (10) comprises a location unit (20), and a determination unit (30). The location unit (20) is configured to detect the position of a shielding device (3) and the position of the staff member (6) to be protected. The determination unit (30) is configured to determine an origin (5) of potential X-ray scatter radiation and to determine if the shielding device (3) is positioned to protect the staff member (6) to be protected based on the origin (5) of potential X-ray scatter radiation, the position of the shielding device (3) and the position of the staff member (6).

摘要： A controller and a related method of controlling a collimator. The controller operates to select a collimator setting for collimator of an x-ray imager for acquiring an image of a ROI in a patient. The controller operates to select the collimator setting to optimize the patient dosage in respect of primary radiation and secondary radiation dosage of medical staff. A position detector supplies to the controller a current position of a person relative to a patient. Based on said supplied position, the controller's configured to perform an optimization procedure that takes into account the staff dosage in respect of the secondary radiation dosage to reduce the secondary radiation dosage.

摘要： A controller (CC) and a related method of controlling a collimator (COL). Controller (CC) operates to select a collimator setting for collimator (COL) of an x-ray imager (100) for acquiring an image of a ROI in a patient (PAT). The controller (CC) operates to select the collimator setting to optimize the patient dosage in respect of primary radiation (PR) and secondary radiation (SR) dosage of medical staff (MS). A position detector (PD) supplies to controller (CC) a current position of a person (MS) relative to patient (PAT). Based on said supplied position, the controller (SS)'s optimization procedure takes into account the staff (MS) dosage in respect of secondary radiation (SR) to reduce same.

摘要： An imaging system and a related method include a marker detection system (MDS) to detect one or more markers (MK) spatially arranged in association with an area (A). If the marker detection system (MDS) detects that the area (A) is within a field-of-view (FoV) of the imaging system or is at least within a predefined distance thereof, a control signal is issued in respect of the area (A) to an image acquisition system (ACS) of the imaging system. The area (A) may be one of a hand of a human operator or a part of a patient to be imaged.

摘要： The present invention relates to image contrast enhancement. In order to provide improved and stable contrast enhancement for each acquired image, a device (10) for image contrast enhancement of an X-ray image of a vascular structure is provided. The device (10) comprises an input unit (12) and a processing unit (14). The input unit is configured to provide an acquired X-ray image of a vascular structure with a contrast injection. The contrast injection is performed with a current contrast injection setting having at least one contrast injection parameter. The input unit is further configured to provide a generic vascular structure. The input unit is also configured to provide the current contrast injection setting. The processing unit is configured to determine an assessed contrast parameter for the generic vascular structure based on the current contrast injection setting. The processing unit is further configured to determine an adapted image contrast enhancement for the generic vascular structure based on the assessed contrast parameter. The processing unit is also configured to apply the adapted image contrast enhancement to the acquired X-ray image in order to generate a contrast-enhanced X-ray image.

摘要： A medical imaging system having an X-ray image acquisition device, a plurality of proximity sensors located at components of the X-ray image acquisition device and a processing unit is able to prevent unintended X-ray radiation to an object in a field of irradiation. For this purpose, the processing unit is configured for determining temporal differences of distance information delivered by the proximity sensors, for generating reference distance information based on acquired distance information with an X-ray source, an X-ray detector and the patient support in fixed positions, for filtering out reference distance information from the acquired distance information and for generating a signal in case temporal differences are determined exceeding a predetermined threshold.

摘要： An apparatus aids operation of an interventional x-ray imager during image acquisition, where the X-ray imager is configured to vary X-ray dosages depending on differences in X-ray attenuation levels across an object of interest to be imaged. The X-ray imager is further configured to assume any one of a plurality of imaging geometry positions when acquiring an image. An indication, visual, acoustic or haptic, to the operator of the X-ray imager is provided on the incurred change in X-ray dosage when changing from a current projection view to an updated projection view, while a given constant image quality is maintained throughout the different views.
