The present invention refers to an angiographic image acquisition system and method which can beneficially be used in the scope of minimally invasive image-guided interventions. In particular, the present invention relates to a system and method for graphically visualizing a pre-interventionally virtual 3D representation of a patient's coronary artery tree's vessel segments in a region of interest of a patient's cardiovascular system to be three-dimensionally reconstructed. Optionally, this 3D representation can then be fused with an intraoperatively acquired fluoroscopic 2D live image of an interventional tool. According to the present invention, said method comprises the steps of subjecting the image data set of the 3D representation associated with the precalculated optimal viewing angle to a 3D segmentation algorithm (S4) in order to find the contours of a target structure or lesion to be examined and interventionally treated within a region of interest and automatically adjusting (S5) a collimator wedge position and / or aperture of a shutter mechanism used for collimating an X-ray beam emitted by an X-ray source of a C-arm-based 3D rotational angiography device or rotational gantry-based CT imaging system to which the patient is exposed during an image-guided radiographic examination procedure based on data obtained as a result of said segmentation which indicate the contour and size of said target structure or lesion. The aim is to reduce the region of interest to a field of view that covers said target structure or lesion together with a user-definable portion of the surrounding vasculature.

The present invention relates to an ultrasonic diagnostic equipment 1 which projects ultrasonic signals into a patient, and which generates an ultrasonic image on the basis of reflection echoes from within the patient. The ultrasonic diagnostic equipment 1 comprises a workflow system 21 which controls equipment operations including the generation of the ultrasonic image, in accordance with a workflow protocol based on the examination procedure of steps created beforehand, and a visual workflow editor 22 which is so constructed as to edit the workflow protocol visually with icons on a screen. Owing to the configuration, the creation of the workflow protocol is facilitated, chances for the utilization of the workflow system are expanded, and even users, such as beginners, who are slightly skilled in the ultrasonic diagnostic equipment and have experienced operations little, are permitted to master the operating method of the equipment promptly and to operate the equipment more easily.

The present disclosure relates to multi-layer X-ray sources having decreased hydrogen within the layer stack and / or tungsten carbide inter-layers between the primary layers of X-ray generating and thermally-conductive materials. The resulting multi-layer target structures allow increased X-ray production, which may facilitate faster scan times for inspection or examination procedures.

A system and method for watermarking data that includes a client device, a file system manager, a file server, and a storage network. The file system manager sets watermark control information. The file server includes: (1) a file writing process including a file watermark examination procedure and an action procedure, the action procedure determining an action based on a result of the file watermark examination; and (2) a file reading process including a watermark definition procedure, a file handle / memory preparation procedure, a file data copy procedure, and a watermark insertion procedure. During a read request the watermark definition procedure determines whether a file to be read is to be watermarked based on a user at the client device that requested to read the file. Whether a write request is processed or not is based on the user and whether the file to be written contains a watermark.

In an operating method for user interface for a computed tomography examination procedure a menu and a workflow list are merged on a computer screen. One or more scanning programs can be selected in a parameter setting area on the computer screen, each scanning program corresponding to one default patient posture. When an “end of examination” option in the workflow list is selected, job status information is displayed in the parameter setting area, prompting an operator to check the status of the job selected in set reconstruction parameters. Using the interface the user can improve operational efficiency, thereby saving operational time and shortening time spent in examining each patient.

An N-M tomography system comprising: a carrier for the subject of an examination procedure; a plurality of detector heads; a carrier for the detector heads; and a detector positioning arrangement operable to position the detector heads during performance of a scan without interference or collision between adjacent detector heads to establish a variable bore size and configuration for the examination. Additionally, collimated detectors providing variable spatial resolution for SPECT imaging and which can also be used for PET imaging, whereby one set of detectors can be selectably used for either modality, or for both simultaneously.

Method for examining kidney disease, which comprises detecting fatty acid binding protein derived from kidney tissues, which is present in specimen collected from mammal excluding Rodents. By the present method, it is possible to obtain test results, which may be very important information for diagnosis or prognosis of kidney disease that has been very difficult in the past. Based on test results obtained by the present method, it may be possible to select a suitable method for treatment of kidney disease with taking into consideration risks such as the prognosis, etc. Besides, the present method can be applied to, in addition to the kidney disease samples, urine samples as well, so that the examination procedure can be simple and efficient.

The present invention relates to an apparatus and method of automating arrival and departure procedures in an airport, by which the forgery of a passport, the identity of a passport bearer, the arrival or departure permission according to a result of arrival and departure examinations, and the carry-on of prohibited items on the plane are automatically checked. The apparatus for automating arrival and departure procedures according to the present invention includes an exit gate, a departure automation apparatus, and may further include an entrance gate and a scanner. In the apparatus for automating arrival and departure procedures according to the present invention, a departure area entry procedure, a security screening procedure, and a departure examination procedure for departure passengers, which are conventionally performed separately in different areas, may be incorporated in the same area and performed therein.

To observe a catheter (43) advancing in a vessel system, a 3D model of the vessel system is reconstructed with the help of differently oriented X-ray projections (P1A, . . . ) generated by a C-arm system (20) during the injection of a contrast agent. Next, a movement corridor (M) of the catheter (43) is determined from the 3D model. During an examination procedure, current projections (P) are generated showing an image (43′) of the catheter that can be registered with the reconstructed 3D model and / or the movement corridor (M). Based on the registered catheter image and 3D model of the vessel geometry or the movement corridor (M), an optimal projection direction (dopt) is determined and the C-arm system (20) is controlled to orient the next projections in the optimal projection direction.

The invention relates to an examination couch, in particular to an interesting pediatric examination couch which comprises a base and the like. A mounting mechanism is connected with the top of the base, and a swing mechanism is arranged in the base. The interesting pediatric examination couch has the advantages that children can be conveniently examined by the aid of the interesting pediatric examination couch, and examination tools can be conveniently fetched by the aid of the interesting pediatric examination couch; the mounting mechanism can bring convenience for arranging the children, the children can be continuously slowly shaken by the swing mechanism, moods of the children can be pacified, and accordingly the children can be conveniently examined; attention of the children can be attracted by cavities, and accordingly the children can be conveniently examined; the interesting pediatric examination couch is provided with a placing table, the placing table is favorable for conveniently fetching and placing the examination tools for examining the children, the hands and the feet of the children can be bound by binding bands, and the children can be prevented from struggling in examination procedures.
