A method of performing 4-dimensional virtual endoscopy includes acquiring a sequence of cardiac images of a patient's heart from an imaging device; acquiring an electrocardiographic signal exhibiting cardiac cycles of the heart; and utilizing the electrocardiographic signal to gate the images for deriving respective 3-dimensional views in succession at corresponding cardiac cycles, from respective cardiac images at a selected phase point common to each of the corresponding cardiac cycles.

An airbag fastening system in an airbag module has a clamping connection and includes a retaining ring for an injection orifice of the airbag in an airbag receptacle surrounding both the airbag module and the retaining ring. The retaining ring has a reducing width on an outer face in a main pulling direction when the airbag unfolds. At least a portion of the airbag receptacle or a component associated with the airbag receptacle has a smaller width above the retaining ring than a greatest width of the retaining ring. A lower end of the airbag forms the injection orifice, is folded over the retaining ring, and extends between the retaining ring and the airbag receptacle or the component. The retaining ring includes at least one portion having a conically tapered cross-section on the outer face in the main pulling direction when the airbag unfolds.

A method for aligning a pair of images includes providing a pair of images, identifying salient feature regions in both a first image and a second image, wherein each region is associated with a spatial scale, representing feature regions by a center point of each region, registering the feature points of one image with the feature points of the other image based on local intensities, ordering said feature pairs by a similarity measure, and optimizing a joint correspondence set of feature pairs by refining the center points to sub-pixel accuracy.
摘要:
A system and method for registering a sequence of inter-operative two dimensional (2D) medical images of a target feature with pre-operative three dimensional (3D) medical images of the target feature is disclosed. The 3D image of the target feature is converted to a first skeletal graph. The 2D image of the target feature is converted to a second skeletal graph. Graph matching of the first and second skeletal graphs is performed to obtain a rough alignment of the graphs, and the first and second skeletal graph registered.

A method of aligning a pair of images with a first image and a second image, wherein said images comprise a plurality of intensities corresponding to a domain of points in a D-dimensional space includes identifying feature points on both images using the same criteria, computing a feature vector for each feature point, measuring a feature dissimilarity for each pair of feature vectors, wherein a first feature vector of each pair is associated with a first feature point on the first image, and a second feature vector of each pair is associated with a second feature point on the second image. A correspondence mapping for each pair of feature points is determined using the feature dissimilarity associated with each feature point pair, and an image transformation is defined to align the second image with the first image using one or more pairs of feature points that are least dissimilar.
摘要:
A computer-implemented method is disclosed for comparing three dimensional (3D) digital medical images. The method uses a reference MPR to position subsequent MPRs in one or more other 3D digital medical images so their content matches the reference MPR. The matched MPRs may then be used by a medical professional to diagnose a patient condition. The ability to quickly and automatically position matching MPRs for multiple 3D images eases the medical staff workload and shortens diagnostics time. Matching MPRs provides an effective way to view the 3D volumes for anatomical changes over time and to monitor medical conditions such as stenosis and tumors.

A module assembly for an airbag device for protecting occupants of motor vehicles includes a carrier for the assembly, an inflatable airbag packet, a flexible protective envelope, and a fixing mechanism. The airbag packet is fixed to the carrier. The airbag packet is accommodated in the flexible protective envelope. The protective enveloped can be closed off in a gastight manner. The fixing mechanism fixes the airbag packet to the carrier. The fixing mechanism includes a holding element. The holding element, which includes a securing mechanism provided on the carrier to fix the airbag packet to the carrier, extends along an edge of the airbag packet. The securing mechanism is formed integrally on the carrier and is resiliently pivotable with respect to a lateral section of the carrier. Alternatively, the securing mechanism is fixed on the carrier as a separate assembly.
