20080208578 | Robust Speaker-Dependent Speech Recognition System - The present invention provides a method of incorporating speaker-dependent expressions into a speaker-independent speech recognition system providing training data for a plurality of environmental conditions and for a plurality of speakers. The speakerdependent expression is transformed in a sequence of feature vectors and a mixture density of the set of speaker-independent training data is determined that has a minimum distance to the generated sequence of feature vectors. The determined mixture density is then assigned to a Hidden-Markov-Model (HMM) state of the speaker-dependent expression. Therefore, speaker-dependent training data and references no longer have to be explicitly stored in the speech recognition system. Moreover, by representing a speaker-dependent expression by speaker-independent training data, an environmental adaptation is inherently provided. Additionally, the invention provides generation of artificial feature vectors on the basis of the speaker-dependent expression providing a substantial improvement for the robustness of the speech recognition system with respect to varying environmental conditions. | 08-28-2008 |

20100309199 | PATH PROXIMITY RENDERING - The invention relates to a system (100) for visualizing an object of interest comprised in a volume of an image dataset, the system comprising a path unit (110) for specifying a path in the volume of the image dataset on the basis of the object of interest, a location unit (120) for determining a location on a projection ray through the volume of the image dataset on the basis of the specified path, and a value unit (130) for computing a projected gray value corresponding to the projection ray on the basis of the determined location on the projection ray. Because the locations on the projection ray are determined based on the specified path for indicating the object of interest, the actual computation of the projection gray values may be designed and constructed to show gray values describing the object of interest while hiding gray values describing other objects, in particular occluding objects. Thus, the system of the invention is arranged for visualizing the object of interest at different viewing angles without occluding the object of interest. | 12-09-2010 |

20120066241 | RETRIEVING AND VIEWING MEDICAL IMAGES - As medical imaging becomes more affordable, and the diversity of diagnostic modalities and therapeutic treatments increase, the amount of data being stored increases, and the problem becomes even more critical. One approach to improve retrieval efficiency of images is to employ semantics to establish a defined set of search and classification terms. However, such semantic systems still require the user to make a selection of the most appropriate term or terms to classify a report or image, and the accuracy of the results are thus dependent on the skill and knowledge of the classifier. According to a first aspect of the invention, a retriever is provided for retrieving a medical image having a searchable attribute, the retriever being configured to interface with a semantic database and an image database, and wherein the searchable attribute is determined by segmenting the medical image, using the anatomical model. | 03-15-2012 |
20120099702 | CORRECTION METHOD FOR DIFFERENTIAL PHASE CONTRAST IMAGING - The present invention generally refers to a correction method for grating-based X-ray differential phase contrast imaging (DPCI) as well as to an apparatus which can advantageously be applied in X-ray radiography and tomography for hard X-ray DPCI of a sample object or an anatomical region of interest to be scanned. More precisely, the proposed invention provides a suitable approach that helps to enhance the image quality of an acquired X-ray image which is affected by phase wrapping, e.g. in the resulting Moiré interference pattern of an emitted X-ray beam in the detector plane of a Talbot-Lau type interferometer after diffracting said X-ray beam at a phase-shifting beam splitter grating. This problem, which is further aggravated by noise in the obtained DPCI images, occurs if the phase between two adjacent pixels in the detected X-ray image varies by more than π radians and is effected by a line integration over the object's local phase gradient, which induces a phase offset error of π radians that leads to prominent line artifacts parallel to the direction of said line integration. | 04-26-2012 |

20120243658 | PHASE CONTRAST IMAGING - X-ray devices for Phase Contrast Imaging (PCI) are often built up with the help of gratings. For large field-of-views (FOV), production cost and complexity of these gratings could increase significantly as they need to have a focused geometry. Instead of a pure PCI with a large FOV, this invention suggests to combine a traditional absorption X-ray-imaging system with large-FOV with an insertable low-cost PCI system with small-FOV, The invention supports the user to direct the PCI system with reduced FOV to a region that he regards as most interesting for performing a PCI scan thus eliminating X-ray dose exposure for scanning regions not interesting for a radiologist. The PCI scan may be generated on the basis of local tomography. | 09-27-2012 |
20120250823 | CALIBRATION OF DIFFERENTIAL PHASE-CONTRAST IMAGING SYSTEMS - The present invention relates to an X-ray imaging system and a method for differential phase—contrast imaging of an object. To improve calibration of differential phase—contrast imaging systems and the alignment of the gratings an X-ray imaging system is provided that comprises an X-ray emitting arrangement providing at least partially coherent X-ray radiation and an X-ray detection arrangement comprising a phase-shift diffraction grating, a phase analyzer grating, and an X-ray image detector, all arranged along an optical axis. For stepping, the gratings and/or the X-ray emitting arrangement are provided with at least two actuators arranged opposite to each other with reference to the optical axis. For calibration, calibration projections are acquired without an object, wherein, the emitted X-ray radiation or one of the gratings is stepwise displaced with a calibration displacement value. For examination, measurement projections are acquired with an object, wherein the emitted X-ray radiation or one of the gratings is stepwise displaced with a measurement, a calibration projection is associated to each of the measurement projections by registering the latter with the calibration projections. | 10-04-2012 |
20120307966 | APPARATUS FOR PHASE-CONTRAST IMAGING COMPRISING A DISPLACEABLE X-RAY DETECTOR ELEMENT AND METHOD - The present invention relates to X-ray image acquisition technology in general. Employing phase-contrast imaging for X-ray image acquisition may significantly enhance the quality and information content of images acquired. However, phase-contrast information may only be obtainable in a small detector region, possibly being too small for a sufficient field of rotation view for specialized X-ray imaging applications. Accordingly, an apparatus for phase-contrast imaging is provided that may allow the acquisition of an enlarged field of view. According to the present invention an apparatus ( | 12-06-2012 |
