| 20100086184 | Method for Automatic Quality Control of Data in In-Vivo Images - A method for quality control assessment in single time-point in-vivo imaging data related to imaging of objects, includes acquiring an in-vivo image of the object with imaging apparatus, defining a background image corresponding to an imaged air of the in-vivo image, defining an object image corresponding to the in-vivo image from which the background image has been removed, obtaining the background and object images by atlas-based registration, reflecting an intensity distribution of the background image with a histogram, fitting a noise mathematical model to part of the histogram intensity distribution, deriving background quality characteristics from the noise mathematical model, reflecting an intensity distribution of the object image with a further histogram, fitting a signal mathematical model to the further histogram intensity distribution, deriving object quality characteristics from the signal mathematical model, and automatically deriving signal-to-noise and contrast-to-noise ratios of in-vivo imaging data from the object quality and background quality characteristics. | 04-08-2010 |
| 20090324046 | METHOD FOR SEGMENTATION OF AN MRI IMAGE OF A TISSUE IN PRESENCE OF PARTIAL VOLUME EFFECTS AND COMPUTER PROGRAM IMPLEMENTING THE METHOD - A method and computer program for segmentation of an MRI image of tissue in presence of partial volume effects, include storing the MRI image in K-space representation as raw dataset, reconstructing N images, each represented by N sets of voxels and N sets of light intensity values, dividing each voxel into a fixed number of subvoxels equal in size, assigning the light intensity value of the voxel to its subvoxels, classifying each subvoxel according to light intensity value, identifying a totality of subvoxels classified with equal probability for a totality of tissue types, labeling the subvoxels as partial volume subvoxels, shifting N−1 images starting with the second image by one subvoxel relatively to the preceding image and gene-rating a new set of overlay subvoxels, determining a new set of probability values for the new set of overlay subvoxels and creating an overlay image of the new set of overlaid subvoxels. | 12-31-2009 |
| 20080252440 | Distributed Monitoring Method - A distributed monitoring method, which can be used in a security system, a fire prevention system, transformer stations, base stations for mobile communication and places for internal management of many kinds of facilities, uses a controller and at least two field devices, and the communication between the controller and the field devices is by way of a fieldbus. A signal frame transmitted therein includes a field device address segment, a field device sub-address segment, a read/write flag segment, a data exchange segment between the controller and a field device and a reporting request by a field device to the controller. If none of the field devices detects any abnormal event, the controller performs inspection of all the field devices in turn; when one of the field devices finds an abnormal event, this field device sends a reporting request to the controller. It is possible to reduce the system's power consumption by setting a different power status for the field devices. | 10-16-2008 |
