    摘要: A PET scanner (20, 22, 24, 26) generates a plurality of time stamped lines of response (LORs). A motion detector (30) detects a motion state, such as motion phase or motion amplitude, of the subject during acquisition of each of the LORs. A sorting module (32) sorts the LORs by motion state and a reconstruction processor (36) reconstructs the LORs into high spatial, low temporal resolution images in the corresponding motion states. A motion estimator module (40) determines a motion transform which transforms the LORs into a common motion state. A reconstruction module (50) reconstructs the motion corrected LORs into a static image or dynamic images, a series of high temporal resolution, high spatial resolution images.

    摘要: A method of processing a positron emission tomography (PET) imaging data set (30) acquired of a subject includes independently localizing each positron-electron annihilation event of the PET imaging data set based on time of flight (TOF) localization of the positron-electron annihilation event to form a generated image (34). The generated image may be displayed. The generated image is suitably used as the basis for an initial image of an iterative reconstruction (40) of the PET imaging data set (30) to produce a reconstructed image (42). A spatial contour (56) of an image of the subject in the PET imaging data set (30) is suitably delineated based on the generated image (34). A subject attenuation map (62) for use in PET image reconstruction (40) is suitably constructed based in part on the spatial contour (56).

    摘要: A PET apparatus includes a detector array including individual detectors which receive radiation events from an imaging region. A movement controller controls at least one of relative longitudinal movement between a subject support and the detector array and circumferential movement between the detector array and the subject. A time stamp processor assigns a time stamp to each received radiation event. A list mode event storage buffer stores time stamped events. An event verification processor screens for coincidentally received radiation events, locations at which each pair of corresponding coincidentally received events defining a line of response. A reconstruction processor reconstructs valid events into an image representation of the imaging region.

    摘要: A computer implemented method for clustering customers includes receiving a source set of customer records, wherein each customer record represents one customer, and each customer record includes at least one data attribute, and each data attribute has an attribute value; pre-processing the source set of customer records to generate a pre-processed set of customer records; executing a clustering algorithm on the pre-processed set of customer records to group the pre-processed set of customer records into clusters of a pre-defined number. The pre-processing comprises: determining the type of a customer in the source set of customer records; using a type attribute value to indicate the type of the customer in its customer record; normalizing data attribute values and type attribute values; weighting to the data attribute values and the type attribute values respectively to obtain weighted attribute values of the data attribute and weighted attribute values of the tune attribute.

    摘要: A method for storing information items from a client device to a remote server is performed at the client device having memory and one or more processors, the remote server being communicatively coupled to the client device. The client device renders an information item and an information storing option associated with the information item using a first application at the client device. Upon detecting a user selection of the information storing option, the client device invokes a second application, which may or may not run on the client device, to upload data associated with the information item rendered on the client device to the remote server and then resumes the rendition of the information item using the first application at the client device.
