One method includes identifying a logical graph from business network linked graph data to be transformed into a resource graph, the logical graph including at least two nodes and at least one edge connecting a pair of nodes and defining a connection between the nodes. Each node is converted into a resource.

    摘要: The application describes an X-ray detector, which uses direct X-ray conversion (DiCo) combined with CMOS pixel circuits. DiCo materials have to be used with high voltage to achieve a high field strength. This makes the sensor prone to leakage currents, which falsify the measured charge result. Moreover, most direct conversion materials suffer from large residual signals that lead to temporal artifacts (ghost images) in an X-ray image sequence. A circuit is described, which senses the sensor's dark current including residual signals from previous exposures before the sensor is exposed (again) to X-ray, and freezes relevant circuit parameters at the end of the sensing phase in such way, that the dark current (leakage current and residual signal) can still be drained during exposure. Therefore, the charge pulses generated in the sensor due to X-ray exposure can be integrated without charges carried by the leakage current or residual signal, thus obtaining a more accurate estimate of the deposited X-ray energy.
