    摘要： Disclosed are methods and systems for amplitude digitization of nuclear radiation pulses. The method includes: applying a constant fraction discrimination (CFD) timing process on a subject current signal and outputting a CFD timing signal; applying a shaping process on the subject current signal to obtain a subject shaped signal; comparing, from a time To, values taken at the same time by the subject shaped signal and a dynamic threshold signal, and taking a time Tot as an over-threshold time if the value of the dynamic threshold signal changes from less than the value of the subject shaped signal to not less than the value of the subject shaped signal at the time Tot, wherein a time length between the time To and the arrival time Td of the subject current signal is preset as ΔT; converting a time length between the time Td and the time Tot into a digital quantity as a digitized value of the amplitude of the nuclear radiation pulse; wherein for any two subject shaped signals having amplitudes Vot1 and Vot2, respectively, the dynamic threshold signal satisfies an equation Tot ⁢ ⁢ 2 - To Vot ⁢ ⁢ 2 = Tot ⁢ ⁢ 1 - To Vot ⁢ ⁢ 1 , Tot1 represents an over-threshold time for one of the subject shaped signals compared with the dynamic threshold signal, and Tot2 represents an over-threshold time for the other of the subject shaped signals compared with the dynamic threshold signal.

    摘要： The present invention provides a method for sharing a graphics card among multiple Operation Systems (OSs) and a computer system. The method comprises: detecting a first GOS to be displayed, the first GOS being one of at least two GOSs; calling a correspondence table to determine a first display control register bank corresponding to the first GOS, the first display control register bank including display mode parameters therein; controlling the first display control register bank to connect to a display output port; and displaying the first GOS based on the display mode parameters. According to the inventive method and computer system, it is possible to achieve sharing of the graphics card among the multiple OSs and quick display of the GOS to be displayed, without simulating registers of the graphics card.

    摘要： A system and method for performing magnetic resonance elastography (MRE] of a patient's breasts is provided. An MRE driver configured to be placed on the sternum of the patient is used to impart mechanical energy to the sternum, which in turn generates shear waves in at least one of the patient's breasts. Such a driver is amenable to use with standard breast radio frequency (RF] coils without the need for modification of the existing breast RF coil hardware.
