  • Patent number: 9398895
    Abstract: The present invention discloses a method, apparatus and system for enhancing needle visualization in ultrasound imaging, said method comprising: a setting step for setting a scanning depth corresponding to a depth of a part or tissue target in a patient's body; and a determining step for automatically determining a needle frame steering angle and an ultrasound working frequency for needle frame collection based on the scanning depth. In the embodiments of the present invention, the needle frame steering angle and ultrasound working frequency for needle frame collection and the filter kernel for enhancing edge filtering of the collected needle frame are both dependent upon the scanning depth, and thereby can achieve enhancing needle visualization in ultrasound imaging for scanning at different depths without participation of the user or extra change of hardware.

  • Publication number: 20160053275
    Abstract: This disclosure provides plants having desirable levels of lignin synthesis, sugar release, S/G ratio, and resistance to stress and pathogens; methods of selecting plants with such desirable levels of lignin synthesis, sugar release, S/G ratio, and resistance to stress and pathogens; methods of genetically modifying plants to modulate lignin synthesis, sugar release, S/G ratio, and resistance to stress and pathogens; and uses of such plants. The inventors have determined that the expression and/or activity of POPTR_0014s08530, a gene encoding an Angustifolia/CtBP transcription factor, modulates lignin synthesis, sugar release, S/G ratio, and resistance to stress and pathogens in plants. Plants with lignin synthesis, sugar release, S/G ratio, and resistance to stress and pathogens, based on modulation of the expression or activity of the POPTR_0014s08530 gene, have divergent uses including pulp and paper production, and ethanol/biofuel production.

  • Publication number: 20150108328
    Abstract: A compensating current is applied at one or more points in a signal processing path to compensate for one or both of a dark or offset current present in an input signal. In certain implementations, the dark or offset current is present in a signal generated by a photomultiplier device. The dark or offset current may be monitored in an output of the signal processing path and, the monitoring being used to determine how much compensation is needed in the signal processing path and to allocate where in the signal processing path the compensation current will be applied.
