Abstract: X-ray imaging systems are provided that include an X-ray source and an X-ray detector. A filtering device is positioned between the X-ray source and the X-ray detector and includes one or more micro-filters each adapted to transition between an X-ray filtering position and an X-ray non-filtering position. A controller is programmed to control operation of the micro-filters.

Abstract: Approaches for assessing hemodynamic characteristics for an organ of interest are related. In one implementation, a fluid dynamics model may be provided with data derived from an anatomic imaging modality and blood flow information derived by ultrasound to derive the desired hemodynamic characteristics. In one such implementation, a fractional flow reserve is estimated.
