Abstract: A CT detector includes a pixel having a single photodiode and multiple charge storage devices that are alternately stored and read out. The photodiode is a frontlit diode with a pair of capacitors that alternately store charge generated during data acquisition. Multiple pixels are connected to a single readout amplifier.

As such, each charge storage device is read out independently, but the charge storage devices are connected to a common readout channel or port.

Abstract: A technique for selectively attenuating a radiation exposure in which a configurable collimator is employed between the radiation source and the radiation target. The configurable collimator typically comprises an array of independently addressable elements each of which has at least a high and a low attenuation state, though intermediate states may also be accommodated. The elements of the array may be selectively addressed to determine their state and to determine the attenuation profile of the collimator. One embodiment of the technique employs an array of microactuated attenuating louvers which may be selectively actuated to determine their radiation transmittance. A second embodiment of the technique employs a suspension of attenuating nematic colloids which may be ordered by the application of an electric or magnetic field. The ordered state of the nematic colloids within an element determine the radiation transmittance of that element.
