Results indicate that helical CT angiography can be used as the initial method for evaluation in patients with possible arterial injuries of the neck.

Abstract-We present two families of optical processor arrays. One family uses a pair of complex conjugate phase arrays for implementing a varifocal lenslet array, which is useful for axial scanning. The other family uses a different pair of complex conjugate phase arrays for controlling the depth of field in a telecentric processor array.
