Boyd, D P

This patent describes, for use in X-ray computed tomography, a position-sensitive detector for detecting continuous divergent rays of penetrating radiation transmitted from an X-ray point source of penetrating radiation through an object to be imaged, the detector comprising: a detector housing; anode and cathode electrode means spaced apart to define a gap therebetween within the housing; and at least one of the spaced apart anode or cathode electrode means including a divergent array of spaced apart elongated electrically conductive electrodes defining a divergent array of elongated detector gaps therebetween, with the electrodes being parallel to radiation emitted by the X-ray point source of penetrating radiation; and separate signal detection means each individually connected to a respective one of the electrodes for simultaneously detecting a signal from each of the electrodes.
