(a) Angular dispersive measurement geometry: side view of AD-CSCT geometry (a1); each row of the detection at different w is a line integration along a section of a hyperbolic curve in q−Δl space (a2). (b) Energy dispersive measurement geometry: side view of ED-CSCT geometry (b1); the detection for each energy channel is also a line integration along a specific hyperbolic curve in q−l space (b2).
