A flat panel detector that converts x-ray energy into an electrical signal and bypasses the use of a scintillator is:
CR
AEC
direct DR capture
indirect DR capture
direct DR capture
Rationale: Direct capture technology eliminates the need for a scintillator as the design of the flat panel includes a layer of selenium, allowing less diffusion of electrons which will not affect spatial resolution.
