Abstract
A radiation imaging system is disclosed. A radiation source directs a thin spread beam of radiation toward a detector assembly which is aligned with the radiation beam. The detector assembly includes a printed circuit board having a bowed configuration and bearing board circuitry. An array of photodiode detector elements are attached to the board. The detector includes a front and a rear array of elements arranged one behind the other. The circuit board defines a slot between the front and rear arrays in which a radiation filter can be removably and slidably interposed. The detector elements are buried or recessed in outer surfaces of the circuit board to a depth sufficient to position contact fingers of the elements substantially flush with the unrecessed surface of the board. Radiation sensitive phosphor material is removably positioned over each of the respective front and rear detector element arrays.
