X-RAY FIELD DEFINING MASK |
摘要 |
In a spot film device, a cassette assembly for a film cassette is mounted for reciprocating in a tunnel between an X-ray exposure position and a position in which the cassette is automatically unloaded or loaded with film. Field defining masks are also mounted for translating selectively with the carriage. The masks are formed of the synthetic materials having minimal X-ray absorption and high rigidity, without an aperture, to define a sharp X-ray field. |
