The new type x-ray image intensifier consists of the x-ray photocathode, a MCP and a phosphor screen, forming a proximity focus type photoelectric imaging device. A new portable x-ray diagnosis unit has the new type x-ray image intensifier and a new type compact x-ray source that has a very small volume, 30-90 kv acceleration voltage and a cone protective cover at the outlet of x-ray. |
