Easily-produced lightweight X=ray image chamber - comprises pressurised ionisation chamber with special bracing and binding

摘要

Ionisation chamber is constructed to withstand high internal pressure with the mechanical support of an outer chamber whose walls (excluding the X-ray window comprise a shaft metal layer, (pref. of ribbed al), covered by a flexible layer. The latter may form part of a complete binding of the equipment made from low X-ray absorbing material of high modulus and may be part - parabolically shaped to resist internal pressure. Lightweight low X-ray interaction packing, e.g. Acrylic foam, may be used between the chamber and the binding walls and between the metal ribs of the stiff layer mentioned. The lightweight construction facilitates pivoting so that easy manoeuvring around a patient is obtd.
