Abstract

Eine Vorrichtung zur mehrdimensionalen, bildmäßigen Darstellung der Intensitätsverteilung einer Strahlung ent­ hält eine unter Überdruck eines Gases stehende Detektor­ kammer, die als Driftkammer mit zumindest parallelen Elektroden und ringförmigen Hilfselektroden und als der Driftkammer nachgeordnete Vieldrahtkammer mit in einer Ebene kreuzungsfrei gespannten Drähten ausgebildet ist. Mit dieser Vorrichtung sollen die auf dem Gebiet der medi­ zinischen Technik zu stellenden Forderungen wie hohes Auflösungsvermögen und geringe Bestrahlungszeiten zu erfüllen sein. Die Erfindung sieht hierzu vor, daß bei der Vorrichtung für eine zweidimensionale Darstellung die Ein­ fallsrichtung der in die Detektorkammer (2) eintretenden Strahlung (7) zumindest annähernd parallel zur Ebene der als Kollektordrähte dienenden Drähte (16) der Vieldraht­ kammer verläuft, daß diese Drähte zumindest annähernd parallel bezüglich der Einfallsrichtung der Strahlung (7) ausgerichtet sind und daß die zu registrierenden elektrisch geladenen Teilchen (18) positive Ionen des Gases sind. A device for multi-dimensional, pictorial Representation of the intensity distribution of a radiation ent holds a detector under excess pressure of a gas chamber serving as a drift chamber with at least parallel Electrodes and annular auxiliary electrodes and as the Drift chamber downstream multi-wire chamber with in one Level cross-tensioned wires is formed. With this device, those in the field of medi technical requirements such as high Resolving power and short exposure times to be fulfilled. The invention provides for this that Device for a two-dimensional representation the one If the direction of the entering into the detector chamber (2) Radiation (7) at least approximately parallel to the plane of the serving as collector wires (16) the multi-wire chamber runs that these wires at least approximately parallel to the direction of incidence of the radiation (7) are aligned and that the to be registered electrically charged particles (18) are positive ions of the gas.
