Description

Einrichtung zur Filtersicherung und Dosismessung an Röntgengeräten Die vorliegende Erfindung ermöglicht die Dosis- und besonders die Filterkontrolle bei Röntgenapparaten in einfacherer, zuverlässigerer und auch billigeres Weise als nach den bisher bekannten Methoden.Device for filter protection and dose measurement on X-ray machines The present invention enables dose and especially filter control in the case of X-ray machines in a simpler, more reliable and also cheaper way than according to the previously known methods.

Das Wesentliche und Neuartige der Erfindung ist die feste Verbindung der strahlenempfindlichen Meßvorrichtung mit dem Strahlenfilter. Dadurch wird verhindert, daß eine Dosisumessung ohne das bei der Bestrahlung, Durchleuchtung oder Aufnahme zur Verwendung gelangende Filter vorgenommen wird. The essential and novel feature of the invention is the fixed connection the radiation-sensitive measuring device with the radiation filter. This prevents that a dose measurement without that in the case of radiation, fluoroscopy or recording used filter is made.

Als strahlenempfindliche Meßvorrichtung dient in an sich bekannter Weise eine Ionisationskammer oder eine Sperrschichtphotozelle mit oder ohne Leuchtfolie, jeweils in fester Verbindung mit dem Filter oder durch Einbau in das Filter nach besonderer Vorschrift. Es kann zu diesem Zweck entweder eine normale Photozelle an dem Filter befesügt werden, oder es wird gemäß einer weiteren Ausgestaltung der Erfindung die Filtersubstanz selbst für die Ableitung des Photostroms benutzt. Z. B. kann bei Verwendung eines Kupferfilters die lichtempfindliche Schicht unmittelbar auf dem Kupfer aufgetragen werden; dabei kann die Halbleiterschicht, in der der Photostrom bei Belichtung entsteht, in an sich bekannter Weise mit fluoreszerender Substanz beiderseits bestrichen oder homogen vermischt werden. Der durch Strahlung erzeugte Strom wird nach einem weiteren Merkmal der Erfindung z. B. mittels Spezialstecker in einem einpoligen abgeschirmten Kabel, Rückleitung durch Erde, voll der Röntgenröhre an den Schalttisch geleitet, wo er mit einem Instrument gemessen wird. Der Spezialstecker kann so eingerichtet sein, daß eine Inbetriebnahme des Röntgenapparates ohne Einschaltung des Filterstroms unmöglich ist. Damit ist eine Bestrahlung, Durchleuchtung oder Aufnahme ohne Filter und ebenso eine Bestrahlung, Durchleuchtung oder Aufnahme ohne Dosismessung ausgeschlossen. The radiation-sensitive measuring device used is a known per se An ionization chamber or a barrier photocell with or without a luminescent film, in each case in a fixed connection with the filter or by installing it in the filter special regulation. Either a normal photocell can be used for this purpose be attached to the filter, or it is according to a further embodiment of the Invention uses the filter substance itself for the dissipation of the photocurrent. Z. B. when using a copper filter, the photosensitive layer can be applied directly to be applied on the copper; the semiconductor layer in which the Photocurrent is created during exposure, in a manner known per se with fluorescent The substance can be coated on both sides or mixed homogeneously. The one from radiation generated electricity is according to a further feature of the invention, for. B. by means of a special connector in a unipolar shielded cable, return through earth, full of the x-ray tube to the indexing table, where it is measured with an instrument. The special plug can be set up so that a commissioning of the X-ray machine is impossible without switching on the filter current. So there is radiation, fluoroscopy or recording without a filter and also irradiation, fluoroscopy or recording excluded without dose measurement.
