Definitions

  • the present invention relates to a system for controlling an X-ray generator by a computer.
  • the computer will send a voltage (5 or 12 Volts) to a relay for a predetermined time via software.
  • This relay will close during the time of reception of the current which causes the supply of 220 Volts to the generator and therefore the emission of X-rays.
  • the software which is not part of this patent makes it possible to select zones to be radiographed on diagrams on the screen and to send a voltage (5 or 12 Volts) to the relay for a predetermined time via a computer output (input-output card, home automation card, or more simply serial, parallel output, etc.).
  • This system is mainly intended for healthcare and research professionals who use ionizing radiation generators (radiologists, dental surgeons, etc.). Its use can be extended to control any electrical device.

Abstract

A system for computer-controlling X-ray generators, consisting of a relay which is activated for a predetermined time by the software of a computer. The computer supplies a voltage (5 or 12 volts) to close the relay and turn on the X-ray generator. The system may be used to control any electrical apparatus.

Description

Système de pilotage de générateurs de Rayons X par ordinateur.Control system of X-ray generators by computer.
La présente invention porte sur un système permettant de piloter un générateur de rayon X par un ordinateur.The present invention relates to a system for controlling an X-ray generator by a computer.
Jusqu'à ce jour, les générateurs de rayons X utilisés en médecine étaient commandés par de simples minuteries plus ou moins précises (1/10 secondes).Until today, X-ray generators used in medicine were controlled by simple timers more or less precise (1/10 seconds).
L'utilisation de plus en plus répandue de capteurs numériques de radiographie demande des réglages de temps d'exposition très fin (1/100 secondes). La généralisation de l'utilisation d'ordinateur par le milieu médical permet par logiciel d'activer le système ci-dessous décrit :The increasingly widespread use of digital radiography sensors requires very fine exposure time settings (1/100 seconds). The widespread use of computers by the medical community allows software to activate the system described below:
L ordinateur va envoyer pendant un temps prédéterminé par logiciel une tension (5 ou 12 Volts) sur un relais. Ce relais va se fermer pendant le temps de réception du courant ce qui provoque l'alimentation en 220 Volts du générateur et donc l'émission de rayons X.The computer will send a voltage (5 or 12 Volts) to a relay for a predetermined time via software. This relay will close during the time of reception of the current which causes the supply of 220 Volts to the generator and therefore the emission of X-rays.
Le logiciel qui ne fait pas partie de ce brevet permet de sélectionner des zones à radiographier sur des schémas à l'écran et d'envoyer sur le relais une tension (5 ou 12 Volts) pendant un temps prédéterminé via une sortie de l'ordinateur (carte entrée-sortie, carte domotique, ou plus simplement sortie série, parallèle, ...).The software which is not part of this patent makes it possible to select zones to be radiographed on diagrams on the screen and to send a voltage (5 or 12 Volts) to the relay for a predetermined time via a computer output (input-output card, home automation card, or more simply serial, parallel output, etc.).
Ce système est destiné principalement aux professionnels de santé ou de recherche qui utilisent des générateurs de radiations ionisantes (radiologues, chirurgiens dentistes,...). Son utilisation peut être étendue au pilotage de tout appareil électrique. This system is mainly intended for healthcare and research professionals who use ionizing radiation generators (radiologists, dental surgeons, etc.). Its use can be extended to control any electrical device.
