Abstract

PURPOSE:To display a set value and an actual tube electric current by only a single display unit, by switching each output of an integrator integrating an actual tube current during the period of an image pickup to that of a multiplier generating a voltage proportional to a predetermined tube current and vice versa. CONSTITUTION:Before an X-ray photographing is carried out, a predetermined tube electric current signal 1 and a predetermined time signal 2 required for photographing are fed into a multiplier 3 and an output voltage proportional to a predetermined tube electric current capacity is obtained and displayed on a display unit 15 through a contact 8 and a logarithmic converter 13. Next, the contact 8 becomes open by a starting signal 4 for photography and contacts 9 and 10 are closed by a positive electrode starting signal 9. A tube electric current of an X-ray tube 19 is integrated by a integrator 12 and displayed on the display unit 15 through the contact 9 and the logarithmic converter 13. Consequently it can be achieved to display the predetermined tube electric current capacity and an integrated value of an actual tube electric current. By comparing these, it is also possible to always keep an X-ray device in good conditions.
