Title:
X-RAY CONTROL DEVICE
Document Type and Number:
Japanese Patent JP2586262
Kind Code:
B2
Abstract:
PURPOSE: To provide low power consumption by previously storing setting tube current-time product value allowing setting and by generating an X-ray interrupting signal with the aid of a means when the time reaches a setting time value.
CONSTITUTION: A setting tube voltage value signal KV and a setting tube current-time product value signal mAs are stored in one ROM and the other ROM respectively to determine whether an inputted address signal is in a rated range or not. The signals from the ROMs are latched in a latch circuit and are sent to setting tube voltage display circuit 60 and a setting tube current-time produce display circuit 70 and are displayed in decimal number. And, the setting KV signal is also sent to a D/A conversion circuit 51 in an X-ray tube voltage control circuit to generate a tube voltage according to a set value. In addition, the setting mAs signal is sent to a tube current-time product timer circuit 80. A timer circuit 32 starts counting in accordance with X-ray exposure. When the count value reaches a count value outputted from a conversion circuit 81, an X-ray interrupting signal is generated. Thus, the control of the setting KV and the mAs value is facilitated to provide lower power consumption.
