G-1077/G-1078 ®

Product catalog summary
Product Description: The G-1077 is a rotating anode X-ray tube with a 4.25-inch diameter, designed for radiographic procedures such as cineradiography and angiography. It can handle up to 150 kV and 740 kJ of anode heat content. The tube features a 7° rhenium-tungsten facing on molybdenum with a graphite-backed target, offering nominal focal spots of 0.6 - 1.0 as per IEC 60336 standards. The nominal anode input power is 48 kW for small focal spots and 90 kW for large focal spots, with an equivalent anode input power of 235 Watts. The G-1078 model includes grid control capability.
Specifications: The tube is intended for use in B-160H housings. Grid control voltages are specified as -3700Vdc for cutoff at 150 kV and 0 Vdc for exposure. The design supports a perpendicular reference axis to the port face.
Emission and Load Ratings: Detailed charts for filament emission and single load ratings under various conditions (50 Hz, 60 Hz, 150 Hz, 180 Hz) are included, as per IEC 60613 standards. These charts help determine the maximum allowable kW for cine pulses and the maximum time for cine runs based on duty factor calculations.
Cineradiographic and Angiographic Ratings: Cineradiographic charts determine the maximum allowable kW for cine pulses, considering factors like pulse width, exposures per second, and cine run time. Angiographic charts guide managing the high demands of serial radiography, ensuring the anode does not exceed 100% heat storage to prevent damage.
Usage Instructions: Instructions are provided for using the cineradiographic and angiographic charts, including calculating duty factors and determining kW ratings for exposures. It emphasizes not exceeding 100% anode heat storage to avoid anode track erosion and potential tube destruction.
Specifications: The document outlines the calculation of exposure power in kilowatts (kW) by multiplying milliamperes (mA) by kilovolts (kV). Exposures less than 0.010 seconds have the same kW rating as those of 0.010 seconds.
Standards and Norms: The nominal anode input power is specified for an anode heat content of 70%, in accordance with IEC 60613 standards, including serial load ratings and thermal anode reference power.
Focal Spot Specifications: Details on focal spot dimensions include 0.6 and 1.0 focal spots with specifications of 3Ø, 7 degrees, and frequencies of 50/60 Hz and 150/180 Hz.
Additional Notes: Multiple language notes reiterate the calculation of exposure power and the equivalence of kW ratings for exposures under 0.010 seconds.
Anode Heating & Cooling: An anode heating and cooling chart indicates the time in minutes for these processes.
Manufacturer Information: The document is produced by Varex Imaging Corporation, with a note that specifications are subject to change without notice.
