Heavy duty -500 kHU TOTANODE- X-ray systems are useful for stereo angiography with an increase in the magnification Each X-ray tube has a 125mm diameter heavy duty target disc, metal envelope, high emissivity cathode, and a high-speed revolving mechanism (10,800rpm). DRX-W625HD-SA has twin 0.2 mm foci (11 kW) and 1.2 mm focus (100kW). Twin foci can be instantaneously switched alternately by an electronic control unit using switching tubes. This X-ray tube is suitable for magnification stereo angiography and also suits for general and magnification angiography. DRX-W135HD-SA has twin 1.0 mm foci (80kW) and 0.2 mm focus (11 kW). It is suitable for contact stereo angiography. DRX-5526HD-SA and DRX-5546HD-SA have a high power variable size focuses (0.2-0.1 mm) and large focuses. DRX-5536HD has 0.2 mm focus and 1.0 mm focus. They are suit able for general and magnification angiography. The components were also designed to accomplish the above purposes. For example, the new stereo collimator has four shield wings which move independently and changes two light field synchronized with a change fin the focuces.
