Magnification K-Edge Angiography Utilizing 100-μm-Focus Tungsten Tube and Gadolinium-Based Contrast Media

概要
- 論文の詳細を見る
A microfocus X-ray tube is useful for performing magnification digital radiography. The 100-μm-focus X-ray generator consists of a main controller, for regulating tube voltage and current, and a tube unit with a high-voltage circuit and a fixed anode X-ray tube. The maximum tube voltage, current, and electric power were 106 kV, 0.5 mA, and 50 W, respectively. Using a 100-μm-thick tungsten filter, the X-ray intensity was $19.8$ μGy/s at 1.0 m from the source with a tube voltage of 100 kV and a current of 0.50 mA. Since K$\alpha$ rays from tungsten targets are absorbed effectively by gadolinium-based contrast media, these rays are useful for performing enhanced angiography. Magnification angiography was performed by threefold magnification imaging using a computed radiography system and the filter at a tube voltage of 100 kV. In angiography of nonliving animals, we observed fine blood vessels of approximately 100 μm with high contrasts.
