2024年6月10日 · The anode (or anticathode) is the component of the x-ray tube where x-rays are produced. It is a piece of metal, shaped in the form of a bevelled disk with a diameter between …

2024年7月18日 · The x-ray tube contains two principal elements: filament (also acts as cathode): boils off electrons by thermionic emission. target (also acts as anode): electrons strike to …

2021年8月6日 · The anode angle refers to the angle the target surface of the anode sits at in relation to the vertical. Most x-ray tubes have an anode angle of 12-15 degrees but greater or …

2024年6月27日 · The cathode is part of an x-ray tube and serves to expel the electrons from the circuit and focus them in a beam on the focal spot of the anode. It is a controlled source of …

2023年8月11日 · Typical x-ray tube ratings are between 5-100kW and are dependent on focal spot size 2. The larger the focal spot size, the higher the ability of the anode to withstand heat …

2024年3月26日 · Anode heel effect can benefit in X-ray imaging by aligning the anode-cathode axis parallel to thinner-thicker sections of the patient's body, thereby equalising the patient's …

2024年7月2日 · X-rays are produced due to sudden deceleration of fast-moving electrons when they collide and interact with the target anode. In this process of deceleration, more than 99% …

2024年7月2日 · anode materials: different anode materials such as tungsten, molybdenum, and rhodium produces different x-ray spectra 3. anode roughness: over an operational lifetime of …

2024年7月9日 · They are produced by an x-ray tube, using a high voltage to accelerate the electrons produced by its cathode. The produced electrons interact with the anode , thus …

2024年7月5日 · tungsten is used as the metal in the filament (or cathode) in x-ray tubes due to its very high melting point 4 due to properties of high melting point, high atomic number, and low …
