2024年7月18日 · An x-ray tube functions as a specific energy converter, receiving electrical energy and converting it into two other forms of energy: x-radiation (1%) and heat (99%).

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 55 and 100 mm, and thickness of 7 mm, connected to the positive side of the electrical circuit.

2021年8月6日 · A focusing cup is a negatively charged, shallow depression on the surface of the cathode of an x-ray tube, which concentrates the electron beam towards the focal spot of the anode. It is typically composed of nickel.

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 exposure to X-rays and producing a more uniform image.

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 electrons for the generation of x-ray beams.

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 producing x-rays. The x-rays produced include Bremsstrahlung and the characteristic radiation for the anode element.

2024年10月21日 · Chest x-ray lines and tubes can be easily assessed and should be the first thing you look at when reviewing a chest x-ray. The assessment of their position is important, but they also give you an idea of how sick the patient is and narrow down the differential diagnosis.

2023年8月10日 · Filament current should not be confused with tube current which the latter determines the flow of electrons from the cathode to the anode. The tube voltage (kVp) and tube current (mA) is supplied by a voltage step-up transformer, where the voltage of the tube is stepped up from 220 V to 75 kV with a resulting tube current of 100 to 200 mA 1 .
