How are photons created in the xray tube
WebLower energy x-rays, called orthovoltage X-rays, are used to treat cancers closer to the surface. [3] Megavoltage x-rays are preferred for treatment of deep lying tumours as they are attenuated less than lower energy photons, and will penetrate further, with a lower skin dose. [4] [5] [6] Megavoltage x-rays also have lower relative biological ...

WebThe energy of an x-ray beam may be described by identifying the peak operating voltage (in kVp). A dental x-ray machine operating at a peak voltage of 70,000 volts (70 kVp) for … WebX-radiation is created by taking energy from electrons and converting it into photons with appropriate energies. This energy conversion takes place within the x-ray tube. The quantity (exposure) and quality (spectrum) of …
WebIt must be stressed that Fig. 24 only indicates the types of interaction, and does not represent the direction of emission of the photons or how often they occur, both of which features of the X-ray production process depend upon the energy of the electrons—i.e., upon the applied voltage—as will be described later.

In this inefficient process, 1% of the electrons’ energy is converted to x-rays and 99% to heat (or waste). The photons (x-rays ...
WebAs the energy (which is proportional to the peak voltage) of the stream of electrons in the X-ray tube increases, the X-ray photons created from those electrons are more likely to penetrate the cells of the body and reach the image receptor (film or plate), resulting in increased film density (compared to lower energy beams that may be absorbed in the …
