    Increasing kVp does NOT increase the amount of scatter photons produced( 2:40). As kVp increases, the photons are more likely to pass through without interacting at all. If they do interact and scatter, they will scatter with greater retained energy and are more likely to reach the IR, thus causing worse scatter fog despite fewer raw numbers of scattered photons.

    2:20 you said mA we selected adjusts the rheostat and sends the current to either large or small focal spot. I think you meant to say it sends the current to either large or small filament correct? From what I've learned the focal spot is located on anode itself. Am I getting this right? Also, thanks for the video - very helpful

    I presented papers at the national conference in Australia in 1988 and again in 2016 because radiographers did not know that pushing the tube angle button and angling did not change the relationship between tube focus and patient. The only thing that changes with tube angulation is collimation. At the last conference there were 120 qualified radiographers and only 25% knew what happened when the tube was angled. th-cam.com/video/mZPD_gLs5Dw/w-d-xo.htmlsi=e5HMqOBuOfOlomlu. Some of the xray tubes I used in the early 80s had 1mm small focus and 2mm large focus, so nothing was sharp

    To use a focused grid successfully you will need to understand the geometry of each projection. Tube angulation only changes collimation, so the beam can be directed toward the edge of a grid without any cut-off. Here is the test that 75% of qualified radiographers fail. th-cam.com/video/mZPD_gLs5Dw/w-d-xo.html

  • @abdovitamins6331
    @abdovitamins6331 2 ปีที่แล้ว

    Sir i am so confused. According to what you explained and also as mentioned in Farr's physics ( increasing kV dose increase scatter, and decreasing kV does reduce scatter) The RCR put a sample of MCQS, one of them was : High energy radiation is scattered more than lower energy radiation. Then my answer was true, but when i went to revise my answer infound it false because there answer was false !! So i am so confused. Can you help please?

    • @michael_nel
      @michael_nel 2 ปีที่แล้ว

      Lots of people find this confusing. Increasing kV results in less attenuation and less scatter radiation (more of the x-rays are transmitted and less are attenuated via photoelectric effect and scattered via compton). It is the photoelectric effect and compton scatter that contribute to anatomic detail and spatial resolution. At higher kVs compton scatter is proportionally more than photoelectric effect despite both being reduced at higher kVs. At lower kVs photoelectric effect predominates - therefore, there is proportionally less scatter. I hope this makes some sense. At low kVs there is technically more scatter but proportionally there is more scatter at higher kVs.

    • @KuumaTheBronze
      @KuumaTheBronze 2 ปีที่แล้ว

      As you knock electrons out of their inner shells you produce secondary radiation in the form of Characteristic radiation, rather than Brem, which can then continue the process of scatter as the secondary radiation interacts with tissue/matter around it.

    • @nikkiw3856
      @nikkiw3856 3 ปีที่แล้ว

      Hi, I can't be exactly sure, but I believe your physics teacher may have been inferring that the direction the diode is pointing correlates to the conventional electric current (electricians practice under the impression that electricity flows positive to negative as a result of Ben Franklin's discoveries). Physicists know that current is in the direction of electron flow, which is opposite the direction from where the diode is pointing.

    • @alexwang007
      @alexwang007 ปีที่แล้ว

      The "conventional current" flows from positive to negative, towards where the arrow points of a diode. Electrons, flow from negative (cathod) to positive (anode)
