An ap x-ray still requires them to stand, but allows for the patient to be hunched over. The drawback is that the x-ray will have a larger magnification and less detail.
Even with these risks, x-ray scanning is still a safer option than surgery. X-ray machines are an invaluable tool in medicine, as well as an asset in security and scientific research. They are truly one of the most useful inventions of all time. For more information on x-rays and x-ray machines, check out the links on the next page.

However, x-ray beams are typically filtered to minimize the low-energy component. •low-energy x-rays are not useful in radiography, but can deliver a significant dose. •whenever the voltage is on, a device can produce some x-rays, even if the current is too low to read.
X-rays are like light rays, but they can pass through more stuff. Some of the x-ray's energy is blocked by bone, which is why you can see bones so clearly on x-ray scans.

Radiographic interpretation is based on the visualisation and analysis of opacities on a radiograph. One can easily identify a fracture or misalignment in the continuity.
Both are wavelike forms of electromagnetic energy carried by particles called photons (see how light works for details). The difference between x-rays and visible light rays is the energy level of the individual photons.

Chapter 1 provided a general discussion of the x-ray tube head assembly and the function of the major parts of the design. Chapter 4 discussed the components of the x-ray circuit and the events that lead to the production of x-rays in the x-ray tube. This chapter examines the x-ray tube itself its general construction, and how it works.
