Based from the objectives below, (1 explain that X-rays are produced by electron bombardment of a metal target and calculate the minimum
wavelength of X-rays produced from the accelerating p.d.
2 understand the use of X-rays in imaging internal body structures, including an understanding of the term
contrast in X-ray imaging
3 recall and use I = I0e–μx for the attenuation of X-rays in matter
4 understand that computed tomography (CT) scanning produces a 3D image of an internal structure by
first combining multiple X-ray images taken in the same section from different angles to obtain a 2D
image of the section, then repeating this process along an axis and combining 2D images of multiple sections. ) rewrite my script, while retaining originality mostly or add on any you deem fit to be of relevance, to remove any unnecessary parts. Do not try to end the response short, as you must include parts of my original script. Here is my original script: "
So what is medical imaging?
Medical imaging is the non-invasive technique and process of creating visual representations of the interior of a body, such as tissues, organs or body parts for use in clinical diagnosis, treatment and disease monitoring.
Imaging techniques involve the fields of radiology, nuclear medicine, optical imaging and image-guided intervention.
This is an example of what medical imaging looks like, and I'm showing you this early but you'll understand later.
The nature and production of X-rays.
X-radiation is a high-energy, high frequency electromagnetic radiation, that has wavelengths shorter than ultraviolet rays and longer than gamma rays.
Generally, there is no strict, accepted definition of the bounds of the X-ray band.
But, roughly, it is distinguished by their short-wavelength ranging from 10^-8 to 10^-12 meters, matching to frequencies in the range of 3×1016 Hz to 3×1019 Hz and photon energies in the range of 100 eV to 100 keV, respectively.
All E.M. radiation share the same basic properties but X-rays and gamma rays are different from the rest in that they just have a higher energy than the rest and have enough of it to be called ionizing radiation.
Why I’m talking about gamma rays is because it’ll be included later on in PET scans.
So Ionizing radiation are E.M. waves that have enough energy to ionize atoms by knocking out electrons from them.
Gamma rays, X-rays, and the higher energy ultraviolet part of the electromagnetic spectrum are ionizing radiation, but the lower energy ultraviolet, visible light, infrared, microwaves, and radio waves are non-ionizing radiation.
The boundary between ionizing and non-ionizing radiation in the ultraviolet area cannot be sharply defined, as different molecules and atoms ionize at different energies.
Generally, the energy of ionizing radiation starts between 10 electronvolts (eV) and 33 eV.
Another thing about boundaries in the E.M. spectrum is that it is continuous like the range of colors in Visible light, so there isn’t any exact point where one starts and ends.
Hence, why I said the X-ray band doesn’t have a specific, defined range.
And some also overlap in the E.M. spectrum, such as X-rays and gamma rays.
How scientists distinguish these waves, they separate by their origin:
X rays are emitted by atoms, outside the nuclei, when electrons jump from higher to lower energy states. While gamma rays, are emitted through a nuclear reaction, within the nucleus.
As they are outside the range of the visible spectrum...
X-rays are invisible to our eyes but visible images can be produced if we use photographic plates or special detectors.
The kind of image produced, used to visualize any interior, is due to using the nature of X-rays.
Same nature as visible light concludes that X-rays can be thought of as waves or particles (photons) from Quantum Mechanics.
All E.M. radiation are made of individual packets of energy called photons, and each photon, in an E.M. wave, is a packet of energy that carries a specific amount (eV).
Like all particles, energy can be transferred from one medium to another when interacting with other matter…
Photons act as individual quanta and can interact with individual electrons, atoms, molecules, and so on. 
The energy a photon carries is, thus, crucial to the effects it has.
If it has enough energy, it can knock an electron out from an atom.
Thus, we say that X-rays can ionize atoms. 
With one photon that can potentially creating thousands of ions in materials that happen to absorb them.
Imagine that a single gamma ray photon has about 4.14 Mega electron volt, which is 10^6 and about 10 to 1000 eV are only needed for one ionization. 
It would ionize atoms in your body over 4 thousand or 400 thousand times, causing heavy damage to cells and disrupting cell reproduction, causing cancer.
X-rays originate in the electron cloud of an atom.
Most X-ray devices emit electrons from a cathode, accelerate them with a voltage, and allow them to hit an anode, going through either two processes  that can be classified as Bremsstrahlung or Characteristic. 

This is a process that generates a lot of heat, so that X-ray tubes must be very well chilled. An alternative to conventional X-ray tubes are the rotating anode generators, in which the anode in the form of a cylinder is maintained in a continuous rotation, so that the incidence of electrons is distributed over its cylindrical surface and thus a higher power can be obtained.
Sometimes the electron comes very close to a nucleus in the target and is deviated by the electromagnetic interaction. 
In this process, which is called bremsstrahlung (braking radiation), the electron loses a lot of energy and a photon (X-ray) is emitted.
 The energy of the emitted photon can take any value up to a maximum corresponding to the energy of the incident electron. 
The high energy electron can also cause an electron close to the nucleus in a metal atom to be knocked out. This vacancy is filled by an electron further out from the nucleus. The well defined difference in binding energy, characteristic of the material, is emitted as a monoenergetic photon. When detected this X-ray photon gives rise to a characteristic X-ray line in the energy spectrum."
