Limitations to using a x-ray

The limitations of using a x-ray is that an x-ray can expose you to radiation which is harmful to the human body. This is why when your at the dentist the put a vest on you to prevent allowing you to get radiation. Although one you do your body there not much to cover because you don't wont it to ruin the x-ray. As well as that it's not the best kind of device when you compare it to the other image methods. This means that it just gives the basic needs that you need but there are greater technologies that allow you to get a better picture.

Advantages of using an X-ray

A advantage to getting an X-ray is that it is able to produce a picture of any part of the body. So it is very helpful when you break a bone. They are also able to detect a problem that can be missed by a human eye. This becomes very helpful when it comes to tumors. Another reason is for financial reasons out of the other picture scanning machines (MRI or CT etc.) an x-ray is the cheapest one. It is also available as a portable device so that if there an emergency your still able to get one.

Fun fact

X-rays are not only used for medical reasons you can also find x-rays in airports to make sure all passengers are safe and so that no one is able to sneak on weapons on a plane.

How does it work?

How does a x-ray work?
The way an x- ray works is by using electromagnetic rays that penetrate the skin so the bones and tumors and muscles appear. This happens because when the x-rays hit the film they let out a light and since the muscles and bones and tumors all absorb a certain amount of light they all have different shadows allowing you to tell the different between them.

How does the x-ray machine work?

 The way a x-ray machine works is by using a electrode pair which is a cathode and an anode what happens with this is that it creates an electron beam that sits in a glass vacuum. Then the cathode is a heated filament the machine then passes current through it so it can create electrons with the positive charged disc of anode the voltage between the cathode and the anode are a huge difference which results in a x-ray.

In this diagram I see the how the machine would work and how the electrons travel and become an x-ray.

What is the purpose of a x-ray?

The main purpose of using the x- ray in medicine is to detect problems in the body, x-rays can be used to detect broken bones, dental decay as well as tumors. X-rays are not only meant for bones and teeth there are chest x-rays that allow you to see lung diseases, there is also abdominal x-rays which shows you if you have any thing disturbing your small and large intestines, it shows you if you have gall bladder or kidney stones as well as fluid collection in your abdominal cavity. So you would see doctors and dentist use this machine for their daily jobs and these machines allow us to learn a lot about the body without having to cut it open.

What is a X- ray ?

The x-ray was first discovered in  1895 by a German scientist Wilhelm Conrad. Conrad had discovered that using streams of x-rays through someones arms or legs show very detailed pictures of the bones inside of them. Making it easier for doctors and dentist all over the world today.

Introduction

Hello everyone this is my blog for a science ISU. This blog's main focus will be on X- rays, I will break it down into  the purpose of what an X-ray is capable of doing, how it works, the advantages and disadvantages so I hope you enjoy my blog :)
