All You Need to Know About C Arms

The term "C Arm" refers to a piece of machinery that has become widely used in hospitals through the past five decades. The C Arm (also called an x-ray image intensifier and Fluoroscope) uses x-ray images to create a "live feed" that is then displayed on a TV screen.

The fluoroscopy technology associated with C Arms was released to the public in 1955. In the 21st century, there are a only a few larger manufacturers of C Arms.
There are two common ways that C Arm machines are used: as a fixed piece of equipment that is kept in one particular screening room and isn't portable, or as mobile machine that can be used in a theatre for lectures and other demonstrations.

Fixed C Arms are used in most of the hospitals across the country, and for many different reasons. Some common situations that might require the use of a C-Arm are barium studies, therapeutic studies, fertility studies, endoscopy studies, cardiac studies, and angiography studies.

Mobile C Arms are slightly smaller than their fixed counterpart, making them easy to transport to various and different locations. As technology continues to grow throughout time, mobile C Arms continue to improve and become more and more powerful.

Mobile C Arms are used in hospitals across the nation for various reasons including therapeutic procedures in theatre, endovascular imaging in theatre, neurological imaging in theatre, and orthopedic imaging in theatre.

C Arms are very accurate pieces of machinery, so they are obviously very desirable to professionals in the medical field. There are also many reasons that C Arms are attractive to patients as well.

C Arms help to reduce the amount of discomfort that the patient feels. When hospitals use C Arms during surgical or non-surgical procedures, invasiveness is minimized.

As far as money is concerned, the use of C-Arms leads to more cost-effective outpatient care in hospitals.

The diversity of C Arms is also a factor that attracts the medical field; these machines can be used during orthopedic, spinal, and general surgeries as well as with cardiac, vascular, and neurovascular applications.

X-ray lab technicians undoubtedly appreciate the fact that C Arms are very easy to use. Also, doctors and physicians certainly enjoy the accurate and instant information that these pieces of equipment are able to report.

Since the C Arm was invented in the 1950s, the technology has continued to grow and improve. The many benefits that accompany using the C Arm speak for themselves: this technology has greatly improved the medical field.

Science Projects For 4th Grade

The fourth grade is usually a transitional period in your child's education. Your children are not in the lower grades anymore. They are expected to do more when it comes to school work. There are higher standards are expected to hold when it comes to science projects for 4th grade. The static electricity and balloon project might just be too childish for you growing child. The teachers will be expecting more.

Luckily, 4th grade science projects are actually not that difficult to do. With your help, you and your child can successfully create an excellent project for the fair. Here is one of many science projects for 4th grade:

Materials You Need

1. spoon
2. blank sheet of white paper
3. pencil
4. matches (Be careful, you might want to help your child handle these.)
5. beaker
6. glass
7. glass stirring rod
8. potassium or sodium nitrate (you can buy this chemical from science companies)
9. Camera or video recorder

Procedure (instructions)

1. Take the glass beaker and pour one cup of water into it.

2. Take the potassium or sodium nitrate. Measure out about one half of a teaspoon. Pour it into the beaker.

3. Use the glass stirring rod and stir until all the chemicals dissolve in the water.

4. Keep adding one half teaspoons of the chemicals to the beaker. Stir using the rod. When the chemicals stop dissolving in the beaker and begins to build up on the bottom, it is time to stop. You now have your solution ready.

5. Take the blank sheet of white paper. Dip your glass stirring rod into your solution. This solution is now your "ink." Draw! Draw any design you want on your paper. Don't be afraid to overuse. Make sure your lines are thick with solution.

6. Using a camera, take a picture of your paper, still wet from your sketching.

7. Let the paper dry a bit.

8. Before the lines of the solution disappear, take the pencil and mark an area of the drawing.

9. Now it is time to record our results. Have someone start the video recorder. Focus it on the drawing.

10. Take a glass and fill it up with water. Have an adult strike a match. Hand the glowing tip to the child. Get ready!

11. Have the child touch the spot on the paper that was marked with the pencil.

12. Film what happens! Take pictures. Get before and after shots of the paper to put on the science project board.

13. Done! You have just finished one of the science projects for 4th grade.
