Positron Emission Tomography Research Paper

985 Words4 Pages

The world around you is full of waves. Waves can be anywhere, it can be in the air you breathe and the sound you hear, waves could be in ocean ripples and in the sunlight energy you get heat from. A wave is a disturbance that transfers energy from one place to another, some types of waves need a material to travel through which is called a medium. There are types of waves, one type of wave is a longitudinal wave, this type of wave has particles that move back and forth in the same direction of the wave. Sound waves are longitudinal wave; longitudinal waves need a medium to travel through. In the same time, transverse waves, another type of waves, doesn’t need a medium to travel through, and the particles in it move perpendicularly to the direction of the wave. Positron Emission Tomography or ‘PET’ is a type of scan that examines the shape, size and behavior of the organs in your body. Created by a physicist and scientist named Wilhelm Röntgen, he designed and produced Radiography in 1896, it used something called x-rays, which is an invisible radiation, which is also discovered by him. Then this type of …show more content…

PET scans have a variety of advantages and disadvantages, some of the advantages are, it can scan your body for the functions of the organs. Next is that it can detect any disease and the percentage of its spreading. Furthermore, this device has the ability to understand if you have non-cancerous and cancerous diseases. Finally, this machine can recognize the primal stages of diseases and tumors. PET scans also have disadvantages such as; in these scans have a material that may cause some problems for women that are pregnant. Shortly after it comes that you should pay much more than the other scans such as MRI scans and x-ray scans, which exceeds from $900-$1400. Last of all is that PET imaging requires a machine that produces the radioactive material which is expensive to

    Unit D Summary: Light and Geometric Optics 10.1 : Light and The Electromagnetic Spectrum Chapter 10.1 covers light and the electromagnetic spectrum. This chapter starts off by describing how light is a form of energy that travels in waves. The properties of said waves include a crest (the highest point of the wave), the trough (the lowest point of the wave), and the rest position (the level of a wave without energy).

  • Longitudinal Waves By Jason Torres Summary

    187 Words  | 1 Pages

    In "Passage 1: Sound is All around Us, Sound is Energy" Jason Torres claims that sound is a form of waves that vibrate in one directions called longitudinal waves. "The distance between two adjacent compressions, two adjacent rabout the longitudinal arefactions, or a single compression and rarefaction combined is a wavelength of a sound wave. " This is Jason Torres ' definition of Longitudinal Waves. The wave measures the sound and pitch. This pitch and sound can differ due to the extent of energy/waves released.

  • Australian Health Care System Essay

    Diagnostic imaging providers in this region are permitted to set their own fees for services.11 With the proper accreditation and verification of the location where the services were provided, Australia’s Medicare plan should cover a portion of the cost.4,11 The remaining balance would be paid out-of-pocket by the patient or paid by other forms of coverage, such as private health insurance. For patients who do not have another form of coverage other than Medicare, these remaining costs may present a challenge for those of lower incomes, especially for more advanced imaging studies like CT or MRI. This is one issue with equal accessibility to healthcare services in the country. To combat this issue, I would suggest increasing Medicare’s coverage for diagnostic imaging services and develop a government assistance program for the less fortunate to enroll in to offset the out-of-pocket costs for medical services.

  • Physics Of Ultrasound Essay

    The mechanical vibrations transmitted through a medium; solid, liquid or a gas generates a sound wave. The sound is an energy, which deflects the particles of a medium in the same direction, and itself travel as a longitudinal waveform with areas of compression and rarefactions. The image generated by ultrasound is essentially based on similar principle by means of a machine, which includes an ultrasound transducer and a screen. The transducer contains a piezoelectric crystal made up of lead zirconite, which generates an ultrasound beam on applying an electrical current to the transducer. These signals travel through a medium in the body and after striking with various tissues, return back to the transducer.

    Waves travel through medium or matter. When someone speaks, they send out a pressure disturbance in the air. You can also create a wave by using a rope or string. Use what you know about waves and energy to design and carry out an investigation that will allow you to describe the relationship between a wave’s energy and its amplitude, wavelength and frequency.

    Each imaging modality is characterized primarily as being able to render high-resolution images with good contrast resolution (anatomic imaging) or to render images that depict tissue function (functional imaging). Anatomic (Structural) Imaging Imaging the structure of the body has been and continues to be the major application of medical imaging, although, as described in 9.2.2, functional imaging is a very active area of research. The goal of anatomic imaging is to accurately depict the structure of the body—the size and shape of organs—and to visualize abnormalities clearly. Since the goal in anatomic imaging is to depict and understand the structure of anatomic entities accurately, high spatial resolution is an important requirement of

    Some advantages of this technique are that there is no radiation involved, it is good at visualizing soft tissue, and that since it can visualize soft tissue so easily it can identify a multitude of different problems. Some disadvantages are that it is time consuming, expensive, and there is extensive training needed to operate it. The last type of imaging technique that will be covered is conventional radiography which can detect foreign bodies and changes or lesions of the skeletal system and is used when the corpse cannot fit into the CT machine. The advantages of this technique are that it is simple, quick, and cost efficient. However, it uses radiation, cannot make three-dimensional reconstructions, has a superimposed image, and it cannot visualize soft tissue
