X rays and Ultrasound are two of the main imaging techniques used in radiography. For the purposes of this essay‚ we will look at conventional x-rays and diagnostic ultrasound. Conventional x rays are non-invasive diagnostic techniques that are used to capture images of the body’s organs and bones. Diagnostic ultrasounds are high frequency sound waves to create an image of soft issues in the body such as muscles‚ joints‚ and internal organs. As examined below‚ while both are used in diagnostic radiography

erupt are the mandibular central incisors (lower)‚ then the maxillary central incisors (upper) this usually happens at the ages of 6 months to 12 months. The anterior portion of the mouth is the first to erupt‚ then the posterior follows. Sometimes infants are born with teeth‚ these are called neonatal tooth‚ in some cases the these are lost soon after birth. Tooth development normally starts in the 3rd to 6th months of pregnancy. When teeth erupt they normally come in pairs‚ such

components of an X-ray Tube? The x-ray tube consists of an electrode pair - a cathode and an anode. The cathode is a negatively charged heated filament made from tungsten. The anode is a positively charged flat disc‚ also made from tungsten. The electrode pair sits inside a glass vacuum tube‚ which is lined with lead for protection. 2) State the two interactions that occur in the X-ray tube to produce the x-ray beam Bermsstralhung interaction and Characteristic interaction. 3) The X-ray beam is attenuated

X-rays and Ultrasound: X-rays and ultrasound are two different modalities used for different things‚ so an ultrasound can do some things an X ray cannot‚ and vice versa‚ and so this makes them very difficult to directly compare. Ultrasound: Above: An ultrasound machine. Ultrasound is the use of energy generated by sound waves of 20‚000 or more vibrations per second. Ultrasounds are generated by a device called a transducer. Bearing in mind that sound is a mechanical energy‚ the transducer

Conrad Rontgen‚ a German‚ accidentally came upon the x-ray. The x-ray is a complex piece of technology that airports and hospitals use greatly in life today. In the medical world the x-ray has helped find diseases when no other piece of technology could. The x-ray is a very important machine that our world couldn’t do without. Rontgen accidentally discovered the x-ray when he was studying the effects of the cathode ray. He found that the x-ray could light up a screen a few meters from the source

Radiology is the process of working and viewing inside the human body without breaking the skin. By using radiant energy‚ which may take the form of x-rays or other types of radiation‚ we are able to diagnose and treat many diseases and injuries. Both diagnostic and therapeutic radiology involve the use of ionizing radiation (Beta‚ Alpha‚ Gamma‚ and x-rays)‚ with the exception of the MRI‚ which uses a magnetic field rather than radiation. Radiology is classified as being either diagnostic or therapeutic

individual determine his or her own success? Success is determined differently by each person. Some might find having a big home successful‚ and some might find having a happy family is all they need to feel that they succedded in life. It all comes down to how you were raised and how you preseve the world. Why everyone determines success differently is determined by many factors‚ including your location in the world‚ gender‚ age‚ spirituality‚ and many other factors. How someone should determine their

X-ray Absorption Spectroscopy X-ray absorption spectroscopy (XAS) techniques probe short- and medium-range order‚ yielding information on bond lengths‚ coordination numbers‚ local coordination geometry and the oxidation state of atoms for a wide range of solid and liquid systems. XAS experiments require an intense‚ tunable photon source only available at synchrotrons. Features • medium and high energy (from atomic number Z=20 upwards) XAS‚ XANES (x-ray absorption near-edge structure)

Applications of X-Rays We see X-Rays all the time in television‚ science fiction novels‚ and comic book superheroes‚ but what is fact and what is fiction? By examining their makeup‚ history‚ modern applications‚ dangers‚ protection‚ and even possible future developments we can understand these scientific marvels far better and more accurately than watching an episode of Star Trek or reading a Superman comic. First and most important is to analyze why an X-ray works and what it is. These “rays” are high
