Ultrasound Imaging An Ultrasound Machine - 1291 Words

The photo on the right shows a medical technician using an ultrasound machine to diagnose appendicitis to a patient, without the use of x-rays. The ultrasound imaging technique involves using high frequency sound waves and their echoes. The machine transmits high-frequency sound pulses into the patient’s body using a probe. In the image, the technician presses and moves the probe along the patient’s body. This photo was taken in the St. Louis Children’s Hospital. A wave is a traveling disturbance that carries energy from one place to another. Ultrasound-imaging machines use waves to produce real time images of patients’ organs and tissues to complement diagnosis. The frequency of a wave refers to the number of waves passing a point at a certain time. An ultrasound is a type of wave that has a frequency exceeding the upper limit of human hearing (greater than 20,000 hertz). However, diagnostic ultrasound machines usually use frequencies in the order of 1-10 million hertz. The frequency of waves is very important, as it is very specific when using these instruments. It is imperative to consider that the speed of sound depends on the specific properties of a medium. Therefore, these concepts must be taken into consideration when manufacturing and getting prepared to use such instruments. The wavelength is the distance between two identical peaks in the wave cycle. It is one of the main factors that affect the resolution of an ultrasound image. As the wavelength of a waveShow MoreRelatedCase Study : Micro Vex Probe Ultrasound1039 Words   |  5 PagesEngineering Girl Essay: Micro-Vex Probe Ultrasound One promising new technology related to engineering is ultrasound probes which are used in Veterinarian Medicine also considered as a part of Biomedical Engineering.

Minimally invasive medical techniques can be defined as surgical procedures that require the smallest incision into the skin. Examples of minimally invasive medical techniques include keyhole surgery and laser eye surgery. 2. Discuss the advantages and disadvantages of non-invasive and minimally invasive medical techniques. Non-invasive medical techniques have proven to be advantageous. Imaging techniques are advantageousRead MoreComparison of X-Ray and Ultrasound1217 Words   |  5 PagesX 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 bodys 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 radiographyRead MoreCase Analysis: Disruptive Technology a Heartbeat Away: Ecton, Inc.1250 Words   |  5 PagesPackard exceeds 60% of the major cardiac ultrasound manufacturing, which equals to $ 470.4 million.

This enables doctor’s to treat patients before their condition deteriorates. This procedure would not be possible without the use of X-rays, CAT scans, MRI scans, ultrasound and endoscopes, which allow doctors to see inside the body with little or no surgeryRead MoreThe Visual Representation of a Body Part in Imaging Technology1068 Words   |  4 PagesImaging technology is the visual representation of a body part, such as an organ, for the purpose of a medical diagnosis. Nowadays, technologies such as X-Rays, Magnetic Resonance Imaging (MRI) and ultrasound are used everyday for medical analysis. X-Rays are very useful because they can penetrate through different materials to give an image of the interior of the body. MRI use strong magnets to create an image of a body part, while ultrasound imaging uses sound waves. Bone, muscle and fat absorbRead MoreEcton Inc. Case Analysis Essay1572 Words   |  7 Pagesa.
