In this instance, the sonographer did not ask for the girl's permission to share information with her parents. It is true HIPAA gives considerable leeway to healthcare providers for underage patients: "a provider may withhold information from a parent/personal representative if 'in the exercise of professional judgment…it is not in the best interest of the individual to treat the person as the individual's personal representative,' as in the case of an abusive parent (Minors, 2005, Miller School)
The screenings can confirm the health of the fetus. it's becoming more common for women to have screening sonograms during their first trimester" depending upon their medical condition and/or age (Orenstein 2010)
d.) Based on the piezo-electric effect discovered by the Curies, transducer crystals give output energy or a signal in the form of a visual or readable image (Carlson, 2009, p
In 1880, Pierre Curie and Jacques Curie discovered the Piezo-Electric Effect (Tsung, 2011, p. 5), which is an electrical charge created by mechanical stress (Piezo Systems, Inc
Then in the 1950's, American physicians Douglass Howry and Joseph Holmes developed two-dimensional B-mode ultrasound, particularly the "pan scanner." The pan scanner was a significant breakthrough in that it did not require a subject to be fully immersed in order to use a focused sound beam and compound scanning for two-dimensional results (Posakony, n
Ultrasound Physics began in 1794 with a certain observation by an Italian physiologist named Lazzaro Spallanzani. Spallanzani noticed that flying bats use ultrasound in the form of "echolocation" to guide them (Tsung, 2011, p
The concept of high-frequency sound waves, or "ultrasound," had been around since the late 18th century when an Italian scientist began exploring the natural navigational system used by bats. In 1876, Francis Galton developed the Galton whistle, which was capable of producing the high-frequency sounds, however, "The real breakthrough in the evolution of high frequency echo-sounding techniques came when the piezo-electric effect in certain crystals was discovered by Pierre Curie and his brother Jacques Curie in Paris, France in 1880" (Woo, 1)
Ho et al. states that arterial puncture and arteriovenous fistula "are recognized complications of internal jugular vein cannulation" (Ho, Spanger, Hayward, McNicol, Weinberg, 2014, p
As Jian et al. discovered as early as 2006 "high frequency transducers can provide images of subsurface structures with microscopic resolution" (Jian, Yuan, Jiang, Pei-Jei, Sadake, Bautista, Snook, Rehrig, 2006, p
¶ … History of Ultrasound Physics and the Properties of the Transducer Today, innovations in medical imaging allow clinicians to view the soft tissues, organs and blood flow inside the human body in ways that provide the opportunity for early diagnosis and treatment of a wide range of disorders as well as to monitor neonatal health (Goldberg & Verny, 2007)
179). Ultrasound physics relate to a physical or electromagnetic wave that is capable of interacting with some type of object; the extent of the interaction, or the crests and waves that are created, is a function of the size of the object versus the radiation wavelength that is used (Levine, 2010)
Contemporary ultrasound machines are less burdensome and more user friendly in comparison to older ones. The main goal of the study encompassed evaluating the viability of conveying an ultrasound-based course to undergraduates and to discover the perceptions of the students as well as those of teachers in this auspicious teaching modality (Hammoudi et al
With the advancement of technology and introduction of computer and virtual models as well as simulation, plenty of changes have been instigated. In comparison to virtuously virtual dissection, the ultrasound method permits the efficacious visualization of huge anatomical structures, and makes it possible for medical students to handle the transducer in a manner through which they grip the scalpel and the anatomical pincers (Mircea et al

Learn an ultrasound procedure, and conditions and diseases it assists in diagnosing and screening like tumors, cysts, heart conditions and more.
Ultrasound — Overview covers definition, risks, results of this procedure.
Medical ultrasound (also known as diagnostic sonography or ultrasonography) is a diagnostic imaging technique based on the application of ultrasound.
