	Medical ultrasonography - Wikipedia, the free encyclopedia
		Medical ultrasonography (sonography) is an ultrasound-based diagnostic imaging technique used to visualize muscles and internal organs, their size, structure and any pathological lesions, making them useful for scanning the organs.
		In medical ultrasonography, a sound wave is typically produced by creating short, strong pulses of sound from a phased array of piezoelectric transducers (usually a type of ceramic).
		Medical ultrasonography was used 1953 at Lund University by cardiologist Inge Edler and Carl Hellmuth Hertz, the son of Gustav Ludwig Hertz, who was a graduate student at the department of nuclear physics.

	Medical imaging - Wikipedia, the free encyclopedia
		Medical imaging is the process by which physicians evaluate an area of the subject's body that is not externally visible (this may be termed clinical imaging), and could therefore involve any medical discipline, and scientists researching into new methods of creating these images.
		The medical specialist directing medical imaging is a radiologist, and the medical aspects are known as radiology.
		Medical ultrasonography uses high frequency sound waves of between 2.0 to 10.0 megahertz that are reflected by tissue to varying degrees to produce a 2D image, traditionally on a TV monitor.

	Ultrasonography Information on Healthline
		Ultrasonography is a diagnostic technique that involves directing high frequency sound waves at tissues in the body to generate images of anatomical structures.
		Ultrasonography is also called sonography, diagnostic sonography, and echocardiography when it is used to image the heart.
		Cranial ultrasonography is most often used in infants to diagnose problems with the brain and the ventricles in the brain through which cerebrospinal fluid (the clear fluid that circulates through the brain and spinal cord) flows.

	Medical Ultrasonography
		Medical ultrasonography is a diagnostic imaging technique that uses ultrasound equipment.
		Ultrasonography was invented in 1953 at Lund University by cardiologist Inge Edler and Carl Hellmuth Hertz, a graduate student studying nuclear physics.
		The sound frequencies used for medical ultrasonography are generally in the range of 1 to 10 MHz.

	Inge Edler and Carl Hertz, history of ultrasonography
		In 1953, Inge Edler was in charge of the Cardiology Department at the University Hospital, Lund, Sweden and was in the position responsible for the preoperative diagnosis of heart disease.
		Edler was cited for pioneering the clinical application of ultrasound for the medical diagnosis of abnormalities of the heart.
		His work at Donald's department had resulted in the shipment of the second generation Diasonograph® to Lund, with which he produced his doctoral thesis on the use of ultrasound in Obstetrics and Gynecology, and reported his experience on 400 cases of pelvic pathologies.

	Medical Imaging and Machine Vision - Machine Vision Online
		Medical imaging is a process by which physicians examine and evaluate an internal part of the human body for either diagnostic or research-related reasons.
		The origins of medical imaging can be traced back to 1895 when Wilhelm Roentgen used a cathode-ray ray tube to make the very first radiograph, an x-ray image of his hand.
		Another aspect of the medical imaging market that should encourage machine vision companies to target this market is the growing trend away from the use of x-ray film.

	Screening for ovarian cancer
		Ultrasonography may be useful in discriminating benign from malignant adnexal masses.[4] Transvaginal ultrasonography has been proposed as a screening method for ovarian cancer because of its ability to reliably measure ovarian size and detect small masses.[5] The benefit of ultrasonography for the early detection of ovarian cancer has not been evaluated in controlled studies.
		Transvaginal ultrasonography was used in a study of 3,220 asymptomatic, postmenopausal women.[8] Forty-four women (1.4%) had persistent abnormal scans and underwent exploratory laparotomy.
		In one other study, transabdominal and transvaginal ultrasonography were both used to screen 1,601 self-referred women with a first- or second-degree relative with ovarian cancer.[9] Sixty- one had positive screening tests; 6 had ovarian cancer that was detected at surgery (5 of 6 had stage I disease).

		Toshio Wagai was born in 1924 in Sendai, Miyagi Prefecture.
		A true pioneering figure in ultrasonography, Wagai has received numerous prizes and awards and many of them were conferred on him by the Japanese government and international organizations.
		Ultrasonic doppler techniques were first implemented by Shigeo Satomura and Yasuhara Nimura at the Institute of Scientific and Industrial Research in Osaka, Japan in 1955 for the study of cardiac valvular motion and pulsations of peripheral blood vessels.

		Ultrasonography can be used to evaluate pelvic pain, a common complaint of patients presenting to the ED, and entities such as ovarian cysts, tubo-ovarian abscesses, uterine fibroids, or even an infected pelvic kidney.
		Ultrasonography can aid in the localization or detection of an intrauterine device or foreign body.
		The biggest pitfall of using ultrasonography in the ED is missing a diagnosis of an ectopic pregnancy.

		If the abdominal signs are sufficiently clear to indicate peritonism in the right iliac fossa in elderly patients or female patients of reproductive age there is little to be gained from ultrasonography.
		Then the task among the remainder is to distinguish, with the minimum of delay, those with suspicious signs who are developing surgical or medical disease requiring treatment from those with non-specific abdominal pain.
		When the frequency of non-specific abdominal pain is not allowed for there is a tendency to regard every doubtful case as a possible perforated appendix, and this still leads to as many as 15-30% of appendicectomies being unproductive.

	Clinical Trial: De-Medicalizing Mifepristone Medical Abortion
		This study will investigate the possibility that medical abortion using mifepristone and misoprostol - a safe, proven therapy for terminating early first trimester pregnancy - can be administered in a manner that is simpler and less costly than that routinely employed in the United States.
		Furthermore, as medical abortion employs medications rather than surgery to terminate a pregnancy, it has the potential to greatly increase the availability of locations providing abortion services in the US, eliminating as it does the need for expensive equipment and surgical training.
		The purpose of the current study is to test the feasibility and efficacy of an approach to medical abortion that forgoes the routine use of ultrasonography.
