| 4D Ultrasound |  |
| |
|
As far as ultrasound is concerned, 4D ultrasound (also referred to as live 3D ultrasound or 4B-mode) is the latest ultrasound technology - the fourth dimension means length, width, and depth over time. 4D Ultrasound takes 3D ultrasound images and adds the element of time to the progress so that a moving three-dimensional image is seen on the monitor. A 4D scan takes the same amounts of time as a 2D or 3D scan; the difference is the ultrasound equipment being used. One advantage of a 4D fetal ultrasound to a 2D-mode is that parents can see how their baby will generally look like. However, there are different opinions over the medical advantages.
To scan a 3D ultrasound image, the probe is swept over the maternal abdomen. A computer takes multiple images and renders the 3D picture. With 4D imaging, the computer takes the images as multiple pictures while the probe is hold still and a 3D image is simultaneously rendered in real time on a monitor.
In most cases, the standard 2D ultrasound is taken, and then the 3D/4D scan capability is added if an abnormality is detected or suspected. The 3D/4D sonogram is then focused on a specific area, to provide the details needed to assess and diagnose a suspected problem. A quick 4D scan of the face of the fetus may be performed at the end of a routine exam, providing the parents with a photo.

| ESAOTE S.p.A. | |
| |
|
The Italian based company is a member of the Bracco Group.
In 1988 Ote-Biomedica Elettronica S.p.A. and the biomedical division of Esacontrol S.p.A. were consolidated into a single company, Esaote Biomedica S.p.A., operating as a division of IRI-Finmeccanica.
In 1987 the company began marketing its products in the United States through Biosound Inc., which it subsequently acquired in 1990.
In the 1990's, the company began to strengthen its presence in Europe, establishing Esaote Biomedica France Sarl and Esaote Biomedica Deutschland GmbH.
In July 1994 business activities and assets of Esaote Biomedica S.p.A. were transferred to the new company Esaote S.p.A.
1995-1998 the Bracco Group becoming the main Esaote shareholder with 50% of the share capital.
In February 1997, Esaote established Esaote China Ltd. located in Hong Kong, and in April 1998 acquired Pie Medical Group, based in Maastricht - The Netherlands, which primarily operates in medical diagnostic ultrasound.
Esaote-Pie Medical, is exclusively dedicated to the development and marketing of veterinary diagnostic ultrasound equipment.
GE Healthcare is the exclusive U.S. distributor of devices manufactured by Esaote Biomedica.
'The Esaote Group is a global leader in research, production and marketing of medical diagnostic equipment and related services focused on solving the medical needs of our customers worldwide. With over 16% of its employees actively engaged in Research & Development, Esaote is pursuing new diagnostic technologies to be introduced in international healthcare markets.'

| Ultrasound Safety | |
| |
|
The main advantage of ultrasound is that certain structures can be observed without using radiation. However, ultrasound is energy and there are ultrasound safety regulations, because two bioeffects of ultrasound are heat and cavitation. Ultrasound is a mechanical energy in which a pressure wave travels through tissue. Reflection and scattering back to the transducer are used to form the image. As sound energy is transmitted through the tissue, some energy is reflected and some power is absorbed.
Possible physical effects with ultrasound:

|
The ultrasound safety is based on two indices, the mechanical index (MI) and the thermal index (TI). The WFUMB guidelines state that ultrasound that produces temperature rises of less than 1.5°C may be used without reservation. They also state that ultrasonic exposure causing temperature rises of greater than 4°C for over 5 min should be considered potentially hazardous. This leaves a wide range of temperature increases which are within the capability of diagnostic ultrasound equipment to produce and for which no time limits are recommended. However, it has not been determined that medical ultrasound causes any adverse reaction or deleterious effect.
The American Institute of Ultrasound in Medicine states that as of 1982, no independently confirmed significant biologic effects had been observed in mammalian tissue below (medical usage) 100mW/cm2.

| Urologic Ultrasound | |
| |
|
Urologic ultrasound includes the examination of the kidneys, renal vessels, urinary tract, bladder, prostate, and scrotum.
Usual gray scale ultrasound equipment and standard probes are sufficient to examine the kidney parenchyma and renal pelvis, the urinary tract and bladder. Doppler ultrasound is a useful adjunct to kidney ultrasound. High ultrasound system performance is desirable to show the arterial system, because advanced power Doppler is significantly more sensitive to blood flow than standard color Doppler.
Transurethral sonography may be used to examine the bladder and urethra.
Transrectal sonography is used to scan and treat the prostate e.g., with brachytherapy or high intensity focused ultrasound. Very small probes are used for these applications. Reflux sonography is especially used in pediatric ultrasound.
