Make sure your hospital’s firewall software is configured correctly, thus blocking incoming
connection requests from Internet. Improper use of network connection may cause the virus
infections of system and eventually malfunction may occur.
2.5 Biological Safety
This product, as with all diagnostic ultrasound equipment, should be used only for valid reasons
and should be used both for the shortest period of time and at the lowest power settings necessary
(ALARA - As Low As Reasonably Achievable) to produce diagnostically acceptable images. The
AIUM offers the following guidelines:
Clinical Safety Quoted from AIUM
Approved March 26, 1997
Diagnostic ultrasound has been in use since the late 1950s. Given its known benefits and
recognized efficacy for medical diagnosis, including use during human pregnancy, the American
Institute of Ultrasound in Medicine herein addresses the clinical safety of such use:
There are no confirmed biological effects on patients or instrument operators caused by exposures
from present diagnostic ultrasound instruments. Although the possibility exists that such biological
effects may be identified in the future, current data indicate that the benefits to patients of the
prudent use of diagnostic ultrasound outweigh the risks, if any that may be present.
Heating: Elevating tissue temperature during obstetrical examinations creates medical concerns.
At the embryo development stage, the rise in temperature and the length of time exposed to heat
combine to determine potential detrimental effects. Exercise caution particularly during Doppler
exams. The Thermal Index (TI) provides a statistical estimate of the potential temperature
elevation (in centigrade) of tissue temperature. Three forms of TI are available: Soft Tissue
Thermal Index (TIS), Bone Thermal Index (TIB) and Cranial Bone Thermal Index (TIC).
Soft Tissue Thermal Index (TIS). Used when imaging soft tissue only, it provides an estimate of
potential temperature increase in soft tissue.
Bone Thermal Index (TIB). Used when bone is near the focus of the image as in the third trimester
