OB examination, it provides an estimate of potential temperature increase in the bone or adjacent
soft tissue.
Cranial Bone Thermal Index (TIC). Used when bone is near the skin surface as in transcranial
examination, it provides an estimate of potential temperature increase in the bone or adjacent soft
tissue.
Cavitations: Cavitations may occur when sound passes through an area that contains a cavity,
such as a gas bubble or air pocket (in the lung or intestine, for example). During the process of
cavitations, the sound wave may cause the bubble to contract or resonate. This oscillation may
cause the bubbles to explode and damage the tissue. The Mechanical Index (MI) has been
created to help users accurately evaluate the likelihood of cavitations and the related adverse
effects.
MI recognizes the importance of non-thermal processes, cavitations in particular, and the Index is
an attempt to indicate the probability that they might occur within the tissue.
2.6 Scanning Patients and Education
The Track-3 or IEC60601-2-37 output display standard allows users to share the responsibility for
the safe use of this ultrasound system. Follow these usage guidelines for safe operation:
In order to maintain proper cleanliness of the probes, always clean them between patients.
Always use a disinfected sheath on all EV/ER probes during every exam.
Continuously move the probe, rather than staying in a single spot, to avoid elevated
temperatures in one part of the patient’s body.
Move probe away from the patient when not actively scanning.
Understand the meaning of the TI, TIS, TIB, TIC and MI output display, as well as the
relationship between these parameters and the thermal/cavitation bioeffect to the tissue.
Expose the patient to only the very lowest practical transmit power levels for the shortest
possible time to achieve a satisfactory diagnosis (ALARA - As Low As Reasonably Achievable).
2.6.1 Safe Scanning Guidelines
Ultrasound should only be used for medical diagnosis and only by trained medical personnel.
