Setting Function/Description
#–# xx
Transducer Type Displays the name of the transducer cur-
rently connected to the Cypress. The frequency range
depends on the type of transducer attached to the Cypress
system.
Pwr x
Transmit Power Controls the maximum acoustic output of
the transducer. Settings range from 5% to 100% of maxi-
mum. Use the Transmit Power option on the [
menu to select.
H (High), M (Medium), or L (Low)
MI #.#
Mechanical Index MI is a relative indicator of the potential
for mechanical effects and is used to estimate the potential
for mechanical bioeffects.
The higher the index reading, the larger the potential. How-
ever, neither MI = 1.0, nor any other level, indicates that a
bioeffect is actually occurring. Do not be alarmed by the
reading, but use it to implement the
sonably Achievable) principle.
TIx #.#
Thermal Index TI is a relative indicator of temperature
increase. The selections are Soft Tissue (s), Bone (b), or
Cephalic (c).
TI monitors conditions that may lead to a temperature rise,
whether at the surface, within the tissue, or at the point
where the ultrasound is focusing on bone. Each Thermal
Index estimates temperature rise under certain assumptions.
Soft Tissue (TIs): Cardiac, first trimester fetal,
and Abdominal
Cranial Bone (TIc): Transcranial (bone near surface)
Bone (TIb): Second and third trimester fetal (bone near
focus)
Compress #
Compression or Dynamic Range Use the Main knob to
adjust the range.
The settings are: 1—9.
PProc #
Post Processing Indicates the currently selected post-pro-
cessing curve. There are 7 curves.
