Introduction
About the model “ProSound α7”
The ProSound α7 is intended to be used by doctors and other qualified personnel in fracture
diagnostics and hemodynamic diagnostics.
However, this equipment is not designed to be used in ophthalmic ultrasound diagnosis, as its
sound intensity is not compliant with ophthalmic restrictions established by the FDA.
Only physicians and other qualified personnel should operate this equipment for diagnostic
purposes. Read section 1-1 of the Safety Instruction.

4-2.Abdominal Measurement Functional Outline
4-2-2. Items of Particular Note
For blood flow velocity measurement: When recording an arterial flow Doppler waveform (pulse method), if the
Doppler incident angle exceeds 60× the measurement error becomes large.
The measured values of the blood flow values obtained using this equipment are the absolute values displayed on
the observation monitor. They are controlled as positive and negative values for the purpose of calculating the arithmetic index.
If the display of each measured value in a report is set to “Average” in a preset, the positive and negative values are
added together and displayed as a mean value. Consequently, when performing multiple measurements of blood
flow on the blood flow waveform drawn using the color Doppler method as a guide, use identical recording conditions (forward and reverse flow directions) for all of the blood flow waveforms in order to correctly display each of
the arithmetic values arranged in the report.
