INTRODUCTION
About the model “prosound F75”
The prosound F75 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.
1)

2-2.Abdominal Measurement Functional Outline
2-2-2. 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.

Measurements of abdominal region arterial blood flow
With tracing or pointing the Doppler waveforms (pulse method) of arterial blood flows in the abdominal region, it
is demanded of the blood flow measurement data (PSV, EDV, and S/D of bloodstream).
As measurement menu, A-Ao, CA, CHA, SA, SMA, IMA, CIA, Renal-A, HA and Prandial SMA are arranged.
In the CIA, HA and Renal-A, these can be switched for performing the Right/Left switching on the touch panel.
Also, Prandial SMA enables you to perform the changeover from before eating to after eating by using Pre/Post on
the touch panel.
For each blood flow measurement, there are two measurement procedures (Trace or Caliper) available and they are
selected with the touch panel.
[Remark]
For the calculation of PI and RI, a systolic maximum blood flow rate (PSV) and an end-diastolic blood flow rate
(EDV)are used.
In addition, as for the index, there is a report that an end-diastolic minimum blood flow rate is used.
An end-diastolic blood flow rate and an end-diastolic minimum blood flow rate are not necessarily correlation with
each other. Therefore, when these measurements are carried out, move the time phase of EDV to the end-diastolic
or the minimum blood flow velocity point with manual operation.
The PI and RI are calculated with the blood flow rates at these points.
1) Operation using Doppler trace
<Operation method>
The following procedure applies to the CA Dop. Trace method.
(1)
Display the blood flow Doppler waveform of a celiac artery.
(2)
Select the CA, and select the Flow Trace on the touch panel.
→The line cursor (vertical line) is displayed. (The + mark is
displayed in the case of the Manual Trace method.)
S
D
(3)
Using the Dop Trace method, trace the blood flow Doppler waveform.
PI, RI, S/D, etc. are calculated, and a line cursor is automatically
displayed at the rising point in the waveform in addition to the line
cursors accompanied by the letters "S" and "D".
[Remark]
Adjust the line cursors accompanied by the letters "S" and "D" and the rising point in the waveform using ENTER
and the trackball.
"S": Peak Systolic Velocity point "D": End Diastolic Velocity point
[Remark]
In the Dop Trace method, the operation method of Auto Trace differs from that of Manual Trace.
For details of the Manual Trace method and the operation method when multiple heartbeats are set, refer to Section
1-9-3-11. "Pulsatility Index (PI)".
