INTRODUCTION

About the model “SSD-α10” The SSD-α10 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)

PRECAUTIONS Concerning the Use/Management of the SSD-α10 •

Do not disassemble, repair or remodel this equipment or optional features without our consent. NOTE: Disassemble means to remove the parts or options from the equipment

using tools. NOTE: Remodel means to install or connect unauthorized parts or equipment

including the power cord. •

Assembly of the equipment or optional accessories shall be performed by a third party certified by us. Please contact one of our offices listed on back cover. NOTE: Assemble means to install or connect parts or optional accessories in/to the

device using tools.

2)

•

Transporting this equipment (via automobile/ship) shall be performed by a third party certified by the manufacturer. Please contact one of our offices listed on back cover.

•

Please conduct routine cleaning and inspection of the equipment. Refer to Chapter 5 of the Safety Instruction for details.

•

Ensure that the output level of the scan conforms to the required duration of diagnosis.

•

If any malfunction or abnormality is discovered during operation of the equipment, remove the probe from the patient immediately and discontinue use. If any abnormality is observed in the patient, provide proper care as quickly as possible. Refer to Chapter 4 of the Safety Instructions for more information on dealing with the equipment appropriately. If the malfunction is not listed in Chapter 4 of the Safety Instruction manual, contact one of our offices listed on back cover.

PRECAUTIONS for the SSD-α10 Installation This equipment is a electrical medical device that intended for use in hospitals and research facilities. The device should be installed in accordance with the following guidelines.

•

Install in accordance with Chapter 3 of the Safety Instructions.

•

Install in an environment that conforms to the operating environments indicated in section 2-2-2 of the Safety Instruction manual.

•

Install in an environment that ensures electromagnetic compatibility, in accordance with section 1-2-6 of the Safety Instruction manual, "Precautions Concerning the Maintenance of Electromagnetic Compatibility," and Item 1-3, "Guidelines for Electromagnetic compatibility." NOTE: The electromagnetic compatibility (EMC) is the ability of device to function

satisfactorily in its electromagnetic environment without introducing intolerable electromagnetic disturbance to anything in that environment.

Remark

For steady state blood flow. For arterial blood flow.

MN1-5207 Rev.19 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 instrument 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.

Select the Right of the Renal Volume on the touch panel. →

(3)

Press the + switch. →

(4)

Measure the Width using the transverse image.

Press the + switch. →

(5)

The + mark is displayed, so measure the Length using the longitudinal image.

Measure the A-P using the transverse image. Volume (Rt.Renal Vol.) is computed.

Press the →

switch.

Measurement is finalized.

Spleen measurement

This measurement is for obtaining the spleen index (SI = axb) from the major diameter (a) and the thickness (b) of the spleen.

<Operation method> (1)

Record a slice image of the spleen in the B mode.

(2)

Select the Spleen on the touch panel. → A + mark appears, so measure the major diameter a.

(3)

Press the + switch. → Measure the thickness b.

(4)

Press the switch. → Measurement is finalized.

SOL (Space Occupying Lesions) measurement

This is the measurement of the length of the three axes of a space-occupying lesion, such as a tumor, for calculating the volume of the lesion using an elliptical approximation. The same operation is used for both SOL1 and SOL2.

<Operation method> (1)

Record a slice image showing the SOL in the B mode.

(2)

Select the SOL1 on the touch panel. → A + mark appears, so measure the first axis.

(3)

Press the + switch. → Measure the second axis.

(4)

Press the + switch. → Measure the third axis.

(5)

Press the switch. → Measurement is finalized.
