6. ale The cell is in a computer controlled feedback loop and produces a digital readout Watts of power custom units or grams of force The choice of units Watts or grams is selected by front panel pushbuttons TEST SETUP Water as a Measurement Medium The measurements are to be performed in water because ultrasound propagation in water closely approximates that in tissues The ultrasonic attenuation in water can be taken as a lower limit on the attenuation that will be encountered in the body Large areas in the body can consist of low attenuating material such as urine and amniotic fluid The use of water prevents measurements in a more highly attenuating material such as liver equivalent gels from representing the highest possible intensities that might be encountered in the body Ultrasound propagation in water closely approximates human tissue and degassed water is the generally accepted test medium for ultrasound transducers see AIUM NEMA Standards Publication UL 1 1981 SAFETY STANDARD FOR DIAGNOSTIC ULTRASOUND EQUIPMENT Degassed Water Ultrasound Power measurement accuracy is affected if the water contains more than 5 10 PPM of air To degas boil distilled water for 30 minutes then seal the container tightly and place it in a refrigerator An alternate method of degassing water is to heat the water to the boiling point then pull a vacuum on it for five to ten minutes The degassed water storage container should be mad
7. e of glass or plastic Polystyrene containers should not be used since they allow oxygen to permeate and degrade the water quality Before testing pour water into tilted test tank with minimum amount of turbulence The test tank water surface will absorb oxygen therefore a change of degassed water is recommended before each test Water temperature affects accuracy so it is 2 recommended to use an ambient testing temperature of 24 0 3 0 C 75 2 5 4 F Sonic energy agitates the water surface through heating and scattering The time duration of each test should be limited to a few minutes Prolonged testing particularly at higher power levels will show visible signs of air bubbles on the transducer target and the absorbing rubber surface Transducer Wetting and Placement To avoid introducing air into the degassed water insert the transducer at a 45 angle then position so it is facing the target Verify that the transducer surface is uniformly wetted if not wipe the surface clean using your finger The transducer should be pointed toward and center positioned directly above the cone target Small measurement variations will occur due to placement of the transducer Try various positions above the target to minimize the magnitude of error due to positioning LAYOUT A Unit of BC Group International 1 On Zero Off Button Press to turn unit on or zero press and hold until OFF is displayed then release to turn off
