  1. Place gel inside the sheath.
  2. Insert the transducer into the sheath.
  3. Pull the sheath over the transducer and cable until the sheath is fully extended.
  4. Secure the sheath using the bands supplied with the sheath.
  5. Check for and eliminate bubbles between the face of the transducer and the sheath. If any bubbles are present between the face of the transducer and the sheath, the ultrasound image may be affected.
  6. Inspect the sheath to ensure there are no holes or tears.

Getting Started

System Components
The system consists of the following:

  • The VPS Rhythm® DLX system
  • The SP-L01 linear array probe and cable

See the VPS Rhythm® DLX Operator’s Manual for operating instructions and for connection of the ultrasound probe to the VPS Rhythm® DLX Device.
Statement of Accuracy
Distance Measurements: Accuracy of distance measurements is the greater of ± 2% or ± 2 mm. All measurements made by the ultrasound system assume an average sound velocity of 1540 m/s in soft tissue. As the ultrasound system can only measure what is displayed on the screen, the operator must be diligent in obtaining a good image. Measurements should not be used as the sole determinant of diagnosis and treatment but should always be combined with other clinical data. Various factors including the scanning technique, familiarity with placement of the calipers, and the tissues being imaged, affect the image quality and thus the measurement accuracy.
Color Doppler Display: By selecting the CFM mode, the image display will show different colors to indicate fluid flow toward or away from the probe, and different shades to indicate velocity. The color information displayed is a qualitative indication of fluid flow and direction. The SP-L01 probe is able to discriminate between positive and negative low flow rates of 5.5 cm/sec at the center of the scale, and show representative lightening of the color displayed as the flow rates increase, to a maximum scale value of ± 28.0 cm/sec.
⚠ WARNING
The experience and diligence of the operator in achieving a quality image are major factors in the accuracy of distance measurements. The operator must ensure that measurements are made only on suitable images to achieve accurate measurements.

Appendix D – Achieving ALARA

The acoustic power of diagnostic ultrasound and its possible effects on human tissue has been studied for many years. The acoustic power of ultrasound imaging transducers must be below specific limits that are established by international standards bodies as well as required by governmental regulatory controls. While modern ultrasound imaging transducers are well below the allowable limits, it is standard practice to abide by the principle to set the power and limit the use to “As Low As Reasonably Achievable” (ALARA). The concept is quite simple: keep the acoustic exposure at the lowest possible levels and use the shortest amount of time that is necessary to obtain the desired diagnostic image. As the acoustic power can only be set lower than the allowed limit, the combination of lowering the transmit power and reducing the exposure time will minimize any possible biological effects.
There are two output display indices (Thermal Index and Mechanical Index) that notify the user of the amount of energy that is being transmitted. The output display indices are updated based on the settings that the operator of the ultrasound system uses to optimize the image. By providing the indices, operators are informed of the values and can therefore adapt their procedure to better abide by ALARA.
ALARA Guidelines
ALARA places responsibility to lower the power from the maximum level on the operator. As was mentioned above, acoustic power can only be lowered from its maximum and the maximum is well below the allowable limit. How does the operator determine what power level to set? ALARA directs the operator to use the lowest possible acoustic power that still allows a diagnostic quality image to be obtained. Using a higher transmit frequency results in lower biological effects. Therefore, using the highest possible frequency that still allows the operator to see to the required depth would be applying ALARA correctly. The quality of the image is also determined by the receiver controls such as gain, intensity, and contrast. As receiver controls do not affect acoustic transmit power, it is always good practice to adjust the receiver controls before considering an increase in acoustic transmit power. ALARA also directs the operator to use the transducer for the minimum amount of time that is necessary to obtain the desired diagnostic-quality image.
Applying the ALARA Principle
Prior to starting the ultrasound scan, be sure to select the proper transducer for your application. The linear array transducer is used for small parts, close to the surface scanning, down to about 6 cm. The software opens with power set to a specific value and the pulse frequency set to the center value. However, as a higher pulse frequency creates less of a biological effect, increase the pulse frequency as high as possible while still allowing you to reach your target depth. Although this acoustic power setting is well below the allowable limits, the ALARA principle directs you to use the lowest possible power. Use the highest pulse frequency and lowest acoustic power while still enabling you to acquire the image that you need.
Scanning time should be kept to a minimum. However, do not shorten the session so much that a follow-up exam is necessary as this would only increase the overall exposure for the patient.
Display of Indices
The calculated Mechanical Index and Thermal Index can be viewed on the main display screen and can be monitored by the operator. By monitoring these displayed values as the acoustic power, depth, and frequency are adjusted, the operator can achieve the lowest possible values of the indices that still enables them to acquire the desired image. Proper ALARA principles direct you to move through the exam quickly and ensure that the indices are kept to a minimum. The resolution of displayed Mechanical and Thermal Indices is 0.1. Displayed values are relative values based on acoustic power testing and change in frequency, transmit power, and focal depth. Mechanical and Thermal indices are calculated values. They cannot be measured and as such should be only used as input to properly practice the ALARA principles of keeping the acoustic power exposure to a minimum.
Thermal Index Display
There are three thermal indices. The TIB informs the user of potential heating near the focus after the ultrasound has transitioned through fluid or soft tissue. TIC informs the user of potential heating of bone at or near the surface. TIS is used to indicate any heating effect in soft homogenous tissue. If the ultrasound device is not capable of exceeding a thermal index of 1.0 in any mode, then the thermal index is not displayed.
Adjusting Image Controls to Minimize the Indices
As acoustic power is minimized you will see the Mechanical and Thermal indices values changing. When using color mode with standard 2D mode, the system will display the Indices for the color or 2D, whichever is greater. Biological effects are also dependent on pulse frequency. Higher pulse frequencies have lower biological effects. Therefore, use the highest pulse frequency that still allows you to obtain the desired image.
As displayed depth is changed the transmit focal point and frame rate are adjusted automatically for the user. If the new depth and focal point affect the indices, the user will see the displayed indices change.

Guidance and manufacturer’s declaration – electromagnetic immunity

Interson’s Ultrasound Probes are intended for use in the electromagnetic environment specified below. The customer or the user of the Interson Ultrasound Probe should ensure that it is used in such an environment.
IMMUNITY test| IEC 60601 TEST LEVEL| Compliance Level| Electromagnetic environment – guidance
Conducted RF IEC 61000-4-6| 0.15 – 80 MHz 3 Vrms & 6 Vrms 1 kHz| 0.15 – 80 MHz 3 Vrms & 6 Vrms 1 kHz| Portable and mobile RF communications equipment should be used no closer to any part of the product, including cables, than the recommended separation distance calculated from the equation applicable to the frequency of the transmitter.
Recommended separation distance:  = 1.2√
= 1.2√ for 80 MHz to 800 MHz
= 2.3√ for 800 MHz to 2.5 GHz
Radiated RF IEC 61000-4-3| 80 MHz to 6 GHz

Field strengths from fixed RF transmitters, as determined by an electromagnetic site survey a, should be less than the compliance level b in each frequency range.
Interference may occur in the vicinity of equipment marked with this symbol.
NOTE 1: At 80 MHz and 800 MHz, the higher frequency range applies.
NOTE 2: These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection from structures, objects and people.
a. The ISM (industrial, scientific, and medical) bands between 150 kHz and 80 MHz are 66.765 MHz to 6.795 MHz; 13.553 MHz to 13.567 MHz; 26.957 MHz to 27.283 MHz; and 40.66 MHz to 40.70 MHz.
b. The compliance levels in the ISM frequency bands between 150 kHz and 80 MHz and in the frequency range 80 MHz to 2.5 GHz are intended to decrease the likelihood that mobile/portable communications equipment could cause interference if it is inadvertently brought into patient areas. For this reason, an additional factor of 10/3 has been incorporated into the formulae used in calculating the recommended separation distance for transmitters in these frequency ranges.
c. Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and land mobile radios, amateur radios, AM and FM radio broadcast and TV broadcast cannot be predicted theoretically with accuracy. To assess the electromagnetic environment due to fixed RF transmitters, an electromagnetic site survey should be considered. If the measured field strength in the location in which the Ultrasound Probe is used exceeds the applicable RF compliance level above, the Ultrasound Probe should be observed to verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as re-orienting or relocating the Ultrasound Probe.
d. Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 1 V/m.
