Important Information - Please Read Before Use
The ALARA principle ALARA “as low as reasonably achievable” is the guiding principle for the use of diagnostic ultrasound. Qualified medical professionals, using good judgement and insight, determine the exposure that is as low as reasonably achievable. There are no sufficient rules to determine the correct response to every situation. Therefore it is the responsibility of the physician to keep exposure low, bioeffects minimal and images diagnostic. A thorough knowledge of the imaging modes, transducer capability, system setup, and scanning technique is necessary. The imaging mode determines the nature of the ultrasound beam. Transducer capability depends upon transducer frequency, penetration, resolution, and field of view. It is the scanning technique of the qualified ultrasound user along with patient variability that determine the system setting throughout the examination. There are variables that affect the way the physician implements the ALARA principle. These variables include body size, location of the bone relative to the focal point, attenuation in the body, and ultrasound exposure time. Exposure time is an especially useful variable, because it can be controlled by the physician. The ability to limit the exposure over time supports the ALARA principle.
Applying ALARA The system imaging mode selected by the physician is determined by the information required. 2D and 3D imaging provide anatomical information; color flow mode imaging provides information about the velocity of the Doppler signal over time at a given anatomical location; power flow mode imaging provides information about the detectable blood flow using the energy or amplitude strength of the Doppler signal over time at a given anatomical location. Understanding the nature of the imaging mode being used allows the trained physician to apply the ALARA principle. Prudent use of ultrasound implies that the patient exposure to ultrasound is limited to the lowest output for the shortest time necessary to achieve acceptable diagnostic results. The physician uses the system controls to adjust image quality and ultrasound output. The ultrasound center will not exceed an MI (mechanical index) of 1.0, or an ISPTA3 (the derated spatial peak temporal average intensity) of 720 mW/cm2 in any mode. In addition, the ultrasound center will not exceed a TI (thermal index) of 1.0 in any mode.
