z Essential performance of this system
• Free from noise on a waveform or artefacts or distortion in an image or error of a displayed numerical value which cannot be at-
tributed to a physiological effect and which may alter the diagnosis.
• Free from the display of incorrect numerical values associated with the diagnosis to be performed .
• Free from the display of incorrect safety-related indications .
• Free from the production of unintended or excessive ultrasound output .
• Free from the production of unintended or excessive TRANSDUCER ASSEMBLY surface temperature .
Notice1: "artifact" means "noise" that generates acoustically .
Notice2: "incorrect" in the sense that the displayed value differs from what is calculated (having been altered during
data transfer), or the calculation itself is not correct .
