Abstract
The present study evaluated the performance of the Ultrasound (US) and Doppler devices. The methodology was based on the recommendations of the American Association of Medical Physics (AAPM). The study used an image simulator phantom manufactured by Sun Nuclear/Gammex (model 403). The performance evaluation was applied for B-mode and Doppler. The study analyzed 182 devices with 546 transducers from different models and manufacturers. The evaluation parameters were: a) spatial resolution; b) depth of view c) image contrast; d) visualization of anechoic objects; d) velocity; e) sensitivity for (Doppler Mode); and f) artifacts in the images. The evaluation indicated that 43,95% of the probes showed some type of non-compliance, directly affecting the accuracy of the medical diagnosis. The present investigation indicates the need to carry out image quality evaluation to verify the degradation of the probes to minimizing possible errors in diagnostic imaging due to inadequate performance of the US equipments.
