Abstract. This paper aims to two main goals, first goal is to achieve the
characterization of quality control of ultrasound scanners based on the potential
image metrics. On the other hand, the most effective goal is how to classify
ultrasound scanners based on image metrics to evaluate performance of ultra-
sound transducer. The authors utilize the metrics to give information about the
spatial arrangement of the gray levels in the specific interest region. The exe-
cution of ultrasound images metric based on a set of 19 metrics (i.e. contrast,
gradient and Laplacian). This set reflects quality control of ultrasound scanners.
The wok of this paper based on the best 6 metrics from 19 metrics which
extracted from linear discriminative analysis (LDA). The classification methods
used for minimum numbers of metrics are fused using support vector machine
(SVM) and the highest classification method is back propagation neural network
(BPNN) classifiers to get the main target of paper. Finally, the results show that
objective performance evaluation of ultrasound transducer accuracy was 100%
by using back propagation neural network classifier.

1 Introduction
Quality control is most invaluable to estimate image quality and machine precision
both during the presentation of a modern technology and with regard to performance
constancy of over time. Quality control of various ultrasound units is performed on the
basis of detection of focal lesions against background tissue because of high spatial
resolution and contrast sensitivity requirements [1]. Spatial resolution is defined in
