ABSTRACT
Objective To evaluate the importance of factors affecting efficiency of image display quality of realtime three-dimensional echocardiography (RT-3DE) and establish an optimized method for RT-3DE examination and image processing in children. Methods Based on corresponding cardiac acoustic characteristics in children, 87 healthy children (46 boys, 41 girls, mean 36.2 ± 44.2 months) were selected. Three aspects of seven factors were selected, including acquisition windows, gain, compress, post process, smoothing, frequency fusion and 3D vision for RT-3DE examination and analysis using orthogonal test design method. The principal effectiveness analysis of orthngonal test design method and its table L_(18)3~7 were used. The efficiency rate of 3D image display quality was used as the inspection index for orthogonal test. Results According to the average deviation orders of the seven factors, the maximal average deviation was gain. The aspects with maximal average deviation of each factor were at via-subcostal and via-apical acoustic windows, 90 of gain, 60 of compress, E of post process, 5 of smoothing, F3 of frequency fusion and A to B of 3D vision, respectively. Conclusions The optimized method for RT-3DE examination and image processing could be achieved by setting acquisition windows, gain, compress, post process, etc. It is helpful to promote clinical application of RT-3DE and benefits the design of multi-parameter presetting of ultrasound system to optimize RT-3DE examination in children.
