By applying pseuso-color technique to ultrasonic NDT,the pseudo-color display of ultrasonic NDT results is realized,with improved readability of NDT results and dis-play ability of defects.

The challenge of ultrasonic nondestructive testing (NDT) focuses on fast , effective and accurate obtaining position , form and size of defect and guaranteeing the test result high reliably and sensitivity.
Korolev, the oldest worker of the Central Research Institute for Heavy Machinery (TsNIITMASh), has told about some episodes on the initial stages of the ultrasonic NDT development.
Today, the TOFD procedure is used for operational inspections or quality control of structures during production instead of routine radiography and ultrasonic NDT procedures [1].
A novel method of time-frequency analysis, wavelet-packet atomic decomposition based on the matching-pursuit (MP) algorithm, is proposed for improvement of ultrasonic flaw detection during ultrasonic NDT.
Human eyes are far more sensitive to variation in color than in grey-scales,but presently most of the dis play of ultrasonic NDT results are done in grey-scale.By applying pseuso-color technique to ultrasonic NDT,the pseudo-color display of ultrasonic NDT results is realized,with improved readability of NDT results and dis-play ability of defects.
