Paper Abstract

Multiple aspect thermography (MAT) is a kind of developmental thermography. MAT was designed in order to supplement the shortage of the number of coverage aspects in triple aspect thermography (TAT). TAT allows simultaneous display of numbers of thermograms on various selected aspects of the subject in CRT frame. This paper reports on MAT methodology and discusses some aspects of the problems and the special points of this technique. The data on the thermal images on the entire subject can be recorded in one revolution of the subject. After the measurement is completed all over the subject, thermograms of any selected aspects is composed in a CRT frame in multiple image arrangement by recalling the recorded thermal data using the multi-video processor. Strictly speaking, based on the thermography on the moving target in MAT, distortion and smoothing of the thermal pattern in MAT are essentially unavoidable. The shorter the frame time of the thermocamera is, the less the problems in MAT can be reduced. However, the problems in MAT are negligible under the usual condition for clinical application of MAT.
