Early, accurate and efficient screening of tumour will go a long way to improve the life expectancy and quality of life. Microwave holographic technique uses nonionising radiation which has the potential to screen patients for tumour at low cost. It offers high contrast between healthy and malignant tissues and assists in forming image of the location and the extent of the malignant tissue. This technique exploits the advantages of holography without requiring the direct measurement which uses an expensive network analyser. This paper will investigate the use of an alternative microwave imaging technique using indirect holographic method. The use of continuous wave signal for imaging avoids the problems associated with pulsed systems. The use of two stage holographic technique requires recording of a holographic interference pattern as stage one and reconstruction of original image of the object as stage two. As a preliminary study, the transmitted microwave signal is bombarded on a suitable phantom and the scattered signals are measured. The significance of this technique is that it offers real time imaging possibility which can be used as intra operative imaging tool during the surgery to remove tumour.

PurposeTo expose engineering students to using modern technologies, such as multimedia packages, to learn, visualize and solve engineering problems, such as in mechanics dynamics.Design/methodology/approachA multimedia problem‐solving prototype package is developed to help students solve an engineering problem in a step‐by‐step approach. A learning architecture model for developing an interactive technology‐assisted problem solving (TAPS) package for visualizing engineering concepts has been discussed.FindingsThe learning model was found to be easy to follow and use and the engineering package can be designed in an easy and visually appealing format. The TAPS package implemented and described in this paper could support and provide students with a better understanding of the basic concepts in an engineering mechanics dynamics course in particular.Research limitations/implicationsThe evaluation of the TAPS package materials comprised mainly quantitative methods which provided validation of the package approach for the acquisition of procedural skills and related basic concepts. More work is necessary to employ qualitative approaches for more detailed analysis of usability of particular materials of the TAPS package.Originality/valueThe main originality of the paper can be seen from the development of the package that guides the student intelligently to solve the selected engineering problem. In addition, important user tools are also included which the user may need to use if necessary.
