PP, LW, HV, SM, and PMPT have made great efforts to be trained in the ultra-sound guided breast surgery techniques, since they are the participating surgeons. They are also crucial in the inclusion of patients and the collection of all data of the randomised controlled trial. AHMTA and EB made contribution to the conception of the study and the design of the study, in particular for the technical part of ultrasonography. They teach the surgeons how to use the ultrasound. ML participated in the design of the quality of life assessment, constructed the questionnaires, and will carry out all quality of life interviews. ESMLK participated in the design of the study and carried out the statistical analysis, the interpretation of data and sample size calculations. HAHW participated inas the glass used as a component configuring the thick film resistor, mainly a glass containing lead oxide is used. The main reason of this is that the lead oxide-containing glass has a low softening point and has superior characteristics suitable for forming the thick film resistor, such as having a favorable fluidity, wettability with the conductive component, superior adhesiveness to a substrate, and a coefficient of thermal expansion suitable for ceramics, particularly an alumina substrate.
However, the lead component possesses a toxicity and is not desirable from the viewpoint of its effect on the human body and pollution. In order to deal with recent environmental problems, electronics products are required to comply with the Directive of WEEE (Waste Electrical and Electronic Equipment) and RoHS (Restriction of the Use
