Clinical application of a real time linear array scanner for breast diseases was proven to have several advantages,
in comparison with a mechanical scan which has been used hitherto;
1) Diagnostic accuracy was satisfactory for practical use (84% for cancer and 81 % for benign diseases).
2) Echo images obtained by the real time scanner were of essentially the same quality in the contour, margin, internal echo and bottom echo of a tumor.
3) The real time scanner seemed to be very useful for clinical practice and also for a mass-screening, because of its easy and time-saving manipulation, its wide range of continuous tomography, its minimum image deformation caused by breath movements.
