A disposable eye piece system, including the eye piece and other disposable components, for a precision ultrasonic scanning apparatus is disclosed. The eye piece includes a fill port, a vent port and a drain port molded into the base of the eye piece. An RF Identification chip may be molded into the plastic base of the eye piece or, alternately into the conformable face seal of the eye piece. The components of a disposable eye piece system form an integrated disposable package that can be assembled, packaged, transported and used while maintaining the eye piece and saline solution in a sterile condition. The protective shipping container 1) protects the eye piece from damage, human contact and exposure to ambient air during shipping and storage and 2) allows the scanning physician or technician to attach the eye piece to the scanning machine without compromising the sterile condition of the eye piece.

The invention provides a large flat plate current gathering resistance measurement device and method applied to breast cancer. The large flat plate current gathering resistance measurement device comprises an upper current gathering electrode array and a lower current gathering electrode array, which are in parallel arranged up and down and have the same upper and lower surfaces, wherein electrode regions of the upper current gathering electrode array and the lower current gathering electrode array are semi-circles with the diameter of 160mm; electrodes are arranged according to a honeycomb; the outer diameter of the electrodes is 4.5mm and the distance between the electrodes is 1mm; 392 electrodes are distributed in each electrode region; the upper current gathering electrode array and the lower current gathering electrode array can rotate for 360 degrees and breasts can be measured at any angle; when the upper current gathering electrode array and the lower current gathering electrode array are used for measuring, a partition measurement manner is adopted; each 7 electrodes in the 392 electrodes form a region group; each electrode occupies a small region; the 7 electrodes form one region group; the electrodes are triggered from a certain small region, span across two small regions along the vertical direction of an edge, turn leftward or rightward for 60 degrees and then span across one small region so as to reach the same group of electrodes; the electrodes of the same small group are measured simultaneously for each time until all the electrodes are detected. According to the large flat plate current gathering resistance measurement device and the method provided by the invention, the sensitivity of disturbance regions in breast tissues of the electrodes can be improved.
