<p>A guide plate (10) for inserting, into a body, instruments, such as needles (306), used for medical purposes, comprising a plurality of openings for receiving an instrument; for each of the openings, a sensor arrangement (201; 210, 212) for detecting presence of an instrument when an instrument is received in an opening; and reporting apparatus for reporting sensing of an instrument by each respective sensor arrangement. An imaging system (309), including a display (307) for displaying an image of a portion of the body, such as the prostate (321), into which instruments are inserted. The imaging system (309) superimposes on the image an array (Fig. 3A) corresponding to openings in the guide plate. A signal transmission means (314, 315, 316) responsive to reports from respective reporting apparatus transmits an output of the reporting apparatus to the imaging system (309). A display modification arrangement responsive to signals from the signal transmission means (314, 315, 316) modifies elements of the array to indicate an instrument has been inserted.</p> |
