<p>PROBLEM TO BE SOLVED: To a securely piercing route for piercing a bioptic needle for a biopsy and an injecting needle for injecting medicine to an examinee. SOLUTION: This tomographic apparatus is constituted to automatically and collectively display a guide line GL connecting both of the bioptic needle piercing point A and a tissue collecting point B of the examinee M, an intersection mark MP showing the intersection of the guide line GL and a CT tomographic image and angles AG1, AG2 and a length D making the criteria of the piercing direction/depth of the bioptic needle on a display monitor at the time of designating and inputting the point A and the point B on the screen of the monitor 16. Since what an operator should do is only piercing the bioptic needle to a depth shown by the length D along the guide line GL and the mark MP in a direction shown by the displayed angles AG1, AG2, he can speedily pierce the bioptic needle or the injection needle to the examinee along the secure piercing route.</p> |
