A new device and a geometric algorithm facilitate consistent insertion of a needle tip into nonpalpable breast lesions on a single attempt. With the breast compressed by dual grid plates, two oblique exposures are taken. Three intersecting planes through the lesion referenced to the grid markings permit easy determination of the lesion coordinates. In initial trials for preoperative breast lesion localization in 11 patients, the needle tip was within the lesion in nine patients and was within 0.5 cm of the lesion in two patients. The results indicate that this system is very useful for accurate localization and needle aspiration of breast lesions.
一种新设备和一种几何算法有助于单次尝试就将针尖一致地插入不可触及的乳腺病变中。在双格栅板对乳房进行压迫的情况下，进行两次倾斜投照。通过参照格栅标记穿过病变的三个相交平面可轻松确定病变坐标。在针对11例患者进行的术前乳腺病变定位的初步试验中，9例患者的针尖位于病变内，2例患者的针尖位于距病变0.5厘米范围内。结果表明，该系统对于乳腺病变的精确定位和针吸活检非常有用。
