To develop a device for specimen radiography of impalpable breast lesions with microcalcifications in order to perform compression-free radiography in two planes and to document the original orientation of the specimen on the radiographic film.
A curved plate with its radius equal to the film-focus-distance enables specimen radiography without compression and with minimizing artifacts induced by beam divergency. Adjustable markers can document the topographic orientation of the specimen on the radiographic film.
The presented specimen device for biplanar radiography avoids interfering compression artifacts for both radiologist and pathologist. Documenting the original topographic orientation of the specimen on the film helps to guide the surgeon in cases requiring further resection.
Biplanar specimen radiography without compression of the specimen measures the distance of microcalcifications to the margin of the resected tissue more accurately and thus provides a better basis for planning any necessary additional resection.
研发一种用于对不可触及的伴有微钙化的乳腺病变进行标本射线照相的设备,以便在两个平面上进行无压迫射线照相,并在射线照相胶片上记录标本的原始方向。
一个半径等于胶片-焦点距离的弯曲板可实现无压迫的标本射线照相,并将由射线发散引起的伪影降至最低。可调节标记物能够在射线照相胶片上记录标本的地形方向。
所展示的用于双平面射线照相的标本设备避免了对放射科医生和病理科医生造成干扰的压迫伪影。在胶片上记录标本的原始地形方向有助于在需要进一步切除的病例中指导外科医生。
对标本不进行压迫的双平面标本射线照相能更准确地测量微钙化与切除组织边缘的距离,从而为规划任何必要的额外切除提供更好的依据。
