درجات لوبولاریته و ریزلوبولاریته
رادیولوژیست ها از یک شیوه غیر رسمی برای تعیین لوبولاریته و ریزلوبولاریته (لوبولاریته میکرو) توده استفاده می کنند. ب دو توده به تصویرکشیده شده در شکل 5 را در نظر می گیریم. توده اول دارای حرکات نوسانی عمیق و توده دوم دارای حرکات نوسانی سطحی می باشد.برای رسمی نمودن این وجه تمایز، از معیارهای مختلفی می توان استفاده نمود.

In current practice, radiol-ogists make a relatively subjective determination for many terms from the lexicon related tobreast cancer diagnosis. Lobulation and microlobulation of nodules are two importantfeatures in the ACR lexicon. We offer an approach for formalizing the distinction of thesefeatures and also formalize the description of intermediate cases between lobulated andmicrolobulated masses. In this paper it is shown that fuzzy logic can be an effective tool indealing with this kind of problem. The proposed formalization creates a basis for the nextthree steps: (i) extended verification with blinded comparison studies, (ii) the automaticextraction of the related primitives from the image, and (iii) the detection of lobulated andmicrolobulated masses based on these primitives. © 1997 Elsevier Science B.V.Keywords:Fuzzy logic; Feature formalization; Breast cancer; Image recognition; Neuralnetworks* Corresponding author.
