Meme lezyonu segmentasyonunda EM ve K-mean algoritmaları performansını arttırma

Özet Amaçlar: Meme kanseri, kadınlarda en yaygın görülen kanser türüdür ve kanserle ilgili ölümlerin büyük bir bölümünü oluşturur. Diğer kanser türlerinde olduğu gibi, meme kanserinin önlenmesi ve erken teşhisi gün geçtikçe daha da önem kazanmaktadır. Bu amaçla, yapay zeka tabanlı karar destek sistemleri son yıllarda popüler hale gelmektedir. Bu çalışmada, manyetik rezonans görüntüleme (MRG) protokolü ile çekilen görüntülerde meme lezyonlarını tespit etmek için otomatik bir meme lezyonu segmentasyon süreci önerilmektedir. Yöntemler: İki en popüler segmentasyon yöntemi olan beklenti maksimizasyonu (EM) ve K-ortalama algoritmaları, meme lezyonlarının bölgesini belirlemek için kullanılmıştır. Ayrıca, EM ve K-ortalama yöntemlerinden sonra süper piksel tabanlı bulanık C-ortalama (SPFCM) algoritması, lezyon segmentasyon performansını artırmak için uygulanmıştır. Sonuçlar: Önerilen yöntemler, yazarlar tarafından etik izinle oluşturulan özel bir veritabanında değerlendirilmiştir. Kullanılan yöntemlerin performansları, bir radyolog tarafından belirlenen lezyon alanlarıyla (gerçek veri) otomatik segmentasyon algoritmalarıyla elde edilen alanların karşılaştırılmasıyla analiz edilmiştir. Sonuç: Performans karşılaştırması için Dice katsayısı, Jaccard endeksi (JI) ve eğri altı alan (AUC) ölçüleri hesaplanmıştır. Simülasyon sonuçlarına göre, EM, K-ortalama, EM+SPFCM ve K-ortalama+SPFCM yöntemleri meme MRG veritabanında iyi segmentasyon performansı sağlamaktadır. En iyi segmentasyon sonuçları EM+SPFCM hibrit yöntemi kullanılarak elde edilmektedir.

Improving the performance of EM and K-means algorithms for breast lesion segmentation

Abstract Aims: Breast cancer is the most common type of cancer in women and accounts for a large portion of cancer-related deaths. As in the other types of cancer, the prevention and early diagnosis of breast cancer gain importance day after day. For this purpose, the artificial intelligence-based decision support systems become popular in recent years. In this study, an automatic breast lesion segmentation process is proposed to detect breast lesions in the images taken with magnetic resonance imaging (MRI) protocol. Methods: Two most popular segmentation methods: expectation maximization (EM) and K-means algorithms are used to determine the region of breast lesions. Furthermore, superpixel based fuzzy C-means (SPFCM) algorithm is applied after EM and K-means methods to improve the lesion segmentation performance. Results: The proposed methods are evaluated on the private database constructed by the authors with ethical permission. The performances of the utilized methods are analyzed by comparing the lesion areas determined by a radiologist (ground-truth) and areas that are achieved by automatic segmentation algorithms. Conclusion: Dice coefficient, Jaccard index (JI), and area under curve (AUC) metrics are calculated for performance comparison. According to the simulation results, EM, K-means, EM+SPFCM, and K-means+SPFCM methods provides good segmentation performance on breast MRI database. The best segmentation results are obtained by using EM+SPFCM hybrid method.
