Abstract
Görüntü birleştirme medikal alanda tamamlayıcı yönüyle ve
teşhis ve tedavi planlama gibi uygulamalarda kullanılmasıyla
dikkat çekmektedir. Bu çalışmada 8 adet küçük hücre dışı
akciğer kanserli hastanın positron emisyon tomografi (PET)
ve bilgisayarlı tomografi (BT) görüntüleri önce çakıştırılmış
sonra dalgacık ve temel bileşen analizi metotlarıyla
birleştirilmiştir. Karşılıklı bilgi ve eğitimli gözle kıyaslama
sonucunda dalgacık daha başarılı bulunmuştur.
Image fusion attracts attention in medical field due to complementary behavior and application such as diagnosis and treatment planning. In this study, first positron emission tomography (PET) and computed tomography (CT) images coming from 8 nonsmall cell lung cancer were registered then wavelet and principal component analysis methods were applied to fuse images. According to mutual information metric and nuclear medicine expert wavelet method gave better results when compared to PCA.
