Computed tomography CT plays an important role in oral and maxillofacial surgery. Computed tomography is superior to conventional radiography in the evaluation of maxillofacial region. The image quality has improved significantly in the more recent CT scanners enabling excellent depiction of the complex anatomy of the maxillofacial region. In CT scanning there is satisfactory images of facial planes, muscles, bone and soft tissue in this area. In the recent years, Cone Beam Computed Tomography CBCT has become one of the important diagnostic technologies especially in the maxillofacial area. Understanding of the basic physical principles in image acquisition and data processing of this technology is very important issue for clinical use of CT

Bilgisayarlı Tomografi Prensipleri ve Uygulamadaki Yenilikler

Öz

Bilgisayarlı tomografi BT , oral ve maksillofasiyal cerrahide çok önemli bir yere sahiptir. Maksillofasiyal bölgenin değerlendirilmesinde, geleneksel radyografilere oranla birçok avantaja sahiptir. Geliştirilen BT cihazları, kompleks maksillofasiyal bölge anatomisinin, yumuşak ve sert dokuların ayrıntılı şekilde görüntülemesine imkan vermektedir. Son yıllarda, konik ışınlı bilgisayarlı tomografi KIBT , medikal BT’lere alternatif olarak özellikle maksillofasiyal bölgede önemli bir tanısal görüntüleme teknolojisi olarak öne çıkmıştır. Klinik kullanımı için, BT teknolojinin görüntü elde etme ve veri işleme ile ilgili basit fizik prensiplerini bilmek önemli bir konudur

Anahtar Kelimeler
