Radiation Dose Reduction in Thorax CT

Bilgisayarlı Tomografi X-ışınlarıyla çalışan ve günümüzde kullanımı giderek artan bir yöntemdir. Kanser riskini azaltmak amacıyla hastaların maruz kaldığı X-ışın dozunu azaltmaya yönelik çalışmalar devam etmektedir. Amaç mümkün olan en düşük dozla en etkin görüntüyü elde etmektir. Bu makalede erişkinlerde BT radyasyon dozunu azaltmanın önemi ve yöntemleri sunulmaktadır.

Toraks Bilgisayarlı Tomografide Radyasyon Doz Azaltımı

Computerized Tomography is a method of working with X-rays and is increasing in application day by day. Scientists continue to conduct studies by reducing the dose of X-ray that patients are exposed to in order to reduce the cancer risk. The aim is to get the most effective image by the most minimal dose. In this review, the importance of CT radiation dose reduction and the methods in adults are presented.
