Bilgisayarlı tomografi, x-ışınlarından faydalanılarak bir yapının iç ve dış geometrik verisinin detaylı bir şekilde elde edilebildiği bir tarama teknolojisidir. Bu teknoloji, tıp alanında hastalıkların teşhisinde görüntüleme aracı olarak kullanıldığı gibi elde edilen kesit görüntüler çeşitli yazılımlar yardımıyla 3B modellere dönüştürülebilmektedir. Bilgisayarlı tomografinin sağladığı ayrıcalıklar ve yöntemin tıp alanının dışındaki endüstriyel alanlarda tersine mühendislik, tahribatsız muayene gibi uygulamalar için de elverişli olması bu tarama teknolojisine ilgiyi daha da artırmıştır. Bu çalışmada bilgisayarlı tomografinin prensipleri, kullanılan yöntemler, ilgili terimler, parametreler ve birimler, bilgisayarlı tomografi makinelerinin jenerasyonları ve gelişimi, endüstriyel bilgisayarlı tomografi ve son yıllarda yapılan akademik çalışmalara yer verilmiştir.

Anahtar Kelimeler

Bilgisayarlı tomografi, 3B tarama, DICOM, artifakt, Hounsfield ölçeği.

THREE-DIMENSIONAL (3D) SCANNING WITH COMPUTERIZED TOMOGRAPHY

Öz

Computed tomography is a scanning technology with which it is possible to obtain detailed internal and external geometric data of a structure by using x-rays. This technology is used as an imaging tool in the diagnosis of diseases in the field of medicine, and the obtained cross-section images can be converted into 3D models with the help of various software. The privileges provided by computed tomography and also its convenience for applications such as reverse engineering and non-destructive testing in industrial areas outside the medical field have increased the popularity of this scanning technology. This study includes principles of computed tomography, methods used, related terms, parameters and units, generations and development of computed tomography machines, industrial computed tomography, and recent academic studies.

Anahtar Kelimeler

Computed tomography, 3D scanning, DICOM, artifact, Hounsfield unit.
