Notes to current ways of development in computed tomography imaging techniquesReview article
- Klinika zobrazovacích metod LF UK a FN, Plzeň
The article is presentin current ways of the development of the scannng techniques in computed tomography. The following methods are mentioned: tin filtration of the spektra, scanning with the separate pulmonary and aortic arterial phase imaging, low-dose children imaging without sedation or anaesthesia, addaptive application of the contrast materiál with the possibilities of the dose reduction, novel trends in materiál analysis a the advent of the deep learning based methods and other artificial intelligence approaches in diagnostic.
Keywords: techniques of CT scanning, low-dose CT imaging, contrast material application, image analysis, DECT
