Effect of Noise Adaptive Wavelet Filter on Diagnostic Performance in Stroke Perfusion

Inal, Tolga; Atac, Gokce Kaan; Telatar, Ziya (Amer Scientific Publishers, 2021)

Background: Computed tomography perfusion (CTP) images include more noise than routine clinic computed tomography (CT) images. Singular value decomposition based deconvolution algorithms are widely used for obtaining several ...
Noise reduction in CT perfusion images: a bilateral filter trial

İnal, Tolga; Telatar, Ziya; Ataç, Gökçe Kaan (Ieee, 2014)

Computed Tomography (CT) perfusion images are acquired in short time period and in order to lower patient radiation dose. Low x-ray photon flux and energy are preferred in such CT exposures. Obtaineclimages contain more ...
