Patent

CA 2748234

A method of producing a denoised medical image at a specified resolution, comprising: a) denoising an original medical image acquired at a resolution higher than the specified resolution; and b) reducing the resolution of the image, after denoising, to the specified resolution, using a nonlinear resolution reduction procedure that preserves more fine detail in the image than a linear resolution reduction procedure would.

L'invention concerne un procédé de production d'une image médicale dont le bruit a été éliminé à une résolution spécifiée, consistant à : a) éliminer le bruit d'une image médicale originale acquise à une résolution plus élevée que la résolution spécifiée ; et b) réduire la résolution de l'image, après élimination du bruit, à la résolution spécifiée, en utilisant un processus de réduction de résolution non linéaire qui préserve dans l'image des détails plus précis que ne le ferait un processus de réduction de résolution linéaire.
