Abstract: Devices and methods for embedding a standard dose checker feature within existing CT systems by obtaining and analyzing information from the existing CT system, detecting a radiation parameter value therefrom, comparing the detected radiation parameter with a predetermined threshold, and generating an operation-signal to affect the operation of the CT system based on the comparison between the detected radiation parameter and the predetermined threshold and the state of the CT system.

Abstract: 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.

Abstract: A method for generating a three-dimensional (3D) low-resolution image from a 3D high-resolution medical image. The 3D high-resolution medical image is a plurality of 2D images having an axial resolution in an axial direction in which the plurality of 2D images were acquired, the method including decomposing the plurality of 2D images generating a plurality of transformed data sets, wherein the transformed data sets corresponds to one of the plurality of 2D images; weighting each pixel in the transformed data sets lo generate a plurality of weighted transformed data sets; combining the plurality of weighted transformed data into a single new transformed data set; and generating a 3D low-resolution image, having a first resolution in the axial direction from each of the single new transformed data sets, wherein the first resolution in the axial direction of the 3D low-resolution image is lower than or equal to the axial resolution.
