Various methods and systems are provided for displaying to an operator an attenuation map of a filter relative to a current location of an anatomical feature of a subject; and in response to the anatomical feature being within a region of the attenuation map, prompting an operator to reposition the subject. In this way, centering of the anatomical feature relative to an attenuation system may be facilitated for improved image quality.

Methods and systems for beam attenuation

A method for displaying medical image data. The method includes digitally combining 3D volume visualizations to form a plurality of four-dimensional (4D) volume visualizations representing the 3D volume visualizations over a period of time. The plurality of 4D volume visualizations include first and second 4D volume visualizations. The first 4D volume visualization including the entirety of the common region during a first time period, and the second 4D volume visualization including the entirety of the common region during a different second time period. The method also includes digitally combining the first and second 4D volume visualizations by digitally processing the first and second 4D volume visualizations to generate a modified 4D volume visualization of the entirety of the common region.

Method and system for generating a modified 4D volume visualization

Methods and systems for displaying medical images are provided. The method includes performing three-dimensional (3D) volume visualization on a plurality of two-dimensional (2D) images acquired continuously. The method further includes combining the 3D volume visualizations to form a plurality of four-dimensional (4D) volumes representing the 3D volume visualizations over a period of time and displaying at least one 4D volume.

Method and system for displaying a cine loop formed from combined 4D volumes

A CT system includes a scintillator array having a first length in an axial direction of the CT system, the scintillator array includes a plurality of scintillator cells along the first length. The CT system includes a controller configured to repeatedly position a subject fore and aft along the axial direction and over a second length of the CT system, the second length greater than the first length, energize an x-ray source to emit x-rays toward the subject while the subject is being repeatedly positioned, and obtain non-uniform projection data of the subject from the scintillator array, the non-uniform projection data comprising the x-rays received from the x-ray source while the subject is repeatedly positioned. The CT system includes a computer programmed to reconstruct a plurality of temporally non-uniformly spaced images from the non-uniform projection data, interpolate the plurality of non-uniform images to form a plurality of temporally uniform images, and apply a perfusion map generation process to the plurality of temporally uniform images.

Method of CT perfusion imaging and apparatus for implementing same

A method for retrospective internal gating is provided. The method includes scanning a patient to obtain projection data, generating images from the projection data, generating a signal representing information regarding a physiological cycle of an object within the patient, specifying at least one target phase based on which the images can be sorted, and sorting the images based on the target phase within a cycle of motion of the object to generate at least one series of images.
