Summary of "Dosimetric Evaluation of 4D-CBCT Reconstructed by Simultaneous Motion Estimation and Image Reconstruction (SMEIR) for Carbon Ion Therapy of Lung Cancer."

Motion management is critical for the efficacy of carbon ion therapy for moving targets such as lung tumors. We evaluated the feasibility of using 4D-CBCT reconstructed by Simultaneous Motion Estimation and Image Reconstruction (SMEIR) for dose calculation and accumulation in carbon ion treatment of lung cancer.

4D cone beam computed tomography (CBCT) images of the thorax and abdomen can have reduced quality due to the limited number of projections per respiratory bin used in gated image reconstruction. In th...

MR-PET head motion correction based on co-registration of multicontrast MR images.

Head motion is a major source of image artefacts in neuroimaging studies and can lead to degradation of the quantitative accuracy of reconstructed PET images. Simultaneous magnetic resonance-positron ...

Joint cardiac and respiratory motion estimation for motion-corrected cardiac PET-MR.

Respiratory and cardiac motion can strongly impair cardiac PET image quality and tracer uptake quantification. Standard gating techniques can minimize these motion artefacts but suffer from low signal...

Medical and Biotech [MESH] Definitions

A method of delineating blood vessels by subtracting a tissue background image from an image of tissue plus intravascular contrast material that attenuates the X-ray photons. The background image is determined from a digitized image taken a few moments before injection of the contrast material. The resulting angiogram is a high-contrast image of the vessel. This subtraction technique allows extraction of a high-intensity signal from the superimposed background information. The image is thus the result of the differential absorption of X-rays by different tissues.

The simultaneous, or near simultaneous, transference of heart and lungs from one human or animal to another.

Timing the acquisition of imaging data to specific points in the cardiac cycle to minimize image blurring and other motion artifacts.

A film or video wholly or partially created by photographing drawings, sculptures, or other inanimate things in sequence to create the illusion of motion. Animations are also generated by computers. (From Moving Image Materials: Genre Terms, 1988)

Work consisting of untitled raw motion picture and video footage which has not been edited or assembled into a finished work. (From: Moving Image Materials: Genre Terms, 1988)
