Download or read book Integration of CT PET Images for the Optimization of Radiotherapy Planning written by and published by . This book was released on 2001 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: A procedure is presented, based on the combined use of two different tomographic imaging modalities (PET and CT), aimed at the optimization of radiotherapy planning. The combined use of functional PET and anatomical CT studies allows a better definition of the tumor mass with respect to tile conventional CT based approach. The proposed procedure consists in: a) spatial registration of CT and PET studies; b) contour drawing based on the coincided observation of PET and CT. The set of contours thus obtained, defining optimized volumes of interest for radiotherapy, can be exported to the treatment planning system for designing the radiation beams geometry. The accuracy of the image registration was evaluated by phantom studies and found to be less than 2 pixels in plane and less than slice thickness axially, with respect to CT. The application of the procedure to the case of a patient affected by pancreatic tumor is presented, showing how the treatment planning can be improved by multimodal CT/PET information.

Download or read book Optimization of Reconstruction Methods and Injected Activity for Whole Body 18F FDG PET CT Imaging written by Alexander Hart and published by . This book was released on 2021 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: [18F]Fluorodeoxyglucose ([18F]FDG) Positron Emission Tomography/Computed Tomography (PET/CT) imaging is a powerful tool in the diagnosis of cancer and subsequent treatment planning. New state-of-the-art PET/CT scanners have the capacity to generate images of superb quality. The new scanners feature detectors with increased sensitivity and a new generation of reconstruction algorithms that produce higher quality images than the scanners they are replacing. In addition to the scanner, the scan duration, amount of administered [18F]FDG activity, and the anatomy of the patients themselves are also determining factors of image quality. There is evidence suggesting that [18F]FDG PET image quality is significantly reduced for larger patients, jeopardizing lesion detection. Two possible solutions to this problem are to (i) increase injected activity or (ii) increase scan duration. Increasing scan duration is preferable but not always possible in a busy clinic. Increasing injected activity is necessary but a proper scaling regimen with patient size must be determined in order to achieve consistent image quality. The aim of the work presented in this thesis was to achieve higher quantification accuracy and consistent image quality for all patients scanned with [18F]FDG PET. Because quantitative PET/CT images require corrections for image degrading effects, for which attenuation correction is the main contributor and is performed based on CT images, the first step in this project was to develop software tools to automate the analysis of phantom images for CT quality assurance. The next step was to optimize the reconstruction parameters for whole body [18F]FDG PET based on a phantom experiment. Finally, a retrospective study was conducted using patient [18F]FDG PET images to characterize the relationship between patient anatomical characteristics and image quality. This work concludes by suggesting optimized reconstruction parameters and a scaling regimen for injected [18F]FDG activity. With the implementation of these recommendations it can be possible to obtain images with increased quantitative value while delivering less dose to patients and maintaining a uniform level of image quality between different patients.
