Image-Based Computer-Assisted Radiation Therapy by Hidetaka Arimura

By Hidetaka Arimura

This publication offers a finished review of the cutting-edge computational intelligence examine and applied sciences in computer-assisted radiation remedy in accordance with photograph engineering. It additionally lines significant technical developments and learn findings within the box of image-based computer-assisted radiation therapy.

In high-precision radiation treatments, novel ways in photo engineering together with special effects, photograph processing, development acceptance, and computational anatomy play very important roles in enhancing the accuracy of radiation remedy and supporting selection making through radiation oncology execs, reminiscent of radiation oncologists, radiation technologists, and clinical physicists, in every one part of radiation therapy.

All the themes provided during this ebook expand realizing of the trendy scientific applied sciences and structures for image-based computer-assisted radiation treatment. for this reason this quantity will vastly profit not just radiation oncologists and radiologists but additionally radiation technologists, professors in clinical physics or engineering, and engineers concerned about the improvement of goods to make use of this complex therapy.

To enhance lung nodules in CT images, we trained an MTANN filter with 13 lung nodules in a training database which was different from the testing database and the corresponding “teaching” images that contained maps for the “likelihood of being nodules,” as illustrated in Fig. 3a. , binary regions) such that the training regions sufficiently covered nodules and surrounding normal structures. The number of hidden units 22 K. Suzuki was selected to be 20 by use of a method for designing the structure of an ANN (Suzuki et al.

With our current CAD scheme, the multiple graylevel thresholding technique initially identified 20 743 nodule candidates in 1057 sections of LDCT images in the training set. Forty-five of 50 nodules were correctly detected. 02 per section) false positives. 1 mm. In this study, we used all 50 nodules, the locations of which were identified by the radiologist, and all 1078 false positives generated by our CAD scheme in the training set, for investigating the characteristics of the MTANN and training the MTANN.

We applied the selective enhancement filter to the isotropic volumes for enhancing nodules and suppressing vessels. Thresholding followed by the rule-based scheme was applied to the filtered volumes to classify candidates into nodules and non-nodules. Our database contained 62 nodules in 32 scans acquired from 32 patients with an MDCT system with a four-detector scanner. 5 mm). Each CT slice had an image matrix size of 512 Â 512 pixels. Nodule sizes ranged from 5 to 30 mm. All nodules were confirmed by consensus between two chest radiologists.
