Book Description
COMPUTER ASSISTED BONE AGE ASSESSMENT Bone age assessment based on the radiological examination of the left hand and wrist is a procedure frequently performed to evaluate the growth of pediatric patients. In this thesis we examined studies conducted on the skeletal age analysis and we developed a computerized system for automatic bone age analysis. Firstly we examined two different clinical methods; The Greulich and Pyle method and the Tanner and Whitehouse (TW2) method. We chose the TW2 method to develop a computerized bone age system because it is more suitable for the computer analysis than the Greulich and Pyle method. We developed the web-based TW2 skeletal age calculation software. We then introduced steps that are necessary to transform this manual clinical method into a fully automated system. We explained preprocessing methods that are needed to make a radiograph fit for analysis and steps to find regions of interest and assign them TW2 stages. Finally we developed a computer program that assigns TW2 stages to a certain region of interest (the middle phalanx of the third finger) in the left hand. In this method we trained all TW2 stage groups for middle phalanx of the third finger and produced mean images for each TW2 stage. These mean images are used to determine the TW2 stage of queried image. We use the correlation between a mean image and a target image as an indicator of which stage should be assigned to the target. Our results show that 70 % of all test images of the middle phalanx of the third finger have been assigned the correct TW2 stage by our method. We believe that the same method could be used to assign TW2 stages to other regions of interest in the hand.

Book Description
In the past, determination of bone maturity relied on visual evaluation of skeletal development in the hand and wrist, most commonly using the Greulich and Pyle atlas. The Gilsanz and Ratib digital atlas takes advantage of digital imaging and provides a more effective and objective approach to assessment of skeletal maturity. The atlas integrates the key morphological features of ossification in the bones of the hand and wrist and provides idealized, sex- and age-specific images of skeletal development New to this revised second edition is a description and user manual for Bone Age for iPad®, iPhone® and iPod touch®, which can be purchased and used separately from this book. The App can be easily employed to calculate the deviation of the patient’s age from the normal range and to predict a possible growth delay. This easy-to-use atlas and the related App will be invaluable for radiologists, endocrinologists, and pediatricians and also relevant to forensic physicians.

Book Description
This book is a comprehensive and practical guide to assessing skeletal maturity and predicting adult height in children. It takes the reader through the main scoring systems and uses radiographs to illustrate the main stages of bone maturity in male and female children. The FREE CD-ROM contains a growth height prediction program, helping to predict growth height for each patient and storing data for comparison as the patient grows.

Book Description
Bone age assessment, a crucial part of the diagnosis and management of pediatric growth disorders as well as the timing of certain pediatric orthopedic procedures, has for decades depended on the meticulous examination of plain radiographs. Examining the subtle changes present within the maturing human hand often proves to be challenging and time-consuming. Building on the popular Greulich and Pyle atlas, this book modernizes the method for pediatric skeletal maturity determination. It offers a wealth of images, carefully mined from thousands of digital radiographs from University of Virginia's Picture Archiving and Communication System (PACS), edited to best demonstrate important developmental bone features, and organized by age and sex for rapid reference. To expedite learning and clinical image analysis, images come in pairs: annotated and unannotated, for easy comparison. Succinct annotations on the images replace lengthy text to provide a quicker and clearer understanding of the skeletal age. These annotations highlight important and subtle features to help distinguish images that otherwise look superficially alike. The result is an atlas of exceptionally high quality skeletal radiographic standards that capture both the major and finer details of the accepted standards of Greulich and Pyle. The user-friendly format of this book enables a faster, more accurate, and more educational approach to determining skeletal maturity. The Digital Bone Age Companion packaged with the book is a computer program that facilitates viewing of the atlas images in digital format. Users can easily zoom in on radiographic features, set image level and width to their preference, and compare two or three reference standards side-by-side for difficult cases. Most importantly, the program expedites evaluation, optimizes workflow, and minimizes user-introduced errors with the reliable bone age calculator and built-in report generator. The digital format may also be available for integration with your Radiology Information System (RIS) for further workflow enhancement. Given the broad application of pediatric bone aging, Skeletal Development of the Hand and Wrist is not only intended for practicing and training radiologists, but for all of those who employ bone age studies as part of their practice.

Book Description
The objective of this Brief is to provide a solution to the unsolved technical problem in segmentation for the automated bone age assessment system. The task is accomplished by first applying the modified histogram equalized module, then applying the proposed automated anisotropic diffusion technique. It is followed by a novel fuzzy quadruple division scheme to optimize the central segmentation algorithm, and then an additional quality assurance scheme. The designed segmentation framework works without demanding scarce resources such as training sets and skillful operators. The results have shown that the designed framework is capable of separating the soft-tissue and background from the hand bone with high accuracy. This Brief should be especially useful for students and professional researchers in the Biomedical and image processing fields.
