Classification of hand bones for bone age assessment
Proceedings of Third International Conference on Electronics, Circuits, and Systems, 2002This paper presents a new approach to classifying bones of the hand-wrist images into pediatric stages of maturity using point distribution models (PDM). The method consists of two phases: the training phase and the classification phase. During training, examples of bones from each class are collected so that the allowable shape deformations for each ...

Bone age assessment: automated techniques coming of age?
Acta Radiologica, 2013Bone age determination from hand radiographs is one of the oldest radiographic procedures. The first atlas was published by Poland in 1898, and to date the Greulich Pyle atlas, although it dates from 1959, is still the most commonly used method. Bone age rating is time-consuming, suffers from an unsatisfactorily high rater variability,

Bone age assessment meets SIFT
SPIE Proceedings, 2015Bone age assessment (BAA) is a method of determining the skeletal maturity and finding the growth disorder in the skeleton of a person. BAA is frequently used in pediatric medicine but also a time-consuming and cumbersome task for a radiologist. Conventionally, the Greulich and Pyle and the Tanner and Whitehouse methods are used for bone age assessment,

Bone age assessment based on phalanx radiograms
2020 IEEE International Instrumentation and Measurement Technology Conference (I2MTC), 2020To identify the growth status of children, more and more bone age assessment (BAA) systems based on Tanner– Whitehouse (TW) method have been developed to estimate skeletal maturity of children. Therefore, with the concept of TW method, our aim is to develop a useful BAA system for the phalanx radiograms.

Carpal bone analysis in bone age assessment
SPIE Proceedings, 2006A computer-aided-diagnosis (CAD) method has been previously developed in our Laboratory based on features extracted from regions of interest (ROI) in phalanges in a digital hand atlas. Due to various factors, including, the diversity of size, shape and orientation of carpal bones, non-uniformity of soft tissue, low contrast between the bony structure ...

Bone Age Assessment by Means of Intelligent Approaches
2021There are many practical applications of intelligent and contextual approaches. The development of systems designed for medical diagnosis is an example of a real world problem employing such approaches. The appropriate understanding of context of digital medical data is crucial in this case.

Automatic bone age assessment: a registration approach
SPIE Proceedings, 2003In this paper we describe a method for registering human hand radiographs (templates) onto a target radiograph for automatic bone age assessment. The method itself constitutes a complete methodology for bone age determination, since it performs similar tasks as the well-known Greulich-Pyle medical technique.

Role of bone scans in assessment of skeletal age
International Journal of Nuclear Medicine and Biology, 1981Abstract Retrospective analysis was carried out, of 252 bone images in patients aged 0–26 y, to answer 2 questions: (1) Which epiphyseal growth plates (EGPs) were identifiable on routine views at each age? (2) Were the EGPs present on both right and left sides and were they symmetrical as determined visually?

The Shorthand Bone Age Assessment
Journal of Pediatric Orthopaedics, 2013Radiographic assessment of skeletal age in pediatric patients is a common practice among orthopaedic surgeons. Current methods of assessment remain labor intensive and require special resources. This study sought to investigate a novel, abridged method of bone age assessment that may serve as a simpler and more efficient alternative to the current ...

The contribution of the carpal bones to the assessment of skeletal age
American Journal of Physical Anthropology, 1965AbstractThe hand‐wrist radiographs of 64 boys and 63 girls were examined to determine the effect of the elimination of the carpal centers from those considered in estimating the skeletal age using the 1959 standards of Greulich and Pyle. The carpals were found to be a source of significant variable error in girls in repeated readings by individual ...
