Bone extraction and division can enhance the accuracy of diagnoses based on whole-body bone SPECT data. This study developed a method for using conventional SPECT for automatic recognition of the vertebral column. A novel feature of the proposed approach is a novel "bone graph" image description method that represents the connectivity between these image regions to facilitate manipulation of mo...

This paper describes a scheme for reconstructing 3D human models from whole-body scan data. The 3D human models are composed of superquadric primitives each corresponding to a functional body part. The reconstruction starts with primary segmentation of scan data, which defines the location of the articulation link in the human scan and results in topologically simple (primary) body parts. The p...

Accurate capture of encumbered anthropometry is critical to ensure that the analysis and design of military platforms and workspaces account for the additional space required for clothing and PPE equipment. To examine the effect of encumbrance on spatial claim, a method was developed to obtain scan-extracted measures from detailed whole-body shape data. This analysis focused on comparing cross-...

In this issue of the Journal, Schlumberger et al.1 and Mallick et al.2 describe the administration of radioiodine (iodine-131) after total thyroidectomy in patients with low-risk thyroid cancer. Postsurgical treatment has long played an important role in the management of this increasingly common cancer.2 In the United States, the incidence nearly tripled (from 2.7 to 7.7 cases per 100,000) fro...

In September, 2006, a 66-year-old man was admitted to our hospital with a 6-week history of nausea, dysphagia to solids, and abdominal discomfort after eating. His appetite was much reduced, and he reported that he felt sated after eating little food; he had lost 10 kg in weight, and was constantly tired. His past medical history included hypertension, dyslipidaemia, and coronary artery disease...

DESCRIPTION A54-year-old female patientwas referred to our hospital for a chest x-ray due to chest discomfort of 2 months duration. She had a history of thyroid cancer. The chest x-ray demonstrated a large posterior mediastinal mass with smooth borders, displacing the trachea anteriorly (figures 1 and 2). Because of her history of thyroid cancer, a I total body scan was ordered to exclude metas...
