This study seeks to compare fixed-field intensity-modulated radiation therapy (FF IMRT), RapidArc (RA), and helical tomotherapy (HT) to discover the optimal treatment modality to deliver SBRT to the peripheral lung. Eight patients with peripheral primary lung cancer were reviewed. Plans were prescribed a dose of 48 Gy and optimized similarly with heterogeneity corrections. Plan quality was asse...

The Department of Defense High Performance Computing Modernization Program (HPCMP) seeks to bring technology to the warfighter. High performance software is being developed by the Common Highperformance Software Support Initiative (CHSSI) component of the program. High-performance software and technology are being transferred to DoD users throughout the MSRC-supported Programming Environment an...

In five normal men, we divided the rib cage into lung-apposed [pulmonary rib cage (RCp)] and diaphragm-apposed [abdominal rib cage (RCab)] compartments and calculated their absolute cross-sectional areas (Arc,p and Arc,ab) by anteroposterior and lateral dimensions measured by magnetometry. Distortion was quantified as the displacement of RCp and RCab produced by diaphragmatic twitches away from...

During the first half of this century, various syndromes attributed to compression of neural and vascular structures in the anatomic area of the thoracic outlet have been described. These include the cervical rib, scalene anticus, costoclavicular, first dorsal rib, and hyperabduction syndromes. This complex array of subdivisions has engendered some confusion in diagnosis and treatment. Although...

Using respiratory inductive plethysmography, we have measured rib cage and abdominal motion during isoflurane anaesthesia in 16 healthy day-surgery patients. Anaesthesia was induced with propofol and maintained with 1 MAC isoflurane in air-oxygen via a laryngeal mask. Measurements were taken during both resting ventilation and hyperpnoea induced by rebreathing carbon dioxide. For resting ventil...

In this study, we used analytic morphomics to understand the mechanisms of rib fracture for older occupants in frontal crashes. Analytic morphomics extracts body features from computed tomography scans of people involved in vehicle crashes who have been treated at the University of Michigan, a Level‐1 trauma center. Chest injury and rib fracture patterns w...

PURPOSE The purpose of this study was to present the outcome and discuss the feasibility of rib composite flap with intercostal nerve and internal thoracic vessels for reconstructing mandibular defect. METHODS Rib composite flaps have been used in 82 patients for reconstructing benign tumor-caused large mandibular defects: 66 of the 82 patients were reconstructed using rib composite flap with...

Introduction Anatomical variations of human ribs have been well documented [1–3]. Common variations include asymmetric ribs, cervical or lumbar ribs, fusion of rib 1 and 2 and the absence of rib 1 [2, 3]. Unusual variants include fibrous tissue replacing costal cartilage, ribs bifurcated at the sternal insertion, two adjacent ribs articulating at their costal cartilages by a diarthrosis, synart...

Experimental testing is a major source of data to quantify the tolerance of the human body to impact and to develop protection strategies. Correlating the time of rib fractures with the kinematics of the occupant and the action of safety systems would provide valuable data for assessing safety systems and developing injury risk functions. However, methods for determining rib fractures timing ar...

A syndrome of back and loin pain produced by impingement of the lowest rib against the iliac crest is described in six patients. All had noticed a significant loss of height and five had osteoporosis of the vertebral column. It is suggested that mechanical irritation of the lowest rib against the iliac crest was the cause of the pain and that subperiosteal resection of the outer two-thirds of t...
