introduction: one cause of death among people aged under 40 is trauma which in increasing mainly because of increase in use of vehicles. there has been an increase in trauma and its mortality worldwide, resulting in lost of life years due to the consequent disabilities. however, we can prevent the mortality & complications due to trauma in particular, thorax trauma through intense & urgent care...
The management of intra-fractional respiratory motion is becoming increasingly important in radiation therapy. Based on in advance acquired accurate 3D CT data and intra-fractionally recorded noisy timeof-flight (ToF) range data an improved treatment can be achieved. In this paper, a variational approach for the joint registration of the thorax surface extracted from a CT and a ToF image and th...
The patient is a 66-year-old woman who had undergone a right extrapleural pneumonectomy 2 years earlier for pleural mesothelioma (stage II) and had received adjuvant chemoand radiotherapy. During the procedure, a Gore-Tex patch was used to reconstruct the diaphragm. Six months after surgery, a follow-up MRI was ordered due to high transaminase levels, and herniation of the liver into the thorax...
Rigidity of the thorax in ankylosing spondylitis was first recognized as long ago as 1695, when Bernard Connor described a skeleton showing the characteristic rigidity of the thoracic cage and lumbar spine and concluded that respiration must have been greatly restricted during the life of the unfortunate sufferer. This astute observation remained the only one of its kind until Hilton Fagge (187...
We are now about half way through our term of office (unless we are prematurely fired for terminal misbehaviour); here we review where we are, and where we are going, and have the first instalment of the showcase of some of our best articles from last year. We have maintained our second position with an improved impact factor (6.84) over 2011, we continue to attract very high quality manuscript...
Basal cell carcinoma (BCC) is the most common human malignancy, accounting for the majority of all non-melanoma skin cancers (NMSC). In the past several decades the worldwide incidence of BCC has constantly been increasing. Even though it is a slow growing tumour that, left untreated, rarely metastasizes, it has a distinctive invasive growth pattern, posing a considerable risk for local invasio...
Nonrigid image registration is widely used to estimate tissue deformations in highly deformable anatomies. Among the existing methods, nonparametric registration algorithms such as optical flow, or Demons, usually have the advantage of being fast and easy to use. Recently, a diffeomorphic version of the Demons algorithm was proposed. This provides the advantage of producing invertible displacem...
