Three-dimensional conformal radiotherapy and intensity modulated radiotherapy allow accurate dose delivery on target volumes. Due to the different background among specialists involved in target volume definition, the contouring emerges as one of the most questionable steps in treatment planning procedures. A software tool devoted to contouring training, named tutorial for image guided external radiotherapy ('TIGER'), based on the Visible Human Project images data-set, is described.
TIGER is addressed to facilitate the learning of axial anatomical images, to promote the training and reproducibility in contouring process, to allow the availability of a tool to enhance the 'drill and practice' approach in training programs. TIGER includes three different environments: Anatomic tutorial devoted to facilitate a self-learning approach to axial body sections; Contouring tutorial addressed to practice contouring process of anatomical structures and to undergo a test program prepared by tutors; Teacher's tools to offer to tutors the opportunity to insert new outlines in TIGER-database, according to local needs or conventions, and to use them in tutorial programs. TIGER-database is grouped in six main anatomical sections: head and neck, male thorax, female thorax, abdomen, male pelvis, and female pelvis. Overall 432 corresponding CT-VH images and 1189 contours of 134 different anatomical structures and lymphatic drainage areas are available. The access to the TIGER software is allowed by ESTRO web site (
TIGER provides an interactive human anatomy cross-sectional oriented source to facilitate the interpretation of CT scan images usually contoured in daily practice. It offers a drill tool to facilitate the learning of a reproducible contouring procedure.

    • "Online platforms are useful tools for teaching, training and education of health care professionals. There are a limited number of studies examining web-based training for radiation oncology clinicians [1] [2] as well as community general practitioners in the management of patients who have had radiation treatment [3]. There have also been descriptions of how to design a radiation oncology curriculum for e-Learning [4]. "

    ABSTRACT: Background and purpose: An e-Learning programme appeared useful for providing training and information regarding a multi-centre image guided radiotherapy trial. The aim of this study is to demonstrate the utility of this e-Learning programme. Materials and methods: Modules were created on relevant pelvic anatomy, Cone Beam CT soft tissue recognition and trial details. Radiation therapist participants' knowledge and confidence were evaluated before, at the end of, and after at least 6 weeks of e-Learning (long term). Results: One hundred and eighty-five participants were recruited from 12 centres, with 118 in the first, and 67 in the second cohort. One hundred and forty-six participants had two tests (pre and post e-Learning) and 39 of these had three tests (pre, post, and long term). There was an increase confidence after completion of modules (p<0.001). The first cohort pre scores increased from 67 ± 11 to 79 ± 8 (p<0.001) post. The long term same question score was 73 ± 14 (p=0.025, comparing to pre-test), and different questions' score was 77 ± 13 (p=0.014). In the second cohort, pre-test scores were 64 ± 10, post-test same question score 78 ± 9 (p<0.001) and different questions' score 81 ± 11 (p<0.001). Conclusions: e-Learning for a multi-centre clinical trial was feasible and improved confidence and knowledge.

    • "'Visible Korean Human (VKH)' project [4] and 'Chinese Visible Human (CVH)' project [5] were carried out for producing their own visible human datasets in 2000 and 2001, respectively. After being obtained these visible human anatomy datasets, VHP datasets, VKH datasets and CVH datasets have been widely used in all kinds of fields, and lots of researches and applications have been carried through with adopting different visible human datasets by scientists all over the world [6] [7] [8] [9] [10].

    ABSTRACT: Following the 'Chinese Visible Human (CVH)' project which afforded datasets of a complete normal adult male and a complete normal adult female from Asian population, 'Mechanical Virtual Human of China (MVHC)' project supported by National Natural Science Foundation was initiated on January 2006. One of MVHC project's purposes is to construct a three-dimensional (3D) musculoskeletal system model and a 3D skeletal system finite element (FE) model of a whole male, which are absolutely obedience to the true anatomical structure in geometry with adopting CVH male dataset. This paper gives how 3D musculoskeletal system model and 3D skeletal system FE model of a whole male were constructed, and displays these models at the same time. 3D musculoskeletal system model and 3D skeletal system FE model of a whole human could be as the foundation of kinematics, dynamics and stress/strain analysis under lots of conditions, and will find wide applications in such areas as medical engineering, medical instrument design, physical and art education, sport, ergonomics and traffic accident analysis etc.
