background: the aim of this work was to study the feasibility of constructing a fast thorax model suitable for simulating lung motion due to respiration using only one ct dataset. materials and methods: for each of six patients with different thorax sizes, two sets of ct images were obtained in single-breath-hold inhale and exhale stages in the supine position. the ct images were then analyzed ...

Image-guided surgery and therapy is assuming an increasingly important role, particularly considering the current emphasis on minimally-invasive surgical procedures. Volumetric CT and MR images have been used now for some time in conjunction with stereotactic frames, to guide many neurosurgical procedures. With the development of systems that permit surgical instruments to be tracked in space, ...

After the introduction of MRI, new modalities facilitated the procedure of surgical planning to achieve the microsurgical goal and improve prognosis and quality of life in patients. Despite the variable applications of preoperative and intraoperative mapping and monitoring systems, several limitations and concerns are reported for every modality as well. In this issue of the IrJNS, we are delig...
