چکیده

Scoliosis is a lateral or sideways deviation of the spine or vertebral column. Scoliosis can be treated by postural correction, providing braces or by surgery. Even after treating scoliosis with the help of brace or surgery, the normal spine range of motion is not achieved in most cases. After treating scoliosis either by brace or surgery, the normal posture might be achieved. But, it is important to know whether the patient is able regain his/her functionality. The mechanical properties of the vertebrae and intervertebral disc pressure after the application of brace and surgery are unknown and yet to be explored. In order to explore it, we come up with the thought of creating a 3D model of vertebrae. Because scientists and researchers depend upon cadaver specimens to try new fixations where the number of people willing to donate their body for research purpose is very low or nil in most of the countries. Without a sufficient number of cadaver specimens, the research progress remains still or very slow. Thus, creating a 3D model of vertebrae could yield more importance and convenience to do spine research. A 3D model of human spine can help in 3D printing too. In this study, we propose a simple method where the 3D model of scoliotic vertebrae can be created with the help of DICOM files.

Design, Construction and Evaluation of an Anthropomorphic Head Phantom for Assessment of Image Distortion in Stereotactic Radiosurgery Planning Systems

Introduction: In recent years, the use of magnetic resonance (MR) images in radiation treatment planning has drawn considerable attention. However, although the extent of a tumor can be determined in great detail on MR images, the geometric accuracy of these images is limited by distortions stemming from the inhomogeneity of the static background magnetic field, the nonlineari...

Optimization of clinical target volume delineation using magnetic resonance spectroscopic imaging (MRSI) in 3D conformal radiotherapy of prostate cancer

Background: For the purpose of individual clinical target volume assessment in radiotherapy of prostate cancer, MRSI was used as a molecular imaging modality with MRI and CT images. Materials and Methods: The images of 20 prostate cancer patients were used in this study. The MR and MRSI images were registered with CT ones using non-rigid registration technique. The CT based planning (BP), CT/MR...
