Magnification Device of Computed Tomography in Radiation Therapy Planning / 대한치료방사선과학회지

Computed tomography(CT) adds a new dimension in the study of body contour, organs and tissues as well as various pathologic conditions. This modality provides a great degree of accuracy in radiation therapy planning(RTP). However, CT images are usually taken on a small reduced format so that possible errors can be made during inputting the CT data into an automatic planner. Authors have designed a simple inexpensive magnifying device of CT images to obviate errors created by reduced image.
