Abstract :
A position sensitive detector of novel design has been developed to permit CT information to be obtained using a radiotherapy simulator. The scanner has been engineered to obtain the outline of high contrast internal anatomy such as lung tissue and external body contour for the purpose of assisting radiation treatment planning including inhomogeneity corrections. The mode of operation of the scanner is described and the novel reconstruction problem presented by this scanner is discussed. Clinical images are shown which illustrate the usefulness of this scanner in assisting in the conservative management of patients receiving postoperative radiotherapy for breast cancer.
