title: Frontal and lateral views of the brain reconstructed from EMI axial slices.
abstract: A computer program has been written to produce lateral and frontal views of the brain from transverse slices generated by the EMI scanner. The resulting images have markedly facilitated the planning of surgical exploration of intracranial lesions by graphically indicating their locations in a manner consistent with the familiar lateral and frontal radiographs. Our image is formed from a distribution of the average EMI density number along the directio, of projection. Incorporated in the program is a bone-searching algorithm which eliminated density from the cranium and extracranial air and water so that only brain is seen in the projection. Several enhancement algorithms are provided to enhance pathology. The images are displayed on the existing EMI viewer, where they are available for inspection and photography.
