Frontal and lateral views of the brain reconstructed from EMI axial slices
RA Schulz, PM Joseph and SK Hilal
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.
