title: Corrections to absorbed dose calculations for tissue inhomogeneities.
abstract: Traditional methods for correcting for the presence of tissue inhomogeneities may produce errors as great as 10% at points within or closese to the inhomogeneities. Measurements were made in phantoms containing aluminum or cork inhomogeneities. Agreement between measured and predicted results was usually within 2%-3%.
