PROBLEM TO BE SOLVED: To provide a method for volume rendering a digitized medical image overcoming the problems of the prior art. SOLUTION: This method for volume rendering a digitized medical image includes: a step of providing a digitized medical image volume; a step of providing a projection plane; a step of projecting rendering rays from a viewing point through the image volume, and advancing a sampling point along a ray through the image volume; a step of generating an incision region within the image volume; and a step of determining whether or not the sampling point is within the incision region, wherein a first transfer function is applied to a sample value interpolated from a first volume if the sampling point is within the incision region, and a second transfer function is applied to a sample value interpolated from a second volume if the sampling point is outside the incision region, and the outputs of the transfer functions are accumulated.
