The effect of the size of the Hessian multiscale filters on the prescreening performance. The plot shows the fraction of true clusters in the data set that included a cluster seed object as a function of the rank of the objects that were retained per DBT volume. In this part of the investigation, the SNR enhancement filter kernels were fixed at ${\mathrm{M}}_1=0.7$ mm, ${\mathrm{M}}_2=0.1$ mm, and ${\mathrm{M}}_3=0.1$ mm.
