We present a measurement of the $t\overline{t}$ production cross section using $194\text{ }{\mathrm{pb}}^{\ensuremath{-}1}$ of CDF II data using events with a high transverse momentum electron or muon, three or more jets, and missing transverse energy. The measurement assumes 100% $t\ensuremath{\rightarrow}Wb$ branching fraction. Events consistent with $t\overline{t}$ decay are found by identifying jets containing heavy-flavor semileptonic decays to muons. The dominant backgrounds are evaluated directly from the data. Based on 20 candidate events and an expected background of $9.5\ifmmode\pm\else\textpm\fi{}1.1$ events, we measure a production cross section of $5.3\ifmmode\pm\else\textpm\fi{}{3.3}_{\ensuremath{-}1.0}^{+1.3}\text{ }\mathrm{pb}$, in agreement with the standard model.
