  A variety of approaches have been used to model the dynamics of a single,
isolated bubble nucleated by a microsecond length high-amplitude ultrasound
pulse (e.g., a histotripsy pulse). Until recently, the lack of single--bubble
experimental radius vs. time data for bubble dynamics under a
well-characterized driving pressure has limited model validation efforts. This
study uses radius vs. time measurements of single, spherical
histotripsy-nucleated bubbles in water [Wilson et al., Phys. Rev. E, 2019, 99,
043103] to quantitatively compare and validate a variety of bubble dynamics
modeling approaches, including compressible and incompressible models as well
as different thermal models. A strategy for inferring an analytic
representation of histotripsy waveforms directly from experimental radius vs.
time and cavitation threshold data is presented. We compare distributions of a
calculated validation metric obtained for each model applied to $88$
experimental data sets. There is minimal distinction ($< 1\%$) among the
modeling approaches for compressibility and thermal effects considered in this
study. These results suggest that our proposed strategy to infer the waveform,
combined with simple models minimizing parametric uncertainty and computational
resource demands accurately represent single-bubble dynamics in histotripsy,
including at and near the maximum bubble radius. Remaining sources of
parametric and model-based uncertainty are discussed.
