1. A transducer-activation system comprising:
an input-output device system;
a memory device system storing a program; and
a data processing device system communicatively connected to the input-output device system and the memory device system, the data processing device system configured at least by the program at least to:
receive, via the input-output device system, a selection of multiple transducers from a plurality of transducers of a transducer-based device, the plurality of transducers arranged in a distribution, and the distribution positionable in a bodily cavity; and
cause, via the input-output device system and after the reception of the selection of the multiple transducers, activation of the multiple transducers to cause tissue ablation,
wherein the activation of the multiple transducers is configured to include a sequential activation of multiple subsets of transducers of the multiple transducers,
wherein the activation of the multiple transducers is configured to include a first bipolar activation at a first time of each pair of a first set of one or more pairs of transducers selected from a first subset of transducers of the multiple subsets of transducers, the first set of one or more pairs of transducers including a first pair of transducers, the first pair of transducers including a first transducer and a second transducer of the multiple transducers,
wherein the activation of the multiple transducers is configured to include a second bipolar activation at a second time after the first time of each pair of a second set of one or more pairs of transducers selected from a second subset of transducers of the multiple subsets of transducers, each pair of transducers of the multiple transducers caused to be activated at the second time being other than the first pair of transducers, and
wherein the activation of the multiple transducers is configured to include a third bipolar activation after the second time of each pair of a third set of pairs of transducers selected from a third subset of transducers of the multiple subsets of transducers, the third set of pairs of transducers including the first transducer and the second transducer.
