1. A system comprising:
an input-output device system including a catheter device system, the catheter device system including a plurality of transducers, a distribution of the plurality of transducers positionable in a bodily cavity, the bodily cavity defined by at least a tissue wall, and each transducer of the plurality of transducers configured at least to sense a degree of contact between the transducer and the tissue wall;
a data processing device system communicatively connected to the input-output device system and to the plurality of transducers of the catheter device system of the input-output device system; and
a memory device system communicatively connected to the data processing device system and storing a first contact-improvement procedure in association with a first transducer set of the plurality of transducers, the memory device system further storing a program executable by the data processing device system,
wherein the data processing device system is configured by the program at least to:
receive, via the input-output device system, a plurality of degree-of-contact signals respectively from the plurality of transducers, the plurality of degree-of-contact signals respectively indicating a degree of contact between the respective transducer of the plurality of transducers and the tissue wall;
identify a particular transducer of the plurality of transducers as belonging to the first transducer set and as exhibiting an improper contact arrangement with the tissue wall as compared to a predetermined tissue-contact state, based at least on an interaction with data associated with at least one of the received degree-of-contact signals; and
cause the input-output device system, in response to the identifying of the particular transducer as belonging to the first transducer set and as exhibiting the improper contact arrangement with the tissue wall as compared to the predetermined tissue-contact state, to provide an indication of the first contact-improvement procedure to facilitate an improved contact arrangement between one or more transducers in the first transducer set and the tissue wall.
