1. A method of determining, during a medical procedure, an anatomical identity of a first intrabody region which is a region included in a second intrabody region, the first and second intrabody regions being, in a body of a patient undergoing the medical procedure, the procedure using an intrabody probe, the method characterizing a position of the intrabody probe, and the method comprising:
receiving data indicating that the intrabody probe is operating in an operational context, a specification of the operational context including a condition indicative of proximity of the intrabody probe to the second intrabody region;
receiving input data from the intrabody probe indicating one or more measured properties of the first intrabody region;
wherein the input data is received while the intrabody probe moves, and the condition indicative of proximity remains satisfied;
selecting at least one rule for anatomical identification from an anatomical schema, wherein the at least one rule is selected, based on the operational context, from a set of a plurality of different rules, wherein one or more of said different rules is associated with one or more operational contexts different from and exclusive to said operational context; and
applying the at least one rule to the input data, to determine anatomical identity of the first intrabody region, also while the condition indicative of proximity remains satisfied, thereby characterizing the position of the intrabody probe with respect to the first intrabody region included in the second intrabody region.
