1. A system for computationally characterizing tissue in an anatomic target region, the system comprising:
an ultrasound transducer comprising a plurality of transducer elements; and
a controller configured to:
(a) cause the transducer to generate a plurality of sonications to transient acoustic reflectors at or proximate to the target region;
(b) measure reflection signals of the sonications off the transient acoustic reflectors;
(c) based on the measurements, identify the reflection signals originating from single transient acoustic reflectors; and
(d) based at least in part on the identified reflection signals, generating a digital map of tissue within the target region, the map including a tissue characteristic.
