BIOCOMPATIBLE AND ULTRASOUND-DIFFERENTIABLE MICRO-OBJECTS SUITABLE FOR IMPLANTATION IN A VERTEBRATE SUBJECT

摘要

Described embodiments include a system. A described system includes a set of at least two biocompatible and ultrasound-differentiable micro-objects suitable for implantation in a vertebrate subject. Each micro-object of the set of micro-objects while implanted respectively returning an echo response to an applied ultrasound energy having a machine recognizable feature differentiating the micro-object over each other micro-object of the set of micro-objects (hereafter "set of micro-objects"). The system includes a conversion table correlating each digit of the conversion table base system with a respective machine recognizable feature in an echo response to an ultrasound energy applied to a micro-object of the set of micro-objects. In an embodiment, the system includes a packaging material carrying the set of micro-objects and the conversion table.
