Systems for providing time varying density signatures of tissues are presented. The time varying density signatures can be calculated based on obtained sensor data reflecting one or more properties (e.g., physical, mechanical, electrical, etc.) of a target tissue. The time varying density signatures can then be used to generate an output where the output indicates how a target tissue's density changes with respect to time, possibly based on first, second, third, or higher order derivatives with respect to time.
