Abstract
For use in acoustic micro imaging, a method (and implementing apparatus) is disclosed for creating a 4D virtual sample data memory. The method comprises employing a pulsed ultrasonic microscope probe to interrogate a sample at three-dimensionally varied locations in the sample. Data developed by the microscope probe includes for each location interrogated a digitized A-scan for that location. The developed data is stored in a data memory.
Claims9
A method for use in micro-imaging, said method comprising the steps of:
- emitting a pulse of acoustic energy from a transducer toward each one of a plurality of three-dimensionally varied points located within a given volume that is defined inside of a sample;
- causing said transducer to have, for each one of said pulses, a focal point that is disposed at the same location within the given volume of the sample as the corresponding one of the three dimensionally varied points;
- using said transducer to receive at least a portion of a reflection signal that corresponds to each one of said emitted pulses;
- and
- storing in a data memory at least a portion of said reflections signals,
- wherein each one of said reflection signals comprises an A-Scan of the sample that is in-focus at the point within the given volume of the sample corresponding thereto.
