Background:
Visual examination and cutaneous biopsies, two major tools in dermatologic diagnosis, do not provide structural information regarding the entire tissue volume.
Objective:
Our purpose was to develop a high-resolution ultrasound system that quickly, with minimal operator interaction, displays structural data on the entire tissue volume.
Methods:
A prototype ultrasound B-scan system was developed and operated at nominal center frequencies between 35 and 50 MHz, with computer processing of data to produce three-dimensional images. These images displayed as three-dimensional "blocks" can be sectioned to provide multiple images of internal structure (i.e., "acoustic biopsies").
Results:
B-scans and associated three-dimensional images were obtained from assorted skin sites in selected patients.
Conclusion:
This technique provides a valuable diagnostic tool that is now being further evaluated.
