An Ultra-Low-Cost Optoacoustic Method for Imaging Specific Biological Structures

Area of Science:

• Biomedical imaging
• Optoacoustic technology
• Medical device development

Background:

• Optoacoustic imaging offers unique contrast and penetration but faces complexity and cost challenges with current tomographic methods.
• Existing optoacoustic tomography systems are often bulky, expensive, and require specialized operation.
• There is a need for simplified, cost-effective optoacoustic solutions for broader clinical adoption.

Purpose of the Study:

• To develop and evaluate a non-tomographic optoacoustic imaging method using a single ultrasound transducer.
• To overcome the complexity and cost limitations of traditional optoacoustic tomography.
• To enable imaging of layered biological structures in a user-friendly, compact system.

Main Methods:

• Implementation of a single-transducer, non-tomographic optoacoustic imaging system.
• Testing performance through simulations, synthetic phantoms, and biological phantoms with tattoo ink.
• Focus on user-friendliness, compactness, simplicity, and low cost.

Main Results:

• The system successfully discriminates and recovers slab-like structures with high axial resolution.
• Demonstrated capability to image structures like tattoo ink, subcutaneous fat, and muscles.
• The system shows potential for improving tattoo removal procedures and applications in pediatrics, traumatology, and endocrinology.

Conclusions:

• This work introduces a new generation of simple, easy-to-use, and low-cost optoacoustic imaging systems.
• The non-tomographic approach offers a viable alternative to complex tomographic methods.
• The technology has the potential for significant impact across various medical fields.
