This study introduces a new urethral device for real-time prostate cancer imaging during biopsies. The device improves light penetration for better lesion detection, enhancing diagnostic accuracy.
Area of Science:
- Medical Imaging
- Biomedical Engineering
- Oncology
Background:
- Prostate cancer diagnosis relies on biopsies, lacking real-time guidance for suspicious lesions.
- Photoacoustic tomography offers chemical selectivity for targeted biopsies but faces light penetration challenges.
Purpose of the Study:
- To develop a novel urethral device for whole-prostate photoacoustic imaging.
- To overcome limitations in light delivery for anterior prostate visualization.
Main Methods:
- A urethral device with cylindrical illumination was designed and fabricated.
- Performance was evaluated using a prostate-mimicking phantom, assessing angular light coupling.
Main Results:
- The developed urethral device enables whole-prostate imaging.
- Evaluation confirmed the device's potential for improved light delivery to the anterior prostate.
Conclusions:
- The urethral photoacoustic imaging device shows promise for real-time prostate biopsy guidance.
- This technology could enhance the accuracy and efficiency of prostate cancer diagnosis.
