Special Issue Information
Dear Colleagues,
Photoacoustic imaging has successfully served as an imaging tool in biomedical applications, which take advantage of its optical contrast, ultrasonic spatial resolution, and ultrasonic imaging depth. Additionally, photoacoustic and ultrasound imaging are relatively easy to combine in order to maximize their advantages while compensating for each other’s disadvantages. In this dual imaging modality, photoacoustic images provide optically contrasted functional information about target lesions, whereas ultrasound images are used to identify the anatomical location of the target lesions. Recently, many attempts have been made to expand the use of photoacoustic imaging to clinical applications such as the diagnosis of breast and prostate cancers. The objective of this Special Issue is to highlight technological advances in photoacoustic imaging and clinical applications of photoacoustic imaging that have recently been developed.
In recent years, although the scanning and image formation methods of photoacoustic imaging have become relatively mature, the application of photoacoustic imaging has increased explosively. Cross-disciplinary research with chemistry and life sciences has significantly promoted the progress of photoacoustic imaging. Various contrast agents, including nanoparticles, organic dyes, targeted agents, and genetically expressed markers, are being actively developed. Photoacoustic imaging has been applied in studies involving the release control and the monitoring of the dynamics of these contrast agents. Clinical translations of photoacoustic imaging have also achieved remarkable progress. On the other hand, there are still needs in some aspects, such as large depth detection, miniaturization of endoscopic probe, and fast multi-spectral imaging. Advanced imaging models, image reconstruction methods, and signal processing algorithms have been invented to reduce the scanning time and enhance the image quality. The emergence of new laser sources, non-contact ultrasound detection technologies, and novel ultrasound sensors are also important aspects of photoacoustic innovation.
This Special Issue aims to present original state-of-the-art research articles on almost all aspects of photoacoustic imaging. However, studies mainly about the synthesis and characterization of photoacoustic contrast agents, with only marginal relation to photoacoustic imaging, are outside the scope of this Issue. Topics include, but are not limited to:
- Tomography and deep-tissue imaging;
- Photoacoustic microscopy;
- Contrast agents, molecular probes, and nanoparticles;
- Pre-clinical imaging, clinical translation, and clinical applications;
- Multi-modality systems involving light and sound;
- Microwave-induced ultrasound imaging and sensing;
- Laser ultrasound methods and applications;
- Physics and modeling of photoacoustic generation, propagation and detection;
- Advanced photoacoustic and ultrasound signal processing and analysis;
- Image reconstruction algorithms including deep learning;
- Novel lasers and light delivery technologies for the generation and detection of ultrasound;
- Spectroscopy and analysis of compounds.
