Tissue-mimicking phantoms for photoacoustic and ultrasonic imaging

In both photoacoustic (PA) and ultrasonic (US) imaging, overall image quality is influenced by the optical and acoustical properties of the medium. Consequently, with the increased use of combined PA and US (PAUS) imaging in preclinical and clinical applications, the ability to provide phantoms that are capable of mimicking desired properties of soft tissues is critical. To this end, gelatin-ba...

Gel wax-based tissue-mimicking phantoms for multispectral photoacoustic imaging

Tissue-mimicking phantoms are widely used for the calibration, evaluation and standardisation of medical imaging systems, and for clinical training. For photoacoustic imaging, tissue-mimicking materials (TMMs) that have tuneable optical and acoustic properties, high stability, and mechanical robustness are highly desired. In this study, gel wax is introduced as a TMM that satisfies these criter...

Photoacoustic Imaging of a Non- Targeted Contrast Agent in Breast- Tissue-Mimicking Phantoms

Our preliminary photoacoustic data indicates that we could detect small objects (tubes with a cross-section of 1mm) containing 100 micro moles of contrast agent up to about 5cm in the breast-tissue like environment. For the case of 10 micro moles concentration of the dye, we could detect such small objects up to about 3cm. This depth can be increased further (by at least another 2cm) by the use...

Photoacoustic microscopy of bilirubin in tissue phantoms.

Determining both bilirubin's concentration and its spatial distribution are important in disease diagnosis. Here, for the first time, we applied quantitative multiwavelength photoacoustic microscopy (PAM) to detect bilirubin concentration and distribution simultaneously. By measuring tissue-mimicking phantoms with different bilirubin concentrations, we showed that the root-mean-square error of ...

Pulsed photoacoustic Doppler flow measurements in blood-mimicking phantoms

The feasibility of making spatially resolved measurements of blood flow using pulsed photoacoustic Doppler techniques has been explored. Doppler time shifts were quantified via cross-correlation of pairs of photoacoustic waveforms generated within a blood-simulating phantom using pairs of laser light pulses. The photoacoustic waves were detected using a focussed or planar PZT ultrasound transdu...
