Photoacoustic imaging (PAI) is now a very promising medical imaging technology that provides structural, functional, and molecular information based on the optical absorption of endogenous or exogenous contrast agents. A conventional PAI system using an array of ultrasonic transducers to detect photoacoustic (PA) signals. Each element of the transducer requires an amplifier to enhance the detected signal which makes it bulky. To overcome this problem, we introduced optical sensor alternative to piezoelectric ultrasound detector in PA signal detection. This study aims to illustrate the entire process of PA signal generation and its detection using an optical sensor using Finite Element software (COMSOL). Fiber Bragg grating (FBG) is one of the optical sensors that may be utilized in some applications in place of acoustic ones. FBG provides the change in acoustic pressure as a function of the shift of Bragg wavelength. Our study demonstrated that FBG achieves to detect photoacoustic (PA) signals as an alternative of US transducer, with superior performance in terms of sensitivity, and being more light-weight, flexible, and cost-effective. This implies that these technologically novel qualities hold promise for the use of FBG (either single or multiple units on a single fiber) as an acoustic sensor in PAI systems in place of the conventional piezoelectric-based bulk array transducer. An intensity-based demodulation was performed to extract the US signal. The preliminary study demonstrates that the integration of FBG in PA imaging modality offers potential as a future (imaging) technology both for biological studies and clinical applications.

The use of polymer as conductor in medical ultrasonography is very crucial to establish patient diagnosis and to prevent administration of improper treatment. Rapid development in science and technology encourages people to create more innovations that are readily usable. However, these innovations sometimes put health and environmental aspects aside that in turn become disadvantageous to health and may lead to environmental pollution. This research proposes the use of carrageenan biopolymer as a safe alternative for people’s health and the environment. It aims to prove differences in resulting phantom CIRS images taken with the help of carrageenan gel and standard gel based on Carbomer 940 as acoustic coupling agents (ACA) for ultrasonography (USG). It is an experimental research that uses true experiment technique with posttest only control group design. Results from T-test analysis show significance value of p>0.05, meaning there is no significant difference between the use of carrageenan gel and ACA gel (Carbomer 940). This result proves that carrageenan gel can be used as an acoustic coupling agent for ultrasonography. Results from imaging tests also reveal that there is no difference between the use of carrageenan gel and that of a manufacturer gel based on Carbomer 940 available in Indonesia, in terms of visualization of phantom CIRS images.
