Photoacoustic imaging, along with conventional ultrasound, is a hybrid medical imaging modality with unique characteristics. It allows obtaining both physiological events and the molecular composition of tissues together with anatomical information. During the Young Researcher Award (2013/18854-6), a research laboratory dedicated to the development of photoacoustic imaging technologies wa…

There are several reasons why conventional ultrasonography is one of the most widely used modalities in medical imaging. It provides high resolution images in real-time, it does not use ionizing radiation, it is portable, among others. However, this modality is not efficient when molecular and cellular events are to be imaged. Photoacoustic imaging, on the other hand, is a modality that u…
Magnetic hyperthermia is a promising cancer treatment modality; however, challenges such as mapping magnetic nanoparticles (NPs) in tissues and monitoring temperature during treatment hinder this technique to be effectively applied in clinical routine. In order to improve this therapeutic technique, this research project aims to develop and evaluate methods based on ultrasound, photoacous…
Photoacoustic (PA) imaging is a technique used to obtain functional information at molecular levels of human tissue, with simultaneous high contrast and high spatial resolution. On PA imaging, the energy deposited on tissue by pulsed light causes a thermoelastic expansion, and the initial pressure rises, creating ultrasound waves. These waves can be detected by an ultrasound probe to gene…
In medicine, several materials have already been proposed for the composition of phantoms in order to mimic biological tissue for both diagnostic and therapeutic modalities. More specifically in radiotherapy, one must determine both the absorbed dose and its distribution in order to achieve adequate tumor control and lower complications in healthy patient tissues. Current and conventional…
Photoacoustic imaging consists in light absorption by a sample generating acoustic waves due to photoacoustic effect. If temporal stress confinement is satisfied a broadband pressure wave will be generated and photoacoustic images can be acquired using a clinical ultrasound machine. Photoacoustic imaging combines contrast of optical images and spatial resolution of ultrasonic images. Due …
Currently available medical imaging techniques are unable to detect ovarian cancer in its initial stages. In this project, we propose the use of a transvaginal microconvex ultrasound probe to acquire photoacoustic images in order to evaluate the ovarian vasculature. This probe is widely used in gynecological routines due to easier access to the ovaries and is capable of forming images wit…

Photoacoustic imaging (PAI) is a rapidly growing modality with excellent contrast, spatial and temporal resolution, good imaging penetration depth, and capable of obtaining functional and quantitative information from the imaged tissue. Several clinical applications were demonstrated using PAI, revealing the important contribution to this technique for medical images. However, there are s…
Photoacoustics is an area of great and still increasing interest. Photoacoustic imaging is now attracting more investigation since it can provide physio-chemical information of tissue non-invasively. In imaging physics, x-ray acoustic imaging is presented as a new tool that have been discussed for radiation detection during external beam radiation therapy (EBRT), providing opportunities t…
