Research Fields

The GIIMUS laboratory aims to develop research in the fields of biomedical  instrumentation and signal processing. We are especially interested in applying ultrasonic waves associated with magnetism and optics to develop new medical diagnostic and therapeutical procedures.

The Research Fields are:

1 – Biomedical Instrumentation – This area includes the development and characterization of transducers and building protocols and analysis measures to support the control of human health … Read More >>

2 – Tissue Characterization – This area includes ultrasound imaging techniques such as Elastography and Acoustography. Both of which are noninvasive and effective methods for medical diagnosis. Ultrasound elastography is a novel medical imaging modality able to evaluate the stiffness of human tissue. In ultrasound acoustography, the nonlinear propagation of acoustic waves and ultrasonic mechanical vibrational response of structures inside the medium are explored as a device for imaging at frequencies on the order of kilohertz (kHz), from input with ultrasonic waves in order MHz … Read More >>

3 – Photoacoustic Imaging – The Photoacoustic effect, in which sound is generated due to the absorption of light by a material, provides access to a type of medical imaging with unique features. These images can represent both physiological events in the body, as indicating the molecular composition of a tissue … Read More >>

4 – Tissue-mimicking Phantom – The need and interest from health professionals conduct training in clinical procedures with high risk, before acting directly on the patient has grown along with the technological development in health … Read More >>

5 – Theranostics – Here we explore the combined use of MagnetoMotive Ultrasound, Hyperthermia and Nanomedicine. Our techniques involves excitation of a target or labeled medium with magnetic nanoparticles by applying an alternating magnetic field and measuring the displacement and temperature of the internal structures of medium by acoustic techniques … Read More >>

6 – Neuromodulation – In the field of focused ultrasound, which encompassing the study of especific transducers for applications in brain disorders, cancer immunotherapy and veterinary medicine, our team focuses to develop the ultrasound transducer, a robotic neuronavigate system and protocols for neurotherapeutic techniques … Read More >>
