Characterizing Muscle and Subcutaneous Adipose Tissue Imaging Phantoms for NMR Application
Medical imaging techniques are being increasingly used to derive quantitative information, requiring a new type of imaging phantom for validation. Here, we describe the T2 relaxation properties of an emulsified two-phase imaging phantom for validating a nuclear magnetic resonance (NMR) sensor for …

Fractional derivative models and their use in the characterization of hydropolymer and in-vivo breast tissue viscoelasticity
… these parameters for simulated and experimental imaging phantoms and to estimate them for normal and cancerous in-vivo breast tissues. After a detailed presentation of the processing algorithm and discussion of its performances, we analyze the KVFD parameter values in simulated and experimental …

Multi Array, Conformable Ultrasound Patch for Soft Tissue Imaging
Medical ultrasound imaging is a rapidly growing field due to its safety and affordability when compared to other imaging modalities such as MRI and X-Ray. Ultrasound transducers are made in various configurations from dense 2-D arrays for volumetric imaging to single element needle like transducers …

Development and Applications of Laminar Optical Tomography for In Vivo Imaging
Laminar optical tomography (LOT) is an optical imaging technique capable of making depth-resolved measurements of absorption and fluorescence contrast in scattering tissue. LOT was first demonstrated in 2004 by Hillman et al [1]. The technique combines a non-contact laser scanning geometry, similar …

Piezoelectric MEMS for Energy Conversion in Biomedical Devices
… emitted ultrasound signals from photoacoustic imaging applications. Tests on imaging phantoms with target dimensions ranging from 0.3 mm to 0.7 mm allow the PMUTs to characterize the corresponding frequency response and reconstruct images with comparable resolution and quality by integrating …

Bilateral Ortohogonality Generative Acquisitions Method for Transmit Field Inhomogeneity Correction in Magnetic Resonance Imaging
Ultra-high field (>7T) magnetic resonance imaging (MRI) systems result in higher intrinsic signal to noise ratio compared to the lower field systems and have been previously utilized for acquisition of high-resolution images and reducing scan time. However, transmit field inhomogeneity of …
