In this study, a dual modality imaging system which utilises the magnetic flux density measurements, acquired using Magnetic Resonance Current Density Imaging (MRCDI) techniques, and the surface potential measurements, obtained from conventional Electrical Impedance Tomography (EIT) techniques, to reconstruct high resolution absolute conductivity images. An iterative algorithm is developed to m...

We propose a new scanhead design for combined ultrasound (US)/photoacoustic (PA) imaging that can be applied to dual-modality microscopy and biomedical imaging. Both imaging modalities employ the optical generation and detection of acoustic waves. The scanhead consists of an optical fiber with an axicon tip for excitation, and a microring for acoustic detection. No conventional piezoelectric de...

Using functional magnetic resonance imaging (fMRI), we measured brain activity of human participants while they performed a sentence congruence judgment task in either the visual or auditory modality separately, or in both modalities simultaneously. Significant performance decrements were observed when attention was divided between the two modalities compared with when one modality was selectiv...

RGB-Infrared (IR) person re-identification aims to retrieve person-of-interest from heterogeneous cameras, easily suffering large image modality discrepancy caused by different sensing wavelength ranges. Existing works usually minimize such aligning distribution of global features, while neglecting deep semantics and high-order structural relations within each class. This might render the misal...

Biocompatible dual-modality imaging nanoprobes were synthesized by the electrostatic assembly of poly(γ-glutamic acid)[Gd-DTPA] and chitosan[IRDye800] and applied for the imaging of immune cells (phagocytic) and cancer cells (non-phagocytic).

A general approach involving a solvothermal method was developed to synthesize a series of silicate nanoshells (<100 nm) where both Gd silicate and Gd silicate:Eu nanoshells were further demonstrated to exhibit dual-modality MRI and optical imaging functions.
