Increasingly wider availability of biomedical imaging modalities, such as X-ray computed tomography (CT), magnetic resonance imaging (MRI), ultrasonic imaging, positron emission tomography (PET), single-photon emission computed tomography (SPECT), and optical imaging, have led to significant progresses in both biomedical research and clinical practice. Advancements in imaging technology and ima...

In magnetic resonance imaging (MRI), methods that use a non-Cartesian (e.g. spiral) sampling grid in k-space are becoming increasingly important. Reconstruction is usually performed by resampling the data onto a Cartesian grid. In this paper we compare the standard approach (gridding) and an approach based on an implicit discretisation. We show that both methods can be solved efficiently with t...

In this paper most of the important telemedicine applications with optical fiber sensor were introduced, and they included two techniques of using optical fiber sensors with monitoring and treating patients remotely through the operation. Optical sensors with MRI compatibility have been used in these two fields through catheter and biopsy techniques. This survey is the first one in which the op...

This communication presents the first Gd(III)-based T1 MRI contrast agent, o-MeHgGad, for noninvasive visualization of CH3Hg(+). o-MeHgGad showed a relaxivity enhancement of 62% in the presence of 1 equiv. of CH3Hg(+). Moreover, a noticeable contrast enhancement was recorded in the liver, kidney, and intestine of mice exposed to CH3Hg(+). Thus, the newly designed contrast agent has the potentia...

The earliest stage of breast cancer, ductal carcinoma in situ (DCIS), is a remarkably heterogeneous disease with diverse molecular and prognostic subtypes. Mouse models of breast cancer offer an effective experimental framework in which to investigate DCIS, and biomedical imaging can provide potential insights into the biology of these models. In this study, we develop a high resolution, multi-...

Biomedical imaging techniques are applied to observe the hidden process of human articulation. We propose a new approach for obtaining a typical image for a phoneme’s articulation. We use vocal tract images captured using dynamic MRI, and by considering image spatial characteristics (intensities), we calculate the average of different instances of phoneme articulation. The obtained image presen...
