In this review, the roles of detectors in various medical imaging techniques were described.
Ultrasound, optical (near-infrared spectroscopy and optical coherence tomography) and …

Simultaneous visualization of the teeth and periodontium is of significant clinical interest for
image-based monitoring of periodontal health. We recently reported the application of a dual …

In photoacoustic tomography (PAT) systems, the tangential resolution decreases due to the
finite size of the transducer as the off-center distance increases. To address this problem, we …

Transcranial ultrasound imaging (TUI) is a diagnostic modality with numerous applications,
but unfortunately, it is hindered by phase aberration caused by the skull. In this article, we …

Electronic scanning of two-dimensional (2-D) arrays and mechanical or freehand scanning
of one-dimensional (1-D) arrays have been mostly utilized for conventional three …

As a safe and convenient imaging technology in clinical routine diagnosis, ultrasound
imaging can provide real-time 2D images of internal tissues and organs. To realize real-time …

2-D sparse arrays may push the development of low-cost 3-D systems, not needing to
control thousands of elements by expensive application-specific integrated circuits (ASICs) …

Arteriosclerosis results from lipid buildup in artery walls, leading to plaque formation, and is
a leading cause of death. Plaque rupture can cause blood clots that might lead to a stroke …

Real-time 3D ultrasound (US) imaging has attracted more attention since it can display
spatial 3D images of tissues and organs in real time to provide important information for …

Transcranial ultrasound imaging is a suitable technology for diagnosis of strokes as it is
safe, portable, relatively inexpensive and available in emergency medicine services …
