Photoacoustic imaging (PAI) is an emerging biomedical imaging modality that is based on
optical absorption contrast, capable of revealing distinct spectroscopic signatures of tissue at …

The rapid advancements in the areas of biosensors, soft robotics, and tissue engineering
increased the demand for hydrogels (gels) and their composites. This is aided by the ease of …

A small and low cost extrinsic Fabry-Perot (FP) fiber low-frequency acoustic pressure sensor
(EFPAS) based on polydimethylsiloxane (PDMS) diaphragm is proposed. The EFPAS is …

High-frequency ultrasound imaging can provide exquisite visualizations of tissue to guide
minimally invasive procedures. Here, we demonstrate that an all-optical ultrasound …

Ultrasound imaging is widely used to guide minimally invasive procedures, but the
visualization of the invasive medical device and the procedure's target is often challenging …

Medical instrument detection is essential for computer-assisted interventions, since it
facilitates clinicians to find instruments efficiently with a better interpretation, thereby …

Ultrasound guidance is becoming standard practice for needle‐based interventions in
anaesthetic practice, such as vascular access and peripheral nerve blocks. However …

Purpose This scoping review covers needle visualization and localization techniques in
ultrasound, where localization-based approaches mostly aim to compute the needle shaft …

Photoacoustic imaging has shown great potential for guiding minimally invasive procedures
by accurate identification of critical tissue targets and invasive medical devices (such as …

Purpose Accurate placement of the needle is critical in interventions like biopsies and
regional anesthesia, during which incorrect needle insertion can lead to procedure failure …
