“…Lu et al proposed a low-cost and shadow-free IVOCT catheter based on a miniaturized propeller that does not need an electrically driven scanning device [ 63 ]. Wang et al firstly combined OCT catheter with fiber Bragg grating (FBG) to reconstruct the vascular shape and bending direction in real time [ 64 ]. The FBG-OCT catheter provides a visual image of the vessel, providing information for plaque measurements, blood flow velocity, and blood pressure.…”

Blood vessels are one of the most essential organs, which nourish all tissues in our body. Once there are intravascular plaques or vascular occlusion, other organs and circulatory systems will not work properly. Therefore, it is necessary to detect abnormal blood vessels by intravascular imaging technologies for subsequent vascular treatment. The emergence of lasers and fiber optics promotes the development of intravascular imaging and treatment. Laser imaging techniques can obtain deep vascular images owing to light scattering and absorption properties. Moreover, photothermal and photomechanical effects of laser make it possible to treat vascular diseases accurately. In this review, we present the research progress and applications of laser techniques in intravascular imaging and treatment. Firstly, we introduce intravascular optical coherent tomography and intravascular photoacoustic imaging, which can obtain various information of plaques. Multimodal intravascular imaging techniques provide more information about intravascular plaques, which have an essential influence on intravascular imaging. Secondly, two laser techniques including laser angioplasty and endovenous laser ablation are discussed for the treatment of arterial and venous diseases, respectively. Finally, the outlook of laser techniques in blood vessels, as well as the integration of laser imaging and treatment are prospected in the section of discussions.

“…To better understand physical information of the blood vascular, such as blood pressure, blood flow, and vascular stenosis, Wang et al combined an OCT catheter with FBG to acquire shape parameters and OCT images in real time to reconstruct the vascular model [ 67 ]. Kang et al demonstrated an all-fiber-based proximal-driven OCT catheter, in which the lens can directly be assembled with the commercial single-mode fiber [ 68 ].…”

Advancements in robotic surgery help to improve the endoluminal diagnosis and treatment with minimally invasive or non-invasive intervention in a precise and safe manner. Miniaturized probe-based sensors can be used to obtain information about endoluminal anatomy, and they can be integrated with medical robots to augment the convenience of robotic operations. The tremendous benefit of having this physiological information during the intervention has led to the development of a variety of in vivo sensing technologies over the past decades. In this paper, we review the probe-based sensing techniques for the in vivo physical and biochemical sensing in China in recent years, especially on in vivo force sensing, temperature sensing, optical coherence tomography/photoacoustic/ultrasound imaging, chemical sensing, and biomarker sensing.

Wideband dissipative soliton is generated in a passively mode-locked cavity by optimizing the distribution of chromatic dispersion and gain ltering in cavity. The maximal 3 dB bandwidth of 61.1 nm is obtained. The corresponding pulse width is compressed to 222 fs with chirp, which could be further compressed to 42 fs according to the Fourier transform limitation. The signal-to-noise ratio is 80.3 dB.The single pulse energy is 0.18 nJ. The dynamics process is investigated by dispersive Fourier transformation during the building-up. The simulation investigation on dissipative soliton formation is provided according to the modi ed nonlinear Schrödinger equation, which are relatively consistent with the experiment. The results demonstrate that a weak normal net dispersion close to zero and e cient gain bandwidth are critical to the formation of wideband dissipative soliton.
