In order to solve the problems of poor image quality, loss detail information and excessive brightness enhancement during in low light environment, we propose a low-light algorithm based on improved multi-scale Retinex Artificial Bee Colony (ABC) optimization this paper. First all, makes two copies original image, afterwards, irradiation component is obtained by used structure extraction from texture via relative total variation for first combines it with obtain reflection which are...
We report a new type of heterogeneous nanoparticles (NPs) composed heavily doped semiconductor domain (Cu2-xSe) and metal (Au), which exhibit broad localized surface plasmon resonance (LSPR) across visible near-infrared (NIR) wavelengths, arising from interactions between the two nanocrystal domains. demonstrate both in vivo photoacoustic imaging vitro dark field imaging, using LSPR Cu2-xSe-Au hybrid NPs to achieve contrast at different wavelengths. The high depth achieved, up 17 mm, shows...
Photoacoustic (PA) imaging, as a fast growing technology that combines the high contrast of light and large penetration depth ultrasound, has demonstrated great potential for molecular imaging cancer. However, PA orthotopic brain tumors is still challenging, partially due to limited options insufficient sensitivity available probes. Here, direct formation single‐layer (S‐MoS 2 ), few‐layer (F‐MoS multi‐layer (M‐MoS ) nanosheets by albumin‐assisted exfoliation without further surface...
By localizing microbubbles (MBs) in the vasculature, ultrasound localization microscopy (ULM) has recently been proposed, which greatly improves spatial resolution of (US) imaging and will be helpful for clinical diagnosis. Nevertheless, several challenges remain fast ULM imaging. The main problems are that current methods used to implement imaging, e.g., a previously reported method based on sparse recovery (CS-ULM), suffer from long data-processing time exhaustive parameter tuning...

The analysis of robot inverse kinematic solutions is the basis control and path planning, great importance for research. Due to limitations analytical geometric methods, intelligent algorithms are more advantageous because they can obtain approximate directly from robot's positive equations, saving a large number computational steps. Particle Swarm Algorithm (PSO), as one algorithms, widely used due its simple principle excellent performance. In this paper, we propose an improved particle...

Ultrasound localization microscopy (ULM) overcomes the acoustic diffraction limit by localizing tiny microbubbles (MBs), thus enabling microvascular to be rendered at sub-wavelength resolution. Nevertheless, obtain such superior spatial resolution, it is necessary spend tens of seconds gathering numerous ultrasound (US) frames accumulate MB events required, resulting in ULM imaging still suffering from trade-offs between quality, data acquisition time and processing speed. In this paper, we...

Abstract Background Radiation therapy delivers precise doses to tumors, but accurately measuring internal tissue remains a challenge. Current methods, such as ionization chambers and radiographic films, rely on external measurements, which cannot provide direct, in vivo dose feedback. X‐ray acoustic computed tomography (XACT) was developed generate thermoacoustic signals when x‐rays deposit energy into water or tissue, enabling the reconstruction of distribution patterns through signals....

Super-resolution ultrasound (SR-US) imaging technique breaks the diffraction limit and can image microvascular structure. However, temporal resolution of SR-US is limited because a long data acquisition time required to accumulate enough microbubbles.

Photoacoustic tomography (PAT) is an emerging biomedical imaging technology that can realize high contrast with a penetration depth of the acoustic. Recently, deep learning (DL) methods have also been successfully applied to PAT for improving image reconstruction quality.
