Retinal images can be used for helping ophthalmologist to diagnose the eye diseases, and glaucoma, hypertension, coronary heart diseases and so on, so it's very important. The most important content of this article is a new structural feature for retinal registration. There are many methods of retinal image registration; some are also used by this time. Lots of methods used the main bifurcation points...
3D reconstruction of image sequences is an important application in computer graphics and image processing, especially in biomedical engineering. 3D reconstruction of elastin second harmonic generation (SHG) sequences images can offer much more spatial structure information to improve the diagnostic accuracy significantly. In the paper, we designed a reconstruction pipeline of normal scar samples...
With the increasing volume of container transport, the international community pay more and more attention to container security. This paper investigates the new concept, key function and key technologies available of the secure and smart container. Especially on the base of application and survey, this paper carries on the research of standard system. Under the current standard system frame, it works...
In this paper, we present three second-order finite element methods solving Maxwell’s equations when metamaterials are involved. The first method is based on integral-differential equations transformed from the governing equations; the other two methods solve the original governing differential equations. Numerical results are presented for the last two methods.
this paper introduces a novel approach of stiffness measurement based on force and vision sensing for tissue diagnosis. The developed probe is mainly composed of a force sensor and an image acquisition unit capable of obtaining contact area of probe-soft tissue interaction. By measuring the change of diameter of contact area during indentation test, the indentation depth can be determined. The stiffness...
This paper introduces a new and low-cost tissue stiffness simulation technique for surgical training and robot-assisted minimally invasive surgery (RMIS) with pseudo-haptic feedback based on tissue stiffness maps provided by rolling mechanical imaging. Superficial palpation and deep palpation pseudo-haptic simulation methods are presented. Although without expensive haptic interfaces users receive...
this paper presents a smart, novel stiffness probe capable of detecting the abnormality within soft tissue during minimally invasive surgery. The proposed probe is based on force-contact area feedback of target soft tissue. A prototype for validating the concept was developed. The prototype comprises a force/torque sensor, a probe with a transparent round head and a digital camera capturing contact...
In this paper, we use quantile regression estimate and data from 2001 to 2003 to analyze the investment style for different types of open-end funds in China. The main result is that the investment style of growth funds, balance funds and value funds in China share some commonality. They all prefer investing in large-cap, mid-cap growth stocks and small value stocks. Value fund prefers value stocks...
This paper presents a novel miniaturized force-indentation depth (FID) sensor designed to conduct indentation on soft tissue during minimally invasive surgery. It can intra-operatively aid the surgeon to rapidly identify the tissue abnormalities within the tissue. The FID sensor can measure the indentation depth of a semi-spherical indenter and the tissue reaction force simultaneously. It make use...
