  • Research on the three-region multipath pulse detecting system

    A TCM pulse detecting system consistent with pulse feeling of “three regions and nine divisions” in TCM is introduced in the article, including the design and features of three-region multipath pulse sensor, design of multipath pulse amplifier and design of multipath pulse analytical system. The article also introduces contents directly related with the pulse detecting system, such as associativity among pulse taking pressure at three regions, detection method of long and short pulse, detection method of width of pulse and safety in increasing pressure. It is believed that the three-region multipath pulse detecting system can simulate the pulse feeling method of “three regions and nine divisions” in TCM. The system can collect more pulse information and make objective description about width and length of different kinds of pulses, providing effective and reliable test facilities and method for breakthrough in TCM diagnosis and teaching patterns, and modernization and internationalization of TCM.

  • Automatic retinal vessel tortuosity measurement

    Retinal vessel tortuosity measurement is the reliable method used as an opthalmological diagnostic tool. For example, Retinopathy of Prematurity (ROP), this disease can be characterised by the increasing in vascular dilation and tortuosity. This paper proposes a method of how to measure and define tortuous scale using the mean curvature. The tortuosity measurement is calculated base on the radius derive from chord in each curve of the blood vessel. The result obtains from this method can set the standard of tortuosity grading in the retinal vessel. The advantage of this method is to reduce the error in tortuosity calculation, which cause by the low quality image of the retinal vessel.

  • 1.5 dimensional circular pattern filter for multiscale lung nodule detection

    The work presented is an important step in computerized lung nodule detection. The existing schemes proposed in the literature are generally two-step procedures, i.e., segmentation of suspicious areas followed by a differentiation of nodules from lung and chest structures. The algorithms in these schemes for the suspicious area segmentation are all based on 2-D matched filtering techniques which may not be robust in the situations where lung structures overlap with nodules. The 1.5-D circular pattern filter proposed in this paper uses a grouped local gradient characteristics method which is insensitive to overlapped structures, but sensitive to a pre-defined shape, such as circular area. A set of multiscale filters combined with a multiscale stability analysis provides a very effective method for detection of lung modules of different sizes.

  • MPRS: Medipix parallel readout system for angiography digital imaging

    A fast readout system for the Medipix2 pixel chip has been developed for digital angiography applications to allow real time X-ray imaging of contrast media flowing in blood vessels. The readout system is designed to acquire data coming from the 32-bit Medipix2 parallel port of a maximum of eight chips at a rate of 25 frames per second. The readout electronics is peripheral component interconnect (PCI) bus-based and consists of two boards: the motherboard directly interfacing the chip for settings and data flow and the PCI board linking the motherboard to the bus. With parallel readout, a transfer rate of up to 64 MByte/s has been achieved.

  • An Adaptive Ray-Shooting Model for Terminations Detection: Applications in Neuron and Retinal Blood Vessel Images

    2D and 3D termination points are very good seeding point choices for the tree- like structure reconstruction in neuron or retinal blood vessel images. Previously, a ray-shooting model was proposed to detect the termination points in fluorescence microscopy images of neurons, by analyzing the pixel intensity distribution of the neighborhood around the neuron termination candidates. However, the length of the shooting rays and the number of z-slices taken into account in the existing ray-shooting model are fixed empirical number. This ray-shooting model cannot handle the diameter variation of neuron branches. In this paper, we propose an adaptive ray-shooting model to detect the terminations of neurons or retinal blood vessels by changing the length of the shooting rays according to their local diameters. The local diameter is estimated by the Multistencils Fast Marching Method (MSFM) in combination with the Rayburst sampling algorithm. We train a support vector machine (SVM) classifier to classify the termination points and non-termination points, by using the pixel intensity distribution features extracted by the adaptive ray- shooting model. Compared with the previous work, the experimental results on multiple neuron datasets and retinal blood vessel datasets show that our method significantly improves the detection accuracy rate by about 10% in challenging datasets.

  • Nanoparticles and ultrasound for delivery of model macromolecular anti-cancer drugs in tumors

    Penetration of macromolecular anti-cancer agents from blood into tumor cells is poor due to the physiological barriers: tumor capillary wall, interstitium, and cancer cell membrane. We proposed to use laser- or ultrasound-induced cavitation to enhance anti-cancer drug delivery through these barriers. Interaction of ultrasound with exogenous nanoparticles with certain acoustic properties may provide cavitation selectively in tumors and, therefore, may provide safe and efficient delivery of anti-cancer drugs in cancer cells without damage to normal tissues. In this paper, we studied enhanced delivery of model macromolecular anti-cancer drugs with ultrasound-induced cavitation in mice bearing human colon (KM20) and breast (MCF-7) tumors. Fluorescent rhodamine-dextrans of different molecular weight (10, 70, and 2,000 kDa) served as model drugs simulating antisense oligonucleotides, antibodies, and genes, respectively. Immunohistochemical staining of tumor vasculature with CD31 was used to visualize tumor blood vessels. Our studies demonstrated enhanced penetration of the drugs from blood vessels into tumor interstitium when ultrasound was applied in combination with polymer nanoparticle injections. Our results suggest that this drug delivery technique can potentially be used for efficient cancer chemo- and biotherapy.

  • A Combining Method for Tumors Detection from Near-infrared Breast Imaging

    This paper introduces the new qualitative and quantitative methods, which can diagnose breast tumors. Qualitative methods include blood vessel display inside and outside of pathological changes part of breast, display of equivalent pixel curves at the part of pathological changes and display of breast tumor image edge. Accordingly, three feature extraction operators are proposed, i.e. the combination operators of anisotropic gradient and smoothing operator, an improved Sobel operator and an edge sharpening operator. Furthermore, quantitative diagnostic approaches are discussed based on blood and oxygen contents according to abundant clinical data and pathological mechanism of breast tumors. The results of clinic show that the methods of combining qualitative and quantitative diagnose are effective for breast tumor images, especially for early and potential breast cancer

  • A novel retinal vessel extraction method based on dynamic scales allocation

    Automatic extraction of retinal vessels is significant for diagnosis of eye diseases. Currently, the automatic extraction of the vessels in the retinal images with very low contrast and various widths is a bottleneck. In this paper an effective retinal blood vessel extraction method to detect fine vessels more accurately was presented. The contribution of this work is that a novel dynamic scale allocation scheme of the matched filter was proposed. The whole image is divided into sub-blocks. The histogram of each sub-block is fitted by Gaussian function whose fitting parameters are used to select the scales. Compared with the existing blood vessel extraction using uniform multiscale matched filter, the proposed method detects many fine vessels drowned by noise and has good width estimation.

  • Extraction of Blood Vascular Network for Development of an Automated Diabetic Retinopathy Screening System

    Segmentation of vascular structures of retina for implementation of Clinical diabetic retinopathy decision making systems is presented in this paper. As retinal vascular structure is with thin blood vessels, prediction accuracy is highly dependent upon the segmentation and preprocessing schemes. Complex GSZ shock filters have been used for noise suppression and edge enhancement. Binarization algorithms are used to achieve the segmentation of vascular structures of the retina. It has been observed that the combination of shock filter and Binarization provides better segmentation results compared to morphological and region growing methods.

  • Biological mechanisms of acoustically-induced hemostasis

    Several mechanisms are postulated to be responsible for acoustically-induced hemostasis. Both mechanical and thermal aspects of ultrasound energy are thought to play a role. Thermal effects may be important when tissue shrinkage is necessary to close a bleeding site. A moderate temperature rise may also accelerate clotting when hypothermia and coagulopathy is present. Tissue welding via collagen restructuring may be promoted via a thermal effect. The mechanical effects of streaming and radiation pressure may assist in stopping the flow of blood out of a wound and, if directed properly, may cause insertion of blood vessel wall material into a breached region to plug the hole, and aid the natural clotting mechanism. Streaming may provide shearing forces on platelets, facilitating their activation for subsequent aggregation and adhesion to the vessel wall. Cavitation may produce tissue disruption that exposes collagen and tissue factors to platelets thus assisting in triggering clotting. These mechanisms are discussed, and supportive evidence given.
