  • Three-dimensional reconstruction of implanted aortic stents using computed tomography

This CT data was segmented and the vessel structures as well as the stent were reconstructed. The visualization using the AVS software allows a fast and comfortable manipulation and display of the calculated 3D objects. Even the integration of the original CT data and animations are possible. These 3D reconstructions enable the accurate assessment of the vessel and stent geometry, the stent location relative to stenosis, dissection, plaque or calcification and help to identify potential stent displacements. Thus, spiral-CT has become a comparative and competitive modality to conventional angiography in the pre-interventional planning and control of stent placement.

  • MPRS: Medipix parallel readout system for angiography digital imaging

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.

  • Improving left ventricular border recognition using probability surfaces

    The authors present a method for automating the generation of search targets used in finding borders of the left ventricle (LV) from digital-subtraction angiography (DSA) images and thus further automating LV-border determination. This method uses a large clinical database of LV borders to generate a probability surface of expected border locations. A composite image of all observed border points is used to create a set of extraction lines that is overlaid on the LV of interest. Border points are found by using a dynamic search on the density matrix formed by extracting pixel values at the points defined by the extraction matrix. User interaction is only needed to define the valve plane, confirm the final border, and make corrections if needed. LV contours then be used to find end-diastole and end-systole volume and ejection fraction.<<ETX>>

  • Motion-compensated iterative sparse data reconstruction for interventional 3-D coronary artery imaging

    Three-dimensional (3-D) reconstruction of the coronary arteries from a rotational X-ray angiography sequence can support diagnosis of coronary artery disease, treatment planning, and intervention guidance during catheter interventions. 3-D reconstruction enables quantitative vessel analysis, including vessel dynamics from a time-series of reconstructions. This contribution presents a method for reconstructing coronary arteries with high contrast and high level of detail. It employs an iterative reconstruction algorithm in combination with projection-based motion compensation. An efficient implementation using a graphics processing unit delivers reconstruction times close to clinically acceptable values. Reconstructions from clinical human cases, acquired on an interventional C-arm system, are presented. Excellent image quality is achieved.

  • Applications of the median filter to digital radiographic images

    It is well known that Digital Subtraction Angiography (DSA) images suffer from the influence of noise. Linear filters have been applied to DSA images with some success but are known to introduce image degradation. It is particularly important that edge details be preserved in DSA images since the outline of vessels frequently contains the diagnostically useful information. The non- linear median filter possesses the property of removing spurious noise while preserving edge detail in an image. In the work presented here the difficulties of applying a median filter in two dimensions to the cartesian matrix of a typical image are investigated. The development of a suitable noise-added test image for this purpose is presented.

  • Computer simulation of blood flow using short te magnetic resonance angiography

    Using computer simulation of pulsatile blood flow and magnetic resonance angiography (MRA), we investigated the hemodynamic factors leading to the formation and evolution of 1) atherosclerotic plaque in carotid arteries, and 2) aneurysms in the abdominal aorta. Phantom and patients were imaged by MRA, color Doppler and/or digital subtraction angiography (DSA). Computer modelling was carried out by finite element analysis to solve the Navier-Stokes equation. In the analyzed vessels, voxels representing pathology were digitally removed. Local wall shear stress and pressure were also calculated as a function of a cardiac cycle. There was general agreement between MRA, color Doppler, DSA and computer simulation in both phantom and in-vivo experiments. In MRA, the best results were achieved by short TE, thin slice 2D “time-of-flight” technique, which was least susceptible to the changes in velocity profiles, and best correlated with Doppler and computer simulation. The hemodynamic information obtained from analyzed carotid arteries predicted that during late systole, flow separation exists at the exact locations from where the plaque voxels were removed. We were also able to predict the location of abdominal aortic aneurysm and its evolution toward the distal vessel intima. In conclusion, MRA accurately depicted flow disturbances, and computer simulation of blood flow proved to be a good predictor of the development of vascular pathology.

  • Weighted Local Variance-Based Edge Detection and Its Application to Vascular Segmentation in Magnetic Resonance Angiography

    Accurate detection of vessel boundaries is particularly important for a precise extraction of vasculatures in magnetic resonance angiography (MRA). In this paper, we propose the use of weighted local variance (WLV)-based edge detection scheme for vessel boundary detection in MRA. The proposed method is robust against changes of intensity contrast of edges and capable of giving high detection responses on low contrast edges. These robustness and capabilities are essential for detecting the boundaries of vessels in low contrast regions of images, which can contain intensity inhomogeneity, such as bias field, interferences induced from other tissues, or fluctuation of the speed related vessel intensity. The performance of the WLV-based edge detection scheme is studied and shown to be able to return strong and consistent detection responses on low contrast edges in the experiments. The proposed edge detection scheme can be embedded naturally in the active contour models for vascular segmentation. The WLV-based vascular segmentation method is tested using MRA image volumes. It is experimentally shown that the WLV- based edge detection approach can achieve high-quality segmentation of vasculatures in MRA images.

  • Comparative study of MSCTA with DSA in the blood supply of meningiomas

    Evaluation of multi-slice CT angiography (MSCTA) and digital subtraction angiography (DSA) was made through the comparison of the two methods in the detection of the blood supply of meningiomas, providing further clues for improved application of MSCTA and DSA in the blood supply of meningiomas. MSCTA is more advantageous in the depiction of three-dimensional relationships between the tumor and peripheral vessels and skull. And, compared to DSA, MSCTA is noninvasive, faster and cheaper.

  • Region Growing within Level Set Framework: 3-D Image Segmentation

    We present a novel level set framework combined with seeded region growing algorithm for the automatic segmentation of complicated structures from volumetric medical images. Level set evolution methods combine global smoothness with the flexibility of topology changes and offer significant advantages over conventional statistical classification while region growing algorithms provide pretty fast classification inside the target regions. The driving application is the segmentation of 3D human cerebrovascular structures from magnetic resonance angiography (MRA), which is known to be a very challenging segmentation problem due to the complexity of vessels geometry and intensity patterns. The results demonstrate the potential of our approach. This framework should also be suitable for other 3D image segmentation that the region of interest to be segmented has a relatively large size in width, height or both

  • The implementation of the evaluation system of major equipment procurement in a medical institution

    This paper presents the evaluation system of major equipment procurement in a medical institution. It provides the integrated resources for the hospital chief administrator and staff about need motivation and background, situation analysis, estimated production capacity, profit, payback period, and related costs. Most importantly, the conclusions and suggestions from this medical institution point of view could be shown. Through this platform the head of institutional decision-making may consent to purchase them or not. Besides, the system can also indicate the availability rate about medical equipment after arriving the institution during some periods. The results show the feasibility to evaluate the performance of instruments, especially in expensive modalities such as CT, Angiography X-ray machines and Ultrasounds. By means of the evaluation system, the medical personnel can facilitate the supervision and management of instruments and equipment as well, and further create the value of significant assets in the medical institution.
