Shenyang Bus Waiting Booth Design Research And The Practice Exploration

Volume rendering of medical data makes resample and reconstruction with the medicalrule data sets using modern computing image processing technology and displays2D，quasi-3Dand3D images on a computer monitor, which is an effective means for a doctor to find outinternal information of a patient. Visualization technology has always been one of the centralissues in computer research and played a very important role in virtualization field.The topic in this paper can be classified into the intersection field between computer andmedicine. With the development of computer hardware and software technology, hardwarecalculation has been continually upgraded in accordance with the rate in Morgan’s law(Thenumber of transistors contained on IC will double about every18months, as well as thecapability will also double, while the price will not change.) The CPU in a common PCnowadays has developed to dual even quad core processors, and the memory has increased toover4GB. The task originally only completed by a graphics workstation can be moved to acommon computer. Meanwhile, the progress of computer software has grown towarddevelopment convenience. All of the above mentioned provides not only good facilities toachieve real-time interactive3D image reconstruction system, but also provides the basis for themore complex image reconstruction based on depth information raised in this paper.This paper first systematically reviewed the development of medical image3Dreconstruction progress home and abroad, and then proposed a3D image reconstruction based ondepth information and3D segmentation model. It also developed a completed medical imageprocessing system with good human-computer interaction, which consists of perfect2D sliceimage processing subsystem, quasi-3D image processing subsystem, and3D imagereconstruction subsystem (including3D surface rendering,3D volume rendering, and3Dsegmentation). Excellent human-computer interaction technology allows a doctor the good andreal-time operation with all the images with only mouse and keyboard, which provides doctorsintuitive and convenient visual information of preoperative diagnosis.We innovated in three aspects here. First, we made full use of the advantages of PCcomputer hardware technology to add depth information into the traditional volume renderingmethod, and sampled and reconstructed according to the depth information. Which allowsdoctors to constantly adjust depth values with mouse, and "poke" image layer by layer, untilobserve the internal hidden organization. Second, excellent human-computer interaction designwhich penetrates into the interactive display of2D, quasi-3D, and3D images allows doctors toadjust all of the above images with only mouse (e.g. zoom, rotate, move, etc.). It also allowsdoctors to finish the operations such as adjusting window width and window level of the image,access to image coordinates and gray value, and measurement of the length and angle, etc. Third, the completed medical imaging system developed can meet the needs of clinician’s diagnosisfrom all aspects such as the input, display, reconstruction, manipulation and output of medicalimage in DICOM format.
