The study mentioned a curing equipment with UV LED array based on pyroelectric sensor and AP3706, which is based on the primary side control circuit so that it can complete the LED array constant voltage constant current output.the light source drive can output the constant voltage and constant current. The sensing signal processing signal integrated circuit BISS0001 as the pyroelectric sensor amplifier circuit as core, with relay making up the protection module of curing device. The experimental results show that, the curing equipment can realize the stable and homogeneous UV output, and when a human body in front of LED, the array will disabled to keep the human body away from damage UV induced.

Heart Sounds are important things in the human body that can deliver information related to the heart condition. However, a recorded signal such as PCG and ECG that getting through Audicor still contain unexpected components or noise while the recording process happens it makes the result data from Audicor cannot directly use to recognize the condition of the heart. This research presents signal processing and data analysis to suppress the noise of the heart sounds that getting while the process of recording data happens. The cleaned heart sound will be processed in feature extraction by using FFT and PCA that capable to produce the feature both of the normal and abnormal heart sounds. For the normal case, we get the data from some healthy volunteers recorded by using Audicor. While the abnormal heart sound we focus to observe the data that contain Ventricular Septal Defect (VSD) that getting from a partner hospital.  As a result, feature both normal and abnormal heart sounds can be separated.

After introduction to medical imaging, virtual reality (VR), and VR surgical simulation, the paper overviews our long-term efforts in human body modeling and development of VR-based applications for brain intervention. It describes construction, features, and applications of anatomical, functional, and vascular brain atlases. It also presents VR-based applications developed for stereotactic and functional neurosurgery (NeuroPlanner, NeuroBase, and BrainBench), interventional neuroradiology (NeuroCath and tele-NeuroCath), and tumor stereotaxis (VIVIAN). Finally, a vision of the future surgery (the DOTELL environment) is presented.

The Impact

This chapter provides a brief introduction to the various fundamentals and concepts related to the basics of the biomedical image processing. Medical imaging processing comprises various techniques and processes that are used to create images of human body for clinical purposes and medical procedures for the purpose of diagnosis or examination of disease. Digital image processing along with its suitable components and computer-simulated algorithms are implemented using computers to perform the image analysis of digital images. The study of normal anatomy and physiology of human body is made as a part of diagnosis process. Though medical imaging of various organs and tissues can be performed for medical examination purposes, the impact of digital images on modern society is tremendous and image processing has become a critical component of science and technology related to the biomedical image processing.
