The relation of metabolic electrolyte disturbance and multi-organ functional disturbance on severe actue mountain sickness patients / 中华内分泌代谢杂志

Electrolyte disturbance was prominent in patients with severe acute mountain sickness. In these patients hypoxia caused water and salt retension together with vasoactive substances and excessive free radicals might play important roles in the development of multiple organ dysfunction syndrome (MODS). More attention should be given to electrolyte monitoring in dealing with these severe mountain sickness in field.

Study of 3D visualization methods on PACS workstation / 生物医学工程学杂志

Based on a discussion on PACS and the way its image workstation obtains scanned sequential images, this paper presented a method of 3D surface construction and visualization on PACS workstation. Guest/Server structure was used between PACS application entities. Image storing and transmission were realized by service classes established by DICOM standards. Relation database was used to arrange the stored sequential images. Image workstation transformed the sequential images obtained from PACS net into volume data field. 3D reconstruction and rendering results were obtained by using surface-rendering and volume-rendering methods, which made the 3D construction results acquire vivid 3D structure details of high fidelity and strong sense of reality. 3 sets of application results were also presented in this paper.

Registration and 3D rendering of serial tissue section images / 生物医学工程学杂志

It is an important morphological research method to reconstruct the 3D imaging from serial section tissue images. Registration of serial images is a key step to 3D reconstruction. Firstly, an introduction to the segmentation-counting registration algorithm is presented, which is based on the joint histogram. After thresholding of the two images to be registered, the criterion function is defined as counting in a specific region of the joint histogram, which greatly speeds up the alignment process. Then, the method is used to conduct the serial tissue image matching task, and lies a solid foundation for 3D rendering. Finally, preliminary surface rendering results are presented.
