该提案要求资金购买Silicon Graphics，Inc.4D240GTX 配备Voxel View软件的图形超级计算工作站，由 这一图像处理系统将使多- 由联邦资助的研究人员组成的学科小组，具有强大的 协作关系，访问昂贵的最先进的计算机图形 脑图像的三维体绘制技术。全 研究人员目前参与了联邦政府资助的项目 在研究中涉及MRI、CT、PET或SPECT图像的量化 神经精神障碍、中风或中枢神经系统恶性肿瘤。除了提供 快速获得所需的计算能力，该设备将有助于 结合来自不同成像模式的数据。这反过来又会产生 任何单一模式都无法获得重要的科学数据。 此外，该设备将支持方法学的标准化 并通过以下方式鼓励进一步合作 不同研究间影像数据的交换和对照的汇集。

This proposal requests funds to purchase a Silicon Graphics, Inc. 4D240GTX Graphics Supercomputing Workstation with Voxel View software supplied by Vital Images, Inc. This image processing system will enable a multi- disciplinary group of federally-funded researchers with strong collaborative ties to access expensive state of the art computer graphics technology for 3 dimensional volume rendering of brain images. All researchers are currently involved in federally funded projects which involve quantification of MRI, CT, PET or SPECT images in research into neuro-psychiatric disorders, stroke, or CNS malignancies. Besides providing rapid access to needed computational power, this equipment will aid in combining data from different imaging modalities. This, in turn, will yield important scientific data unavailable from any single modality. Additionally, the equipment will support standardization of metholodologies across investigators and encourage further collaboration through interchange of imaging data and pooling of controls across studies.
