摘要： An interactive three-dimensional (3D) pointing device for selecting points within a subject employs a tracking device which determines the position of the operator, a semi-transparent screen positioned by the operator and the subject and provides this information to a model workstation. The model workstation superimposes computer graphic images of internal structures of the subject on a the semi-transparent screen through which the operator is viewing the subject. The superimposed image is derived from image data either previously generated and stored or obtained with an imaging system. The images of the internal structures are registered with the operator's view of the external structures of the operator. The operator interactively views internal and external structures and the relation between them simultaneously, while moving the screen to select 3D target points at an image depth within the subject. Optionally other input devices may be used to identify current `target points` as selected points. The 3D points are then provided to an output device which utilizes them. Another embodiment employs stereoscopic viewing methods to provide 3D representations of the internal images superimposed on external structures to allow the operator to employ parallax to select 3D points.

摘要： Secondary data set information is incorporated into a primary data set (such as a digital image) retaining a desired dynamic range and retaining the original primary set data quality. The secondary data set information is `smuggled` into the least significant bits of the primary data set to result in an enhanced data set. If desired, the primary data word can be shifted toward the most significant bit. The enhanced data set may be viewed as if it were the original primary data set with existing playback devices, however it now includes additional `smuggled` information which may be played back in coordination with the primary data set information. One example is flow-direction information `smuggled` into an angiographic image. The least significant bits of the enhanced data words may be used to select the color map and color code the images. A user-adjustable intensity threshold can also be employed to select between color maps. Information stored in this fashion results in a substantial savings in disk storage requirements. Also, since the information of the primary and secondary data sets are merged into a single word, they will remain together throughout many different types of processing, such as maximum intensity projection in volumetric imaging.
摘要翻译： 次要数据集信息被并入保留所需动态范围并保留原始主要数据质量的主数据集（例如数字图像）中。 辅助数据集信息被“走私”到主数据集的最低有效位以产生增强的数据集。 如果需要，主数据字可以朝向最高有效位移位。 增强数据集可以被看作是具有现有回放设备的原始主数据集，然而现在包括可以与主数据集信息协调地再现的附加“走私”信息。 一个例子是流向信息“走私”成血管造影图像。 增强数据字的最低有效位可以用于选择彩色图并对图像进行颜色编码。 还可以使用用户可调节的强度阈值来在颜色图之间进行选择。 以这种方式存储的信息可大大节省磁盘存储要求。 此外，由于主要和次要数据集的信息被合并成一个单词，它们将保持在许多不同类型的处理中，例如体积成像中的最大强度投影。

摘要： An MRI system acquires NMR tracking data from a tracking coil imbedded in a medical device which is guided by a physician using real time anatomic images produced from image data acquired by the MRI system. A Hadamard magnetic resonance tracking sequence is used to update the tracking coil location which is indicated on the anatomic image. The Hadamard sequence uses four different acquisition, but tracking coil location is updated after each acquisition, using the new acquisition and three previously acquired acquisitions.

摘要： An interactive surgery planning and display system mixes live video of external surfaces of the patient with interactive computer generated models of internal anatomy obtained from medical diagnostic imaging data of the patient. The computer images and the live video are coordinated and displayed to a surgeon in real-time during surgery allowing the surgeon to view internal and external structures and the relation between them simultaneously, and adjust his surgery accordingly. In an alternative embodiment, a normal anatomical model is also displayed as a guide in reconstructive surgery. Another embodiment employs three-dimensional viewing.
