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，可以将主数据字移向最高有效位，增强数据集可以被看到好像它是现有播放设备的原始主要数据集，但是它现在包括可以与主数据集信息配合播放的其他“走私”信息。一个例子是“走私”到血管造影图像中的流向信息，增强数据字的最低有效位可以用于选择彩色图和彩色图像，还可以使用用户可调节的强度阈值来选择以这种方式存储的信息可以大大节省磁盘存储要求，而且由于主数据集和辅助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，例如作为体积成像中的最大强度投影。

摘要： An invasive probe for determining the morphological characteristics of walls of a lumen employs a real-time tracking means and an optical spectral measurement means. As the probe is advanced within the lumen, the real-time tracking means provides three-dimensional coordinates of the probe's position and orientation. Concurrent with probe localization, measurement of the spectral properties of the lumen wall are made by detecting the reflectance and/or absorption of light at the lumen wall. Both the probe position and the spectral measurement are sent to a data acquisition system which in turn provides an graphic or numeric display to the operator. Probe tracking can be performed with radio-frequency, magnetic resonance, ultrasonic techniques or the like. If desired, spectral measurements can be made in the visible, ultra-violet or infra-red spectral bands to provide optimized detection of chemical species of interest.
