“…Results from other researches and our current project of real-time rendering on programmable graphics units indicate that volumetric displays that allow multiple reformatted viewing angles by rotating images can help reduce ambiguity caused by some poorly differentiated spacial relationships including tissue superimposition [26,27,28]. The advantage of multiple reformations can be more appreciated by volumetric displays than single slice based display.…”

“…To help radiologists more efficiently handle the volumetric data such as data from CT and MR, many programs were implemented to render and display the data to be visually comprehensible. The results and feedbacks seemed very positive regarding to the performance [13,16,26]. The actual clinical utility and impact, however, are not well documented and demonstrated.…”

ABSTRACTThe main purpose of this project is to investigate the feasibility and efficacy of using a stereo display workstation for lung cancer screening on CT images. The tasks included in this project are development and evaluation of stereo image projection and display for chest CT images, observer performance evaluation for the stereo display, and stereo feature analysis and comparison to the conventionally used display methods for lung cancer detection. In the previous report period, we have built a stereo display workstation for chest CT images and conducted a pilot observer performance study. In this annual report period, we have continued the study based on the projected tasks as listed below. 1. Analyzing the results from the pilot study: we applied Free-response Receiver Operating Characteristic (FROC) statistic method to analyze the data from the pilot study for lung nodule detection and classification. Results indicate that the stereo display achieved the best performance followed by the slice-by-slice display, and the conventional MIP display gave the worst performance, although there is no statistically significant difference between the three display modes. Subjective assessment indicates that the stereo display was well accepted by the radiologists. Efficiency measurement indicates that the radiologists spent the least interpretation time with the stereo display when compared to the other two display modes. Further analysis of the radiologists' interpretation patterns indicates that novelty and training effect substantially influenced the radiologists' interpretation behavior and performance. The conclusion from the preliminary results is that we have observed a potential role of stereo display for improving radiologists' performance in medical detection and diagnosis, and also observed some factors likely affecting the performance with new display, such as novelty, training effect and confidence with the new technology, including the stereo display.

“…1B–E); underestimation of the craniocaudad extent of disease; difficulty displaying complex 3-dimensional relationships of the airway, and inadequate representation of airways oriented obliquely to the axial plane [1, 2, 12, 13, 14, 15, 16, 17]. Such limitations have important implications for the assessment of certain airway disorders such as airway stenoses and complex, congenital airway abnormalities.…”

“…Multiplanar and 3-D reconstruction images can help to overcome the limitations of axial images by providing a more anatomically meaningful display of complex structures such as the airways [1, 2, 12, 13, 14, 15, 16, 17, 18]. For example, such images have been shown to enhance the detection of airway stenoses (fig.…”

Additional benefits of multiplanar and 3-D images of the central airways include: improved diagnostic confidence of interpretation; enhanced pre-procedural planning for bronchoscopy and surgery, and improved communication between radiologists, clinicians and patients [1, 2, 12]. Moreover, because multiplanar and 3-D images effectively reduce large CT datasets to a considerably smaller number of images, these methods also facilitate an efficient review of pertinent findings between radiologists and referring clinicians.…”

Recent technological advances in CT imaging have revolutionized non-invasive imaging of the central airways. It is now possible to image the entire central airways in a few seconds and to create elegant three-dimensional reconstructions of the airways in a few minutes. The fast speed of CT scanning now allows for a dynamic assessment of the central airways, expanding the ability to non-invasively detect functional abnormalities such as tracheobronchomalacia. The purpose of this article is to familiarize clinicians with recent advances in airway imaging. A special emphasis is placed upon advanced CT reconstruction methods and their potential contributions to the evaluation of a variety of airway disorders.
