INTRODUCTION During the last decade, whole slide images (WSI) have been used in many areas of pathology such as teaching, research, digital archiving, teleconsultation and quality assurance testing. However, WSI have as yet not much been used for upfront diagnostics because of the lack of validation studies. OBJECTIVES The aim of this study was to test the feasibility of WSI for primary diagn...
At this time, the quality of a Whole Slide Image (WSI) is verified a posteriori by a technician or a pathologist. A WSI of insufficient quality needs to be scanned again. High-speed automatic quality assessment tools for WSI will therefore greatly improve laboratory workflow. We describe here a fast method to automatically assess WSI quality, with different tests such as blurriness, contrast, b...
This note analytically derives the impact that wrong and missing sire information (WSI and MSI, respectively) has on the reliability of predicting merit and gain compared with perfect information. In particular, for small WSI and MSI, WSI was shown to have twice the impact of MSI for both reliability and gain, and the impact of both WSI and MSI increased as the reliability of predicting merit w...
Most prior studies of primary diagnosis in surgical pathology using whole slide imaging (WSI) versus microscopy have focused on specific organ systems or included relatively few cases. The objective of this study was to demonstrate that WSI is noninferior to microscopy for primary diagnosis in surgical pathology. A blinded randomized noninferiority study was conducted across the entire range of...
BACKGROUND Whole slide Imaging (WSI) has been touted by many as the future of pathology, with estimates of full adoption occurring sometime in the next 5 to 15 years. While WSI devices have become increasingly capable since their inception, there has been little consideration of how WSI will be implemented and subsequently affect the workflow of high volume histology laboratories. METHODS His...
While the use of WSI technology to increase the integration density of RAM devices may not be cost effective (cf. Anamartic’s failed WSI RAMs [23]), low defect tolerance overheads, high testability, and low power consumption make memories ideal building blocks for WSI processor architectures. Indeed, this is reflected in the number of memory-based WSI devices manufactured to date [15,19,22,23,24].
Word Sense Induction (WSI) is an unsupervised learning approach to discovering the different senses of a word from its contextual uses. A core challenge to WSI approaches is distinguishing between related and possibly similar senses of a word. Current WSI evaluation techniques have yet to analyze the specific impact of similarity on accuracy. Therefore, we present a new WSI evaluation that quan...
Background Since microscopic slides can now be automatically digitized and integrated in the clinical workflow, quality assessment of these Whole Slide Images (WSI) has become a crucial issue. At this time, the quality of a WSI is verified a posteriori by a technician or by a pathologist. There is however a significant amount of WSI that are too insufficient in quality (blurred, bad colors, poo...
BACKGROUND Whole slide imaging (WSI) makes it possible to capture images of an entire histological slide. WSI has established roles in surgical pathology, including support of off-site frozen section interpretation, primary diagnosis, educational activities, and laboratory quality assurance (QA) activities. Analyses of the cost of WSI have traditionally been based solely on direct costs and dia...
AIMS Experience in the use of whole slide imaging (WSI) for primary diagnosis in pathology is very limited. We aimed to determine the accuracy of interpretation of WSI compared with conventional light microscopy (CLM) in the diagnosis of routine gynaecological biopsies. METHODS All gynaecological specimens (n=452) received over a 2-month period at the Department of Pathology of the Hospital C...
