Acquisition of digital chest images for pneumoconiosis classification: Methods, procedures, and hardware

Development of Standard Digital Images for Pneumoconiosis

We developed the standard digital images (SDIs) to be used in the classification and recognition of pneumoconiosis. From July 3, 2006 through August 31, 2007, 531 retired male workers exposed to inorganic dust were examined by digital (DR) and analog radiography (AR) on the same day, after being approved by our institutional review board and obtaining informed consent from all participants. All...

Comparison of digital direct readout radiography with conventional film-screen radiography for the recognition of pneumoconiosis in dust-exposed Chinese workers.

OBJECTIVES Pneumoconiosis in China remains a disease with substantial public health significance. Diagnostic standards for the pneumoconioses are based on traditional film-screen radiography (FSR). However, FSR is increasingly being replaced with digital radiographic imaging, which has become the predominant technology available in Chinese clinical practice. To evaluate the applicability of dig...

Computer Aided Detection for Pneumoconiosis Screening on Digital Chest Radiographs

This paper presents a computer aided detection scheme on digital chest radiographs for pneumoconiosis screening. The scheme involves several medical image processing and analysis technologies, i.e. lung segmentation algorithm using the active shape model, image enhancement and features extraction from lung regions, feature down-selection by correlation analysis and clustering method, classifica...

Lossless Microarray Image Compression by Hardware Array Compactor

Microarray technology is a new and powerful tool for concurrent monitoring of large number of genes expressions. Each microarray experiment produces hundreds of images. Each digital image requires a large storage space. Hence, real-time processing of these images and transmission of them necessitates efficient and custom-made lossless compression schemes. In this paper, we offer a new archi...
