• ### The application of computed tomography techniques to imaging with transmitted and reflected ultrasound

Publication Year: 1992, Page(s):4/1 - 4/4
| | PDF (200 KB)

An experimental system has been constructed, based upon conventional linear arrays, to obtain both reflection and transmission data. The transmission data has been used to reconstruct images of the speed of sound distribution within various targets. It has been shown that quantitative speed of sound images, showing good resolution, can be obtained with the reconstruction methods when (a) the atten... View full abstract»

• ### The automated detection of clusters of microcalcifications

Publication Year: 1992, Page(s):3/1 - 3/5
Cited by:  Papers (1)
| | PDF (200 KB)

The algorithm described demonstrates the feasibility of automated detection of microcalcification clusters using edge detection, graph searching, linear discriminant analysis and cluster detection techniques. It represents a significant improvement over other methods with 100% true-positives, 0% false positives using the re-substitution method and 98% true-positives, 0% false positives using the l...

• ### Automated image interpretation in mammography, cytogenetics and retinopathy

Publication Year: 1992, Page(s):2/1 - 2/3
| | PDF (188 KB)

The author describes work which is directed at three areas of medical investigation in which screening of asymptomatic but high-risk cases is carried out. The three applications are rather different medically and work is at different stages of maturity. They exhibit, however, a common approach to screening applications-that of an interactive aid to a trained human assessor. In the author's experie... View full abstract»

• ### An investigation into digital mammography using photo stimulable phosphor computed radiography

Publication Year: 1992, Page(s):5/1 - 5/6
| | PDF (300 KB)

A new X-ray image acquisition technology has been introduced based on photo stimulable luminescence (PSL) called computed radiography (CR). A Philips CR system has been installed in the Diagnostic Radiology department at Leeds General Infirmary. As mammography is one of the most demanding radiological examinations in terms of image quality it was chosen as the focus of an investigation into digita... View full abstract»

• ### Digital mammography review station: user interface, image processing and display considerations

Publication Year: 1992, Page(s):6/1 - 6/4
| | PDF (204 KB)

The aim of this project was to establish the specification for an effective digital mammography review station and investigate the suitability of some of the recent developments in both hardware and software for use in a clinical environment. As the review station is still under development digital mammography images from the CR system are transferred to the laboratory on a weekly basis via a fibr... View full abstract»

• ### Towards the automated prescreening of cervical smears

Publication Year: 1992, Page(s):7/1 - 7/4

| | PDF (176 KB)

The authors present a summary of the results of 4 preliminary investigations into techniques for the automated prescreening of cervical smears based on a database of expertly classified cervical cell images: (1) A comparison of spatial domain features used to classify normal/abnormal cervical cell images; (2) Automatic segmentation of the nucleus in cervical cells; (3) Automatic classification of ...

• ### The Hough transform for locating cell nuclei

Publication Year: 1992, Page(s):8/1 - 8/4
Cited by:  Papers (1)
| | PDF (156 KB)

The motivation in selecting the Hough transform as a means for locating nuclei was its ability to reveal any round' objects in an image. A fast method for detecting ellipses, and hence circles, has been described. This method was applied to a number of typical cervical smear images. The inherent robustness of the Hough transform when dealing with obscured or deformed shapes resulted in few nuclei... View full abstract»

• ### Towards the automated prescreening of breast X-rays

Publication Year: 1992, Page(s):1/1 - 1/5

| | PDF (232 KB)

The Computer Vision Research Group at Dundee is investigating pattern recognition and image processing techniques applied to the automatic interpretation of medical images. One area of interest is in computer interpretation of radiographs for the detection of breast cancer. The authors briefly review some of the projects that have been carried out by the group. These projects have been focused on ... View full abstract»

• ### Automatic classification of cervical cells-using the frequency domain

Publication Year: 1992, Page(s):9/1 - 9/4
| | PDF (144 KB)

The authors present a report of a preliminary study to investigate the effectiveness of spectral analysis techniques to classify cervical cell images as normal or abnormal. In particular an examination was made of the use of texture in the frequency spectra of single cell images to identify the cell class and thereby to discriminate between normal and abnormal. The frequency spectra representation... View full abstract»
