141. Objective measurement of breast cancer oestrogen receptor status through digital image analysis. (Abstract)

were stained with anti-alpha-oestrogen receptor monoclonal antibody (1D5) using a standard immunohistochemical protocol. Images from 10 high-powered fields were captured from each section using a digital camera mounted on a microscope and analyzed using Adobe Photoshop image analysis software. A nuclear mask was obtained by digitally selecting the nuclear area. Staining intensity in the nuclear mask was then analyzed using red-scale absorption characteristics. Manual assessment of oestrogen

142. Is digital image compression acceptable within diabetic retinopathy screening? (Abstract)

the JPEG algorithm within Adobe Photoshop (version 4.0) and then displayed with a Sony Trinitron colour monitor. Four different levels of compression were used, JPEG-1, JPEG-2, JPEG-3, JPEG-4, and an objective analysis was undertaken using 'lesion counts'. The compressed images were assessed separately and blindly and the results compared with their original BMP images.Eight BMP images could not be evaluated (five right eye and three left eye). A total of 290 images were therefore used in the final

143. Effect of software manipulation (Photoshop) of digitised retinal images on the grading of diabetic retinopathy Full Text available with Trip Pro

Effect of software manipulation (Photoshop) of digitised retinal images on the grading of diabetic retinopathy To determine whether software processing of digitised retinal images using a "sharpen" filter improves the ability to grade diabetic retinopathy.150 macula centred retinal images were taken as 35 mm colour transparencies representing a spectrum of diabetic retinopathy, digitised, and graded in random order before and after the application of a sharpen filter (Adobe Photoshop). Digital

144. Technical Report on Semiautomatic Segmentation Using the Adobe Photoshop Full Text available with Trip Pro

Technical Report on Semiautomatic Segmentation Using the Adobe Photoshop The purpose of this research is to enable users to semiautomatically segment the anatomical structures in magnetic resonance images (MRIs), computerized tomographs (CTs), and other medical images on a personal computer. The segmented images are used for making 3D images, which are helpful to medical education and research. To achieve this purpose, the following trials were performed. The entire body of a volunteer (...) was scanned to make 557 MRIs. On Adobe Photoshop, contours of 19 anatomical structures in the MRIs were semiautomatically drawn using MAGNETIC LASSO TOOL and manually corrected using either LASSO TOOL or DIRECT SELECTION TOOL to make 557 segmented images. In a similar manner, 13 anatomical structures in 8,590 anatomical images were segmented. Proper segmentation was verified by making 3D images from the segmented images. Semiautomatic segmentation using Adobe Photoshop is expected to be widely used

145. Evaluation of chronic periapical lesions by digital subtraction radiography by using Adobe Photoshop CS: a technical report. (Abstract)

Evaluation of chronic periapical lesions by digital subtraction radiography by using Adobe Photoshop CS: a technical report. The purpose of this study was to describe a new technique by using Adobe Photoshop CS (San Jose, CA) image-analysis software to evaluate the radiographic changes of chronic periapical lesions after root canal treatment by digital subtraction radiography. Thirteen upper anterior human teeth with pulp necrosis and radiographic image of chronic periapical lesion were (...) endodontically treated and radiographed 0, 2, 4, and 6 months after root canal treatment by using a film holder. The radiographic films were automatically developed and digitized. The radiographic images taken 0, 2, 4, and 6 months after root canal therapy were submitted to digital subtraction in pairs (0 and 2 months, 2 and 4 months, and 4 and 6 months) choosing "image," "calculation," "subtract," and "new document" tools from Adobe Photoshop CS image-analysis software toolbar. The resulting images showed

147. How to Optimize Radiological Images Captured from Digital Cameras, Using the Adobe Photoshop 6.0 Program Full Text available with Trip Pro

How to Optimize Radiological Images Captured from Digital Cameras, Using the Adobe Photoshop 6.0 Program Over the past decade, the technology that permits images to be digitized and the reduction in the cost of digital equipment allows quick digital transfer of any conventional radiological film. Images then can be transferred to a personal computer, and several software programs are available that can manipulate their digital appearance. In this article, the fundamentals of digital imaging (...) are discussed, as well as the wide variety of optional adjustments that the Adobe Photoshop 6.0 (Adobe Systems, San Jose, CA) program can offer to present radiological images with satisfactory digital imaging quality.
