A method is presented for the calculation of perfusion parameters in dynamic contrast enhanced MRI. This method requires identification of enhancement curves for both tumor tissue and plasma. Inter-operator variability in the derived rate constant between plasma and extra-cellular extra-vascular space is assessed in both canine and human subjects using semi-automated tumor margin identification...

The current practice of manual inspection of solder joints in electronic manufacturing is very costly and not very effective. It has been anticipated that automated inspection systems would be developed for this application that would yield great productivity gains, coupled with substantial cost savings over manual inspection. However, the few automated systems for this task that have been plac...

BACKGROUND As imaging centers produce higher resolution research scans, the number of man-hours required to process regional data has become a major concern. Comparison of automated vs. manual methodology has not been reported for functional imaging. We explored validation of using automation to delineate regions of interest on positron emission tomography (PET) scans. The purpose of this study...

The enzymatic method for the determination of ammonia with glutamate dehydrogenase has been adapted to the AutoAnalyzer. The automated method was applicable for NH(3) measurement in sheep rumen samples, swine gut fluid samples, and bovine plasma. Results were compared with those of the Conway diffusion method and the manual enzymatic method. The automated method allows 30 samples per h to be an...

The growing interest of the requirements engineering (RE) community to elicit user requirements from large amounts of available online user feedback about software-intensive products resulted in identification of such data as a sensible source of user requirements. Some researchers proposed automation approaches for extracting the requirements from user reviews. Although there is a common assum...

Automated Essay Scoring (AES) has been quite popular and is being widely used. However, lack of appropriate methodology for rating nonnative English speakers’ essays has meant a lopsided advancement in this field. In this paper, we report initial results of our experiments with nonnative AES that learns from manual evaluation of nonnative essays. For this purpose, we conducted an exercise in wh...

The complete segmentation of the common carotid artery (CCA) bifurcation in ultrasound images is important for the evaluation of atherosclerosis disease and the quantification of the risk of stroke. This requires the extraction of the intima-media complex (IMC), the delineation of the lumen the atherosclerotic carotid plaque and measurement of the artery stenosis. The current research proposes ...

The accuracy of a semi-automated ambulatory blood pressure monitoring device (the Instrumedix 'Personal Blood Pressure Transmitter') was assessed in 36 patients undergoing diagnostic cardiac catheterisation. Blood pressure readings measured by the device and by a standard manual sphygmomanometer were compared with simultaneous intra-aortic pressure measured directly via the catheter. No measure...

OBJECTIVES To assess whether automated screening in the cytologic examination of Papanicolaou smear slides results in smaller margins of error than manual screening. METHODS We compared cytotechnologists' performance and reproducibility of manual and automated screening of 10,165 consecutive cervical cytology slides examined at Barretos Cancer Hospital using the FocalPoint system. RESULTS I...

The ability to automatically segment an image into distinct regions is a critical aspect in many visual processing applications. Because inaccuracies often exist in automatic segmentation, manual segmentation is necessary in some application domains to correct mistakes, such as required in the reconstruction of neuronal processes from microscopic images. The goal of the automated segmentation t...
