HIGH RESOLUTION AND LOW COST STATIC TELEPATHOLOGY
In addition to the cost of the microscope and the computer, the total cost for the additional equipment and software used here was less than $800 US. This is in contrast to images obtained with high definition digital cameras costing between $5,000 and $10,000 US.
For comparative purposes, we used a color TV camera with 450 lines of resolution adapted to an image grabbing card and with a total cost of approximately $1,600 US. The images obtained with this TV camera were compared with those obtained with our system of combined slide photography and scanning. The comparative images of the same microscopic field from Case 6 are presented in Figure B and show the significant difference in resolution between both systems. The only important advantage of using the TV camera over our proposed system was the saving of approximately two hours, corresponding to the time used to develop the film.
The HP scanner used here was able to scan and digitize directly, without the use of the microscope, high resolution images from histological glass slides. We obtained images of the whole specimen as well as closeup images similar to those obtained with 2x objective lenses (see examples).
Table 1 shows the results of the diagnoses for all six cases presented here submitted by a total of 30 pathologist participants. The statistical analysis of these results are not included in this presentation.
