| 9. A method of image processing, comprising:
using a processor to perform the steps of:
a first acquisition step of acquiring, from a data server, a first portion of data as a data stream obtained from image data
that has been sequentially converted and encoded, the image data representing an X-ray image;
a decoding step of decoding the data acquired in the first acquisition step and obtaining a two-dimensional image;
an analysis step of analyzing the two-dimensional image obtained in the decoding step by providing a medical diagnostic support
and determining a region of interest within the two-dimensional image; and
a second acquisition step of acquiring, from the data server, a second portion of data as a data stream obtained from the
image data based on the region of interest determined in the analysis step,
wherein a degree of resolution of the image data acquired by said first acquisition step is lower than that of an original
image and its spatial resolution and density resolution are determined based on a type of diagnosis,
wherein a degree of resolution of the image data acquired by said second acquisition step is higher than that of the image
data acquired by said first acquisition step, wherein said second acquisition step specifies a tile region or a code block
for the region of interest, and instructs the data server to expedite transfer of the data stream of the specified tile region
or code block, and
wherein the region of interest is a region deemed to be tested positive based on results of the medical diagnostic support
provided by said analysis step.
