Abstract

A method for setting a scanning protocol and an apparatus thereof are provided. The method includes: creating a plain film positioning image; receiving a point or a line or a region of interest on the plain film positioning image input by an operator; generating a region to be matched, based on the point or the line or the region of interest; determining whether there is pre-stored reference image having a matching degree greater than a preset threshold by comparing pre-stored reference images with the region to be matched; obtaining a reference image in the case that the reference image has a matching degree greater than the preset threshold; selecting a scanning protocol corresponding to the reference image based on a preset correspondence between reference images and scanning protocols; and completing a setting of the scanning protocol in the case that there is the scanning protocol corresponding to the reference image.

First claim

The invention claimed is:

1. A method for setting a scanning protocol, comprising:
creating a plain film positioning image;
receiving a point of interest, a line of interest or a region of interest on the plain film positioning image input by an operator;
generating a region to be matched, based on the point of interest, the line of interest or the region of interest;
determining whether there is a pre-stored reference image having a matching degree greater than a preset threshold, by comparing pre-stored reference images with the region to be matched;
obtaining a reference image in the case that a matching degree between the reference image and the region to be matched is greater than the preset threshold;
selecting a scanning protocol corresponding to the reference image based on a preset correspondence between reference images and scanning protocols; and
completing a setting of the scanning protocol in the case that there is the scanning protocol corresponding to the reference image.

2. The method according to claim 1 , further comprising:
obtaining a reference image with a highest matching degree, in the case that the matching degrees between a plurality of reference images and the region to be matched are greater than the preset threshold.

3. The method according to claim 1 , further comprising:
obtaining one reference image selected by the operator from a plurality of reference images, in the case that matching degrees between the plurality of reference images and the region to be matched are greater than the preset threshold.

4. The method according to claim 1 , further comprising:
selecting one scanning protocol, by the operator, from a plurality of scanning protocols and completing a setting of the scanning protocol, in the case that the plurality of scanning protocols correspond to the reference image.

5. The method according to claim 1 , further comprising:
marking, based on the set scanning protocol, a protocol region of interest corresponding to the scanning protocol on the plain film positioning image; and
modifying, based on an adjustment made to the protocol region of interest by the operator, a coordinate parameter of the scanning protocol.

6. An apparatus for setting a scanning protocol, comprising:
a first obtaining module configured to create a plain film positioning image;
a receiving module configured to receive a point of interest, a line of interest or a region of interest on the plain film positioning image input by an operator;
a generating module configured to generate, based on the point of interest, the line of interest or the region of interest, a region to be matched;
a determining module configured to determine whether there is a pre-stored reference image having a matching degree greater than a preset threshold by comparing pre-stored reference images with the region to be matched;
a second obtaining module configured to obtain a reference image if the determining module determines that a matching degree between the reference image and the region to be matched is greater than the preset threshold;
a third obtaining module configured to select a scanning protocol corresponding to the reference image based on a preset correspondence between reference images and scanning protocols; and
a first setting module configured to complete a setting of the scanning protocol in the case that there is the scanning protocol corresponding to the reference image.

7. The apparatus according to claim 6 , further comprising:
a fourth obtaining module configured to obtain a reference image with a highest matching degree in the case that matching degrees between a plurality of reference images and the region to be matched are greater than the preset threshold.

8. The apparatus according to claim 6 , further comprising:
a fourth obtaining module configured to obtain one reference image selected by the operator from a plurality of reference images in the case that matching degrees between the plurality of reference images and the region to be matched are greater than the preset threshold.

9. The apparatus according to claim 6 , further comprising:
a second setting module configured to receive one scanning protocol selected by the operator from a plurality of scanning protocols and complete a setting of the scanning protocol, in the case that the plurality of scanning protocols correspond to the reference image.

10. The apparatus according to claim 6 , further comprising:
a marking module configured to mark, based on the set scanning protocol, a protocol region of interest corresponding to the scanning protocol on the plain film positioning image; and
a modifying module configured to modify, based on an adjustment made to the protocol region of interest by the operator, a coordinate parameter of the scanning protocol.
