Abstract
A medical image-processing apparatus includes a display unit configured to display a plurality of medical images obtained at different imaging positions, a setting unit configured to set a point of interest on each of the medical images in accordance with an operation of an operator, an alignment unit configured to align the medical images on the display unit, with the points of interest on the medical images made to coincide with each other, and a post-processing unit configured to perform post processing concerning the medical images aligned by the alignment unit.
Description

BRIEF DESCRIPTION OF THE SEVERAL VIEWS OF THE DRAWING

The accompanying drawings, which are incorporated in and constitute a part of the specification, illustrate presently preferred embodiments of the invention, and together with the general description given above and the detailed description of the preferred embodiments given below, serve to explain the principles of the invention.



FIG. 1 is a block diagram illustrating the configuration of a magnetic resonance imaging apparatus (MRI apparatus) according to an embodiment of the invention;



FIG. 2 is a flowchart illustrating a procedure of stitching two parent images together to form a single image, performed by the controller appearing in FIG. 1;



FIG. 3 is a view illustrating a display image example on the display unit appearing in FIG. 1, obtained after points of interest are set;



FIG. 4 is a view illustrating a display image example on the display unit appearing in FIG. 1, obtained after the points of interest shown in FIG. 3 are made to coincide with each other;



FIG. 5 is a view illustrating a display image example on the display unit appearing in FIG. 1, obtained after the display magnifications of the parent image shown in FIG. 4 are changed;



FIG. 6 is a view illustrating a display image example on the display unit appearing in FIG. 1, obtained after the display position is shifted from that shown in FIG. 5;



FIG. 7 is a view illustrating a positional relationship example between combinations of parent images obtained at different slicing positions for three-dimensional or multi-slicing imaging; and



FIG. 8 is a view useful in explaining a state in which the positional relationships between the parent images included in all combinations are changed in accordance with an instruction to change the positional relationship between the parent images included in a certain combination.


Claims
  • 1. A medical image-processing apparatus comprising: a display unit configured to display a plurality of medical images obtained at different imaging positions;a setting unit configured to set a point of interest on each of the medical images in accordance with an operation of an operator;an alignment unit configured to align the medical images on the display unit, with the points of interest on the medical images made to coincide with each other; anda post-processing unit configured to perform post processing concerning the medical images aligned by the alignment unit.
  • 2. The medical image-processing apparatus according to claim 1, wherein when display ranges of the medical images are changed relative to each other after the points of interest are made to coincide with each other, the setting unit updates the points of interest on the medical images relative to each other to compensate for a displacement between the points of interest which occurs in accordance with changes in the display ranges.
  • 3. The medical image-processing apparatus according to claim 1, wherein the post-processing unit changes a display magnification of at least one of the medical images, with the points of interest on the medical images made to coincide with each other.
  • 4. The medical image-processing apparatus according to claim 1, wherein the post-processing unit changes display densities of the medical images relative to each other.
  • 5. The medical image-processing apparatus according to claim 4, wherein the post-processing unit changes the display densities of the medical images relative to each other to make equal image values, on the display unit, of the points of interest on the medical images, an average display contrast of the medical images, or an average display contrast of overlapping areas included in the medical images.
  • 6. The medical image-processing apparatus according to claim 4, wherein the post-processing unit changes the display densities of the medical images in accordance with an operation of the operator.
  • 7. The medical image-processing apparatus according to claim 1, further comprising a generation unit configured to generate a single medical image by stitching the medical images on the display unit.
  • 8. The medical image-processing apparatus according to claim 1, further comprising an addition unit configured to add, to the medical images on the display unit, a mark indicating a boundary of the medical images aligned by the alignment unit.
  • 9. The medical image-processing apparatus according to claim 1, wherein when there is a combination including other medical images and certain plane different from on which an another combination including the medical images exists, the alignment unit aligns the other medical images of the combination with a same positional relationship as a positional relationship of the medical images of said another combination.
  • 10. A magnetic resonance imaging apparatus comprising: an imaging unit configured to image a subject utilizing a magnetic resonance signal emitted from the subject;a display unit configured to display a plurality of medical images imaged by the imaging unit with a position of imaging varied;a setting unit configured to set a point of interest on each of the medical images in accordance with an operation of an operator;an alignment unit configured to align the medical images on the display unit, with the points of interest on the medical images made to coincide with each other; anda post-processing unit configured to perform post processing concerning the medical images aligned by the alignment unit.
  • 11. A medical image-processing method comprising: displaying, on a display unit, a plurality of medical images obtained at different imaging positions;setting a point of interest on each of the medical images in accordance with an operation of an operator;aligning the medical images on the display unit, with the points of interest on the medical images made to coincide with each other; andperforming post processing concerning the medical images aligned.
