Abstract

A plurality of CT imaging conditions are created beforehand as presets, each preset is created beforehand as an icon, and each preset is associated with an icon and registered. Each icon is disposed in a CT imaging condition setting screen according to a spatial resolution and density resolution that serve as two-dimensional indexes relating to image quality. The selection of a given icon by a user results in the selection of the CT imaging conditions corresponding to the selected icon. The indexes relate to image quality and are two-dimensional, and this facilitates operation and makes it possible to intuitively select optimal CT imaging conditions with a small number of steps.

First claim

The invention claimed is:

1. A display device having a computer tomographic (CT) software function used in an X-ray CT device, comprising:
control elements configured to register presets for a plurality of CT imaging conditions and arranged on a display screen using a two-dimensional index relating to image quality,
wherein, as one of the control elements is selected, a CT imaging condition corresponding to the selected control element is set,
wherein the control elements are sequentially arranged along a first axis according to a first index relating to image quality, and are sequentially arranged along a second axis according to a second index relating to image quality.

2. The display device according to claim 1 , wherein the index includes a spatial resolution and a density resolution.

3. The display device according to claim 1 , wherein, when the CT imaging condition is selected, a preview image is displayed as an image view serving as a reference of an output image corresponding to the selected condition.

4. The display device according to claim 1 , wherein the control elements are icons arranged side by side across horizontal and vertical directions for each index on the display screen.

5. The display device according to claim 1 , wherein the control elements are displayed independently for each index.

6. The display device according to claim 1 , further comprising imaging condition display means configured to display the set CT imaging condition.

7. The display device according to claim 1 , further comprising imaging condition input confirmation means configured to perform an input operation for confirming the set CT imaging condition,
wherein CT imaging is performed on the basis of the confirmed CT imaging condition in response to the input operation to the imaging condition input confirmation means.

8. The display device according to claim 1 , further comprising a control element that enables selection of a material on the display screen,
wherein, when the control element is selected, a CT imaging condition is set for each material corresponding to the selected control element.

9. The display device according to claim 8 , wherein the control element that enables selection of the material includes a dropdown list, a combobox, a radio button, a checkbox, or a tap.

10. The display device according to claim 1 , wherein a preset of the registered CT imaging condition is configured editably.

11. An X-ray CT device comprising:
an X-ray source that generates an X-ray for irradiating X-rays onto a target object;
a stage for placing the target object;
an X-ray detector that detects the X-ray irradiated from the X-ray source to the target object and transmitted through the target object;
a display device having a CT software function including a function of setting a CT imaging condition; and
a reconstruction processing unit that reconstructs a CT image of the target object from the data detected by the X-ray detector,
wherein the display device comprises control elements configured to register presets for a plurality of CT imaging conditions and arranged on a display screen using a two-dimensional index relating to image quality,
wherein, as one of the control elements is selected, a CT imaging condition corresponding to the selected control element is set,
wherein the control elements are sequentially arranged along a first axis according to a first index relating to image quality, and are sequentially arranged along a second axis according to a second index relating to image quality.
