Abstract

The display device for tomographic image has a display, a hard disk, a mechanical slide-bar for setting a display speed for series of tomographic images and a controller. This device is used for displaying tomographic images in the manner of paging on the display for the series based on a speed set by the mechanical slide-bar.

Claims

1. A display device for tomographic image, comprising:

a display portion configured to display at least one series of tomographic images;

a storage mechanism configured to store at least one series of tomographic image data;

a display-speed setting mechanism setting configured to set a display speed for said at least one series of tomographic images; and

a controller configured to receive data from the storage mechanism for displaying the at least one series of tomographic images by paging on the display portion based on the display speed set by the display-speed setting mechanism, wherein

the display-speed setting mechanism is a mechanical slide-bar variable adjuster positioned in a separate case from that a case comprising the controller.

2. A display device for tomographic image, comprising:

a display portion configured to display at least two series of tomographic images;

a storage mechanism configured to store at least two series of tomographic image data;

a display-speed setting mechanism configured to set display speeds of each series for the at least two series of tomographic images;

a controller configured to receive data from the storage mechanism for each series and simultaneously displays the at least two series of tomographic images on the display portion based on the speed the display speeds set by the display-speed setting mechanism; and

a synchronization command sending mechanism configured to match the display speeds for the at least two series of tomographic images, wherein

the controller displays tomographic images of the at least two series by paging while synchronizing the display speeds for the at least two series of tomographic images based on a synchronizing command from the synchronization command sending mechanism, and

the at least two series displayed comprise a first series obtained using a contrast medium and a second series obtained without a contrast medium for a same portion of a body and the first and second series are obtained during a same diagnostic time.

3. The display device for tomographic image as claimed in claim 2, wherein the display-speed setting mechanism is a mechanical variable adjusting knob in a separate case from a case comprising the controller.

4. The display device for tomographic image as claimed in claim 3, wherein the mechanical variable adjusting knob is a mechanical slide-bar type of variable adjuster.

5. The display device for tomographic image as claimed in claim 2, wherein the display-speed setting mechanism is a keyboard or a mouse that based on software sets the display speeds.

6. The display device for tomographic image as claimed in claim 2, further comprising a receiving portion configured to receive a CT value range to be displayed on the image display portion, wherein

the display device is adapted to accomplish the method comprising the steps of:

locating a display area in the form of a bar whose ends define a minimum value and a maximum value of a necessary display range of a CT value;

receiving the CT value range to be displayed on the image display portion;

indicating the received CT value range on the display area using visibly distinctive color;

indicating a center of the received CT value range using further visibly distinctive color or shape; and

showing CT values currently displayed on said image display portion.

7. A display device for tomographic image, comprising:

a display portion configured to display at least two series of tomographic images;

a storage mechanism configured to store at least two series of tomographic image data;

a display-speed setting mechanism configured to set display speeds of each series for the at least two series of tomographic images;

a controller configured to receive data from the storage mechanism for each series and simultaneously displays the at least two series of tomographic images on the display portion based on the display speeds set by the display-speed setting mechanism; and

a synchronization command sending mechanism configured to match the display speeds for the at least two series of tomographic images when a number of image in each of the at least two series is different, wherein

the controller displays tomographic images by paging while synchronizing the display speeds for the at least two series of tomographic images based on a synchronization command from the synchronization command sending mechanism.
