Abstract

A laser imaging apparatus, such as a storage phosphor reader, which converts a latent x-ray image stored in a storage phosphor into an x-ray image signal. Diagnostic routines for the storage phosphor reader are controlled by means of a touch screen monitor which displays a diagnostic screen having a plurality of selectable buttons.

Claims

1. Storage phosphor reader apparatus comprising:

a laser for producing a laser beam;

scanning means for scanning said laser beam in a line scan direction across a storage phosphor which stores a latent x-ray image to produce an emitted light x-ray image;

translating means for translating said storage phosphor in a page scan direction perpendicular to said line scan direction of said laser beam;

storage phosphor loading means for loading and unloading a storage phosphor relative to said translating means;

photodetector means for detecting said emitted light x-ray image and for producing a corresponding x-ray image signal;

erasing means for erasing said storage phosphor after it is scanned;

a video monitor for displaying said x-ray image signal; and

control means for controlling said laser, said scanning means, said translating means, said storage phosphor loading means, said photodetector means and said erasing means;

wherein said control means includes touch screen means on said video monitor for providing a user interface to said control means, and wherein said control means controls said touch screen means to initially display a main menu on said video monitor which includes, (a) a first user actuable button for initiating automatic operation of said laser, said scanning means, said translating means, said loading means, said photodetector means and said erasing means to produce an x-ray image signal from a latent x-ray image stored in a storage phosphor, and (b) a second user actuable button to sequentially display a diagnostic touch screen after said main menu screen, said diagnostic touch screen having user actuable buttons which are selectable to initiate diagnostic routines to selectively, individually control said laser, said scanning means, said translating means, said storage phosphor loading means, said photodetector means and said erasing means.

2. The apparatus of claim 1 wherein said main menu touch screen includes an image display area for displaying an x-ray image.

3. The apparatus of claim 1 wherein said laser can be turned on and off and wherein said diagnostic touch screen includes user actuable buttons for controlling said laser to be turned on and off.

4. The apparatus of claim 1 wherein said scanning means includes an oscillating mirror driven by a galvanometer which can be turned on and off and wherein said diagnostic touch screen includes user actuable buttons for controlling said galvanometer to be turned on and off.

5. The apparatus of claim 1 wherein said translating means includes a stage for supporting a storage phosphor and drive means for driving said stage in said page direction, and wherein said diagnostic touch screen includes user actuable buttons for controlling said drive means to move said stage and to stop said stage.

6. The apparatus of claim 1 wherein said diagnostic touch screen includes user actuable buttons for controlling loading and unloading a storage phosphor relative to said translating means.

7. The apparatus of claim 1 wherein said photodetector means can be enabled and disabled and wherein said diagnostic touch screen includes user actuable buttons for controlling said photodetector means to be enabled or disabled.

8. The apparatus of claim 1 wherein said erasing means can be enabled or disabled and wherein said diagnostic touch screen includes user actuable buttons for controlling said erasing means to be enabled or disabled.
