Photoshop is a classic and powerful graphics processing software. It is very effective to post-process CT, MRI and X-ray images obtained by digital cameras and scanners. This post will introduce my experience in using photoshop step by step. Welcome to participate in the discussion and provide more skills to deal with pictures.
I use version 6.0. Let me tell you something:
It's simple. Click "Edit/Adjust/Decolor" on the menu bar, and the image will change to gray mode. Click "Image/Adjustment/Brightness/Contrast" on the menu bar to pop up the following dialog box: Pull the slider, adjust the image to the satisfaction, and click "OK" to exit.
The follow is that adjusted image:
CT and MRI films show hospital name, patient name, gender, age and other information. If there is no coverage, direct uploading may cause unnecessary controversy. So, it's best to block them out.
Click "Rectangular Tool" on the toolbar (please note: Rectangular Tool and Rectangular Option Box are two different tools! ), you can see that there is a rectangular tool options bar under the menu bar.
Notice that the mode is set to normal and the opacity is set to 100%. Then click the "color" button on the right and select black. Now you can press the left mouse button and drag the appropriate size on the image to overwrite the data. You can repeat this operation multiple times to overwrite all the data.
After the operation, remember to click "Layers/Merge Visible Layers" on the menu bar, otherwise the image cannot be saved in JPG format.
The following is the overlaid image:
This operation will use the rectangular marquee tool! Click "Rectangular Box Selection Tool" on the toolbar, press the left mouse button to include the image of interest in a rectangular virtual box, and click "Image/Crop" on the menu bar to eliminate the image outside the area of interest.
The following are the therapeutic effects:
The operation of WCHGH moderator is much more skilled than me! Click "Brush Tool" in the toolbar, and a brush option bar will appear under the menu bar:
Adjust the brush thickness (less than 5 is better), set the mode to normal and the opacity to 100%, and then set the brush color. You can draw a line on the image or describe the area of interest.
Click "Text Tool" in the toolbar, and a text option box will appear under the menu bar, where you can select font type, size and text alignment. I won't describe it in detail here.
Click on the picture at will, and you can enter the text.
When you have finished typing, click "Move Tool" in the toolbar, then hold down the text with the left mouse button and drag it to the appropriate position.
After dragging, remember to click "Layers/Merge Visible Layers" on the menu bar. Otherwise, the next labeling operation cannot be performed and the image cannot be saved in JPG format.
Repeat the above operation, you can add comments countless times.
I don't know if you understand this. Is it detailed enough? Add some points.
