Example Embodiment

[0024] Figure 4 It is a schematic diagram of setting the inspection site in the embodiment of the present invention, and setting the window width and window level value for the inspection site. First of all, by operating the interface of the operating system, a viewing configuration option pops up from the Viewing Configuration. Under this configuration option, set the lungs of the inspection site. Figure 4 Enter the English name of the lungs in the window in the middle, and then click the confirm button Apply, then the setting is complete.

[0025] After completing the setting of the lungs at the examination site, set two sets of window width and window level values ​​for the lungs. The first group has a window width value of 1200 and a window level value of -600; the second group has a window width value of 350 and a window level value of 50. The operator regards the most frequently used window width and window level values ​​as the first set of window width and window level ...

Abstract

The invention discloses a method for adjusting window width and window level in CT scan check, which comprises the following steps: first, at least one checkpoint is set in an option and at least one group of window width and window level value is set for every checkpoint; second, at least one shortcut is set up and every checkpoint is set corresponding to every shortcut. By adopting the method of the invention for adjusting the window width and window level, an operator can press the shortcut directly to switch the window width and the window level and does not need to use a mouse to choose menu items or to adjust the window width and the window level by controlling the knob on a control box, thus being convenient for use and improving diagnostic efficiency as well.

Description

technical field [0001] The invention relates to an adjustment method, in particular to a method for adjusting window width and window level in computer tomography (Computed Tomography; CT) scanning inspection. Background technique [0002] A CT image consists of a certain number of small squares with different gray levels from black to white, and each square is the smallest unit of the image, called a pixel (Pixel). CT value is a numerical value to illustrate the level of tissue image density. It is not an absolute value, but a relative value compared with water in other tissues, and the unit is Henry (H). That is to say, the CT value of water is 0H, that of air is -1000H, and that of bone is more than 4000 grades of +3720H. Various tissues of the human body are included in the above grades. In fact, the sensitivity of the human eye cannot distinguish so many gray levels (the human eye can only recognize 16 gray levels), and the display device cannot display so many gray l...
