X光图像调节:
change window width-->grey scale-> contrast
change window level--> image brightness-->optical brightness
CR resolution increase as
1.psp crystal size decrease
2. laser beam size decrease
3. monitor matrix size increase
the biggest advantages of electronic eelctronic imaging is dynamic range it offer
也被称为LATITUDE, 是线行动态响应范围.
不足是, IPs are sensitive to electromagnetic radiation such as ultraviolet and gamma radiations, alpha and beta particles. so if stored over 48 hours, PSP storage plate should be erased prior to use. |
