Although MRI provides high-resolution images, the device is expensive, the detection process is time-consuming, and there are certain physical requirements for patients; computer tomography generates cross-sectional images of the body's internal structure by rotating X-ray equipment and computer processing, CT scanning can provide detailed bone and soft tissue images, but due to the involvement of high-dose radiation, its use has certain health risks; OCT can provide high-resolution images of tissue structure, but its penetration depth is relatively limited.
