A wireless image acquisition system for artificial knee implant surgeries

A wireless image acquisition system has been proposed and implemented to improve the surgery quality of total knee arthroplasty (TKA) by providing direct images inside the artificial knee implants. The system consists of an image sensing device, a wireless data logger and the image display workstation. The sensing device has the identical dimension and size as the real spacer part in the implants. It is inserted into the knee implant to take the inside images. It is connected with the external data logger through a 432MHz wireless link. Circuit design details for the sensing device as well as the entire system will be discussed. Image processing methods to enhance the image quality under the specific extremely-low luminance environment will be presented.
