Abstract

Cancer is the second-leading cause of death worldwide. Even with modern technology, operation on tumors is still considered one of, if not the most effective treatment to cancer illness. However, according to a scientific journal [1], incomplete tumor resection from cancer operations occurs in 25% of breast cancer patients, 35% of colon cancer patients, and 40% of head and neck cancer patients. Because surgical procedures, especially tumor operations, require high degree of accuracy and precision, the use of biomedical cameras for vision aid are fundamental in reducing the risks associated with any visual accidents involved. To develop such a system, I implemented a lens-controller module on a Field Programmable Gate Array (FPGA) that consisted of Python code for its software and Verilog code for its hardware. This module allows the user to communicate and receive image data from a Canon EF CMOS image sensor through the implemented hardware, software, and the communication protocol in the embedded system. I plan to use the FPGA to change the focus and the aperture of the Canon lens, while also having strong reliability in terms of running for several hours without encountering any glitches nor bugs, as this module will be used in tumor operations that may last for hours. Throughout the project, I have learned several methods to implement the hardware of the module as well as its communication protocol, and how the software portion of the module interacts with the firmware.
