Abstract

Positron Emission Tomography (PET) is an emerging medical imaging methodology for diagnosing cancer. The optimization and security solutions surrounding this technology are essential issues in biomedical engineering. Low-resolution and unauthorized modification of medical images will affect clinical analysis and medical diagnostics. To improve image quality and security while minimizing its impact on medical hardware, this paper analyzes a highly integrated data acquisition approach based on Time-over-Threshold (ToT) and proposes a lightweight security solution based on Physically Unclonable Function (PUF) for PET scan medical hardware. Compared to existing applications, the time-based sampling method can provide very good image quality, and the proposed watermarking and encryption method based on PUF enables enhanced privacy protection with fewer hardware costs for PET medical imaging technology.
