Abstract: 

This project aims at building a novel portable electromagnetic imaging system for the early diagnosis for knee injuries, which are one of the most common injuries not only among athletes but also among ordinary people. The knee injuries include fractures, ligaments tears, dislocation, bursitis, and tendon tears but the ligaments tears are the most significant injuries in the knee. In Australia alone, nearly 17,000 anterior cruciate ligaments (ACL) are reconstructed per year. Moreover, there are between 100,000 and 200,000 ACL injuries per year in the USA. Females are nine times more likely to experience ACL tears than males.

During the knee injuries, the intra-articular volume increases when hemarthrosis occurs. Which causes pain and limitations in the knee motion, further making difficulty for accurate examination in addition to bleeding within the knee joint makes the diagnosis of ACL tear difficult. Therefore, the traditional diagnosis tools such as arthroscopy, x-rays, computed tomography, magnetic resonance imaging, x-rays, and ultrasound suffer from some limitations such as ionization to the patients, lack of sensitivity, and high cost. For Knee injuries diagnosis, MRI is considered as the golden diagnostic tool for the soft and hard tissues inside the knee. At the beginning of ACL tear, most of the ligaments tear are mild or moderate tears and sometimes are only ligaments stress, therefore, the early detection and classification of the ligaments tear are important especially for the athletes before ligaments complete tear. Therefore, the onsite portable diagnosis tools are required because the MRI and CT systems cannot be used outside the hospital environment to be used onsite.

This study presents an electromagnetic imaging system to diagnose knee injuries especially the soft tissues. The electromagnetic imaging systems are portable, low cost, non-invasive, non-ionization. In addition to that, EMI systems have high contrast, deep penetration, and frequency monitoring that is considered as benefits. This tool will be used as an on-time (in the field) diagnosis tool to prevent the complete tear of ligaments.

The processes in this project include novel antenna design and fabrication, dielectric characterization and modelling of soft tissues, modified the accuracy of electromagnetic algorithms, and phantoms fabrication for healthy and unhealthy cases for system test before clinical trials. In the terms of imaging resolution, penetration depth, antenna size, and system compatibility with the patient, the proposed system will be focused on the lower frequency band from 1 GHz to 4 GHz that offers the best tradeoff between the aforementioned parameters. This project will open the door for researchers for using the EMI system for new applications to detect the injury of soft tissues.
