This project will contribute towards the development of a portable and low-cost system which can detect the occurrence, and monitor the evolution of stroke and its treatment using microwave technology. The impact of stroke incidents is immense: five million people die and another five million are permanently disabled every year due to stroke incidents, and stroke is placed third among reasons for acute death and first among reasons for neurological dysfunction in the western world. Moreover, the incidence of stroke in patients below 65 years of age is increasing and presently constitutes 20% of all strokes. Its treatment relies to a great extent on the information provided by diagnostic methodologies, which are necessary to guide medical experts in choosing a treatment strategy and to assess its efficiency. The proposed approach relies on microwave imaging (MWI), which uses harmless, low-power, non-ionizing radio frequency microwaves to obtain clinically meaningful images in a way that addresses the patient’s needs for speed, safety and comfort. The system can be used inside an ambulance to determine the type of stroke much earlier than CT scanners inside a hospital. This is particularly important for ischemic stroke patients (which account for over 80% of total cases), for which early detection is crucial for thrombolytic treatment. Moreover, by serving as a point of care diagnostic tool for patients at their homes, the proposed approach can lead to more precise, personalised management of stroke in the post-acute stage, thereby improving the potential recovery of the patient.

该项目将有助于开发一种便携式低成本系统，该系统可以检测中风的发生，监测中风的发展及其使用微波技术的治疗。中风事件的影响是巨大的：每年有500万人因中风事件死亡，另有500万人永久残疾，在西方世界，中风在急性死亡的原因中排名第三，在神经功能障碍的原因中排名第一。此外，65岁以下患者的中风发病率正在增加，目前占所有中风的20%。其治疗在很大程度上依赖于诊断方法提供的信息，这些信息对于指导医学专家选择治疗策略和评估其效率是必要的。所提出的方法依赖于微波成像（MWI），它使用无害、低功率、非电离的射频微波来获得临床有意义的图像，以满足患者对速度、安全性和舒适性的需求。该系统可以在救护车上使用，比医院里的CT扫描仪更早地确定中风的类型。这对缺血性脑卒中患者尤其重要（占总病例的80%以上），早期发现对溶栓治疗至关重要。此外，通过作为患者家中的护理点诊断工具，该方法可以在急性期后对中风进行更精确、个性化的管理，从而提高患者的潜在康复能力。
