摘      要：Compared to surgery,interventional and hybrid-operating-room(OR) approaches diagnose or treat pathology with the most minimally invasive techniques *** minimizing the physical trauma to the patient,peripheral or hybrid approaches can reduce infection rates and recovery time as well as shorten hospital *** invasive approaches therefore are the trend and often the preferred choice,and may even be the only option for the patients associated with high surgery *** interventional imaging modalities include 2-D X-ray fluoroscopy and ***,fluoroscopic images do not display the anatomic structures without a contrast agent,which on the other hand,needs to be minimized for patients *** images suffer from relatively low image quality and tissue contrast *** augment the doctor s view of the patient s anatomy and help doctors navigate the devices to the targeted area with more confidence and a higher accuracy,high-resolution pre-operative volumetric data such as computed tomography and/or magnetic resonance can be fused with intra-operative 2-D images during interventions.A seamless workflow and accurate 2-D/3-D registrationas well as cardiac and/or respiratory motion compensation are the key components for a successful image guidance system using a patient-specific 3-D *** s research has been focused on developing methods and systems of 3-D model guidance for various interventions and hybrid-OR *** s work has led to several Siemens products with high clinical and/or market impact and a good number of scientific publications in leading journals/conferences on medical imaging.
