Abstract
The Internet of Things (IoT) in the operating room can aid to improve the quality of the computer-aided surgical system. Patient-to-image registration is an important issue for computer-aided surgical systems. Automating the procedure of patient-to-image registration could increase tracking accuracy and lower the time consumed for performing the procedure of registration. Therefore, we propose an automatic registration method to address this issue by constructing a wireless sensor network system for surgery. A plastic fiducial object combing with specific markers is developed to perform registration in that the ultimate purpose is to integrate them into a surgical robotic system for surgical navigation. The specific markers are designed to localize the position of the small EM sensor and can be automatically detected in CT/MRI images by an automatic algorithm. The positions of the EM tracking sensors can be calibrated during the procedure of registration. Some experiments are designed and performed, and the experimental results demonstrate that the proposed registration method is robust and accurate. The proposed registration method is a foundational link of the surgical robots combing with virtual or augmented reality technology that all these technologies will be performed in further surgical navigation.
Highlights
The Internet of Things (IoT) in the operating room is the concept of medical devices in the operating room connected to each other via the Internet to make the medical devices smart
The EM tracking technology combined with 2D or 3D images, which is achieved by computed tomography (CT), magnetic resonance (MR) imaging (MRI), or ultrasound, has been applied in clinics for various procedures by navigating medical instruments [1, 6, 7]
To achieve the aim of convenient and fast registration, we develop an automatic and accurate registration method which integrates the performance of patient-image registration and the calibration of fiducial object and EM sensors
Summary
The Internet of Things (IoT) in the operating room is the concept of medical devices in the operating room connected to each other via the Internet to make the medical devices smart. The performance of the IoT operating room can aid to improve the quality of the surgical navigation system. Image-guided surgical navigation is a computer-aided system that can help the surgeons use a tracking medical instrument for the treatment of specific diseases, which assists surgeons in improving therapy and reducing invasiveness and complications [1, 2]. Anatomical landmarks combining with the fiducial markers are manually selected to perform image-patient registration in image and patient spaces which is a widely used routine procedure in image-guided navigation [9]. Since the positions of anatomical landmarks and fiducial markers are picked by a pointer in patient space or selected manually on a computer screen, their positions are subject to manual measurement errors which results in inaccurate registration [11]
