“…The multimodal, multiscale imaging system with AR capability can potentially be applied to multiple surgical subspecialities, such as general surgery, surgical oncology, neurosurgery, plastic surgery, and orthopedic surgery. Multimodal image guidance during surgery can provide surgeons with complementary information of structural imaging and functional imaging [ 70 , 71 , 72 , 73 ]. Strengths of each modality can be combined, and shortcomings of individual can be avoided.…”

A novel multimodal, multiscale imaging system with augmented reality capability were developed and characterized. The system offers 3D color reflectance imaging, 3D fluorescence imaging, and augmented reality in real time. Multiscale fluorescence imaging was enabled by developing and integrating an in vivo fiber-optic microscope. Real-time ultrasound-fluorescence multimodal imaging used optically tracked fiducial markers for registration. Tomographical data are also incorporated using optically tracked fiducial markers for registration. Furthermore, we characterized system performance and registration accuracy in a benchtop setting. The multiscale fluorescence imaging facilitated assessing the functional status of tissues, extending the minimal resolution of fluorescence imaging to ~17.5 µm. The system achieved a mean of Target Registration error of less than 2 mm for registering fluorescence images to ultrasound images and MRI-based 3D model, which is within clinically acceptable range. The low latency and high frame rate of the prototype system has shown the promise of applying the reported techniques in clinically relevant settings in the future.

Minimally invasive medicine has become mainstream because of its crucial clinical significance in providing a low risk of postoperative complications, limited blood loss, short postoperative recovery time, and small sizes of associated physiological tissue wounds. Endoscopic navigation systems comprise a research hot spot in medical science and technology and are an essential means to achieve precision medicine and improve surgical operation safety. As a core component in endoscopic navigation during minimally invasive surgery, endoscopes play a critical role in disease diagnosis and treatment. The development of endoscopic vision technologies has resulted in a renewed drive to further develop endoscopic navigation systems. Multiple endoscopic optical imaging modalities provide data sources for endoscopic vision technology, including white-light endoscopy, contrast-enhanced imaging and technologies involving magnified observation. Endoscopic vision is a specific application of computer vision involving the use of endoscopes that include instrument tracking, endoscopic view expansion, and suspicious lesion tracking in the application of endoscopic navigation. These techniques help surgeons or surgical robots locate instruments and lesions and expand the field of view of the endoscope. Although these technologies have been applied to various clinical and pre-clinical diagnoses and treatments, the use and combination of these advanced technologies in endoscopic navigation system for specific clinical requirements remains challenging. This review performs a broad survey of advanced endoscopic vision technologies and their application in endoscopic navigation systems. Finally, we discuss the challenges and future directions in implementing and developing endoscopic navigation systems.

“…While other methods such patient-specific instruments, custom 3D printed implants and computer aided preoperative planning have also been reported in the literature, the barrier to access with regards to initial investment is much greater (17,18). In this pilot study, the authors present our initial experiences with 3D printed patient-specific models produced in-house with open source software for pre-surgical planning.…”

3D Printed Patient-Specific Complex Hip Arthroplasty Models Streamline the Preoperative Surgical Workflow: A Pilot Study

et al. 2021

Introduction: Surgical planning for complex total hip arthroplasty (THA) often presents a challenge. Definitive plans can be difficult to decide upon, requiring unnecessary equipment to be ordered and a long theatre list booked. We present a pilot study utilising patient-specific 3D printed models as a method of streamlining the pre-operative planning process.Methods: Complex patients presenting for THA were referred to the research team. Patient-specific 3D models were created from routine Computed Tomography (CT) imaging. Simulated surgery was performed to guide prosthesis selection, sizing and the surgical plan.Results: Seven patients were referred for this pilot study, presenting with complex conditions with atypical anatomy. Surgical plans provided by the 3D models were more detailed and accurate when compared to 2D CT and X ray imaging. Streamlined equipment selection was of great benefit, with augments avoided post simulation in three cases. The ability to tackle complex surgical problems outside of the operating theatre also flagged potential complications, while also providing teaching opportunities in a low risk environment.Conclusion: This study demonstrated that 3D printed models can improve the surgical plan and streamline operative logistics. Further studies investigating the optimal 3D printing material and workflow, along with cost-benefit analyses are required before this process is ready for routine use.
