Perceive3D

Perceive3D (commonly abbreviated P3D) is a Portuguese medical-technology company based in Coimbra that develops software solutions for computer-aided surgery. Its core innovation is a video-based technology for surgical navigation that combines intelligent video processing for 3D mapping of the anatomy with Augmented Reality (AR) for overlaying meaningful guidance information directly in the surgical images. The company describes this as the first system of its kind to provide higher metric accuracy while solving the problems of ergonomics and economics, and as the first effective solution for navigation in arthroscopy, where it uses the video already acquired by the existing arthroscopic camera. P3D's product family spans navigation and visualization. Its navigation offering, marketed under the InNav name, is presented as the first AR guidance solution for arthroscopy and for knee surgery, including a navigation system for ACL reconstruction that overlays guidance information in video to help place tunnels according to patient-specific anatomy. The software runs on a universal add-on service device, a handheld tablet, a surgical camera, or even a mixed reality headset, avoiding the need for bulky capital equipment, additional incisions, or bulky markers. Its visualization offering, marketed under the InDepth name, enhances visualization in the operating room by geometrically modeling the camera: it corrects radial distortion to remove the "fish-eye" effect, applies color mapping to highlight morphologic and anatomic elements such as vascularization, brightens dark image regions while preserving contrast, and sharpens contrast and definition using proprietary image sharpening. This software also runs in a universal add-on device that can be connected to a surgical tower. The company is led by co-founders João P. Barreto (Co-Founder & CEO), a recognized expert in 3D computer vision and a professor at the University of Coimbra, and Rui Melo (Co-Founder & CTO), who began his career in camera calibration and real-time image processing for endoscopy systems. João Amaro serves as VP Business Development, bringing more than a decade of sales and business development experience in the medical device field. P3D has pursued patent protection for its disruptive surgical navigation technology and has engaged with the investment and clinical communities, including pitching at the Digital Health Venture Forum in Porto in 2019 and exhibiting at the AAOS annual meeting. The company is privately held.

Perceive3D (P3D) is a Portuguese medical-technology company based in Coimbra that develops solutions for computer-aided surgery. It was founded by João P. Barreto and Rui Melo, who came together around a shared interest in applying 3D computer vision to minimally invasive surgery. Barreto, a professor at the University of Coimbra with a PhD in Electrical Engineering, is a recognized expert in 3D computer vision who previously worked at INRIA Rhone-Alpes and the University of Pennsylvania and has received distinctions including a Google Faculty Research Award. Melo began his career as a researcher in camera calibration and real-time image processing for endoscopy systems; his interest in practical solutions with impact in the medical device sector led to the development of P3D's early prototype software, and he embarked on the entrepreneurial path as co-founder while finishing his PhD. The company created and developed a video-based technology for surgical navigation that combines intelligent video processing for 3D mapping of the anatomy with Augmented Reality (AR) for overlaying meaningful guidance information in images. P3D describes it as the first system of its kind to provide higher metric accuracy while solving the problems of ergonomics and economics, and as the first effective solution for navigation in arthroscopy, where it uses the video acquired by the already existing arthroscopic camera. By 2019 the company was actively building both its intellectual-property portfolio and its market presence. In March 2019 P3D exhibited at the AAOS annual meeting. In May 2019 it was one of the companies selected by the TechTour European community to pitch its investment opportunity to dozens of investors at the Digital Health Venture Forum, held on 23–24 May at Porto Business School. In December 2019 the company announced that two more patents had been granted — described as important milestones in protecting its disruptive surgical navigation technology — and that it had tested groundbreaking software in a cadaver lab. P3D's commercial offerings are organized around navigation and visualization. Its navigation product, InNav, is presented as the first AR guidance solution for arthroscopy and for knee surgery, including a navigation system for ACL reconstruction that overlays guidance information in video to place tunnels according to patient-specific anatomy. The software runs in a universal add-on service device, a handheld tablet, a surgical camera, or even a mixed reality headset, avoiding the need for additional capital equipment, extra incisions, or bulky markers, and offering super-fast registration without line-of-sight constraints. Its visualization product, InDepth, enhances visualization in the operating room by geometrically modeling the camera: correcting radial distortion to remove the fish-eye effect, applying color mapping to highlight morphologic and anatomic elements such as vascularization, brightening dark image regions while preserving contrast, and sharpening contrast and definition. It also runs in a universal add-on device that can be connected to a surgical tower. The management team includes co-founder and CEO João P. Barreto, co-founder and CTO Rui Melo, and VP Business Development João Amaro, who has more than ten years of experience in sales and business development in the medical device field and holds an MSc in Biomedical Engineering from the University of Coimbra. The company is privately held and headquartered in Coimbra, Portugal.
