Resumen:
Un hospital de Singapur ha desarrollado un sistema de realidad aumentada que permite a los usuarios planificar mejor el tratamiento láser antes de la cirugía y que ofrece los medios para avisar a los usuarios durante la cirugía en el momento en el que el láser alcanza áreas que deben ser protegidas. La tecnología incluye la fase de planificación preoperatoria y la fase de cirugía con láser. En la fase de planificación preoperatoria, se utilizan métodos avanzados asistidos por ordenador y conocimiento clínico para producir una imagen de referencia que se obtiene de la fusión de imágenes de múltiples modalidades. Durante la cirugía con láser, se emplean técnicas avanzadas de procesamiento de imágenes para hacer un seguimiento de la posición del láser en las imágenes de referencia. El hospital busca pymes o centros médicos con el fin de establecer acuerdos de licencia o cooperación en materia de investigación.

Tittle:
Augmented reality technology eye surgery platform through multi-modality image and robot guided system
Summary:
A Singapore hospital has developed an augmented reality system which will allow users to better plan for the laser treatment during pre-surgery and provides means to warn the users during actual surgery when the laser is targeting areas which should be protected.

The hospital is interested in establishing license agreements or research cooperation agreements with SMEs of all sizes or healthcare research institutions.
Description:
Retinal laser therapy is widely used in many retinal diseases especially in diabetic retinopathy. Laser treatment targets retinal pigment epithelial cells that result in coagulation of proteins thereby resulting in ablation of the retina. However, the laser treatment is generally operator-dependent and inadvertent foveal burns can occur which can result in permanent severe central scotoma.

This augmented reality (ARTEMIS) system will allow users to better plan for the laser treatment during pre-surgery and provides means to warn the users during actual surgery when the laser is targeting areas which should be protected.

This technology comprises the pre-surgical planning phase and the live laser surgery phase. In the pre-surgical planning phase, state-of-the-art computer aided methods is utilized together with clinical knowledge to produce a reference image obtained from a fusion of images from multi-modalities. During the laser surgery phase, state- of-the-art image processing techniques will be used to track the position of the laser on the reference images. Working with clinicians, suitable warning and laser controlling mechanisms will be utilized to assist the operators to achieve better surgical outcomes.

The pre-surgical planning phase comprises of multi-modal image registration tool, which is based on LoSPA (Low-dimensional Step Pattern Analysis) algorithms. Its success rate is 79.17% compared to other state-of-the-arts algorithms. The tracking module tracks the movement of the laser and sends out alerts when it is aiming at sensitive regions.

The hospital is interested in establishing license agreements and research cooperation agreements with partner from the healthcare industry, such as an SME of any size to commercialise the technology, or with a research institute for further R-Y-D.
Advantages and Innovations:
This technology can be employed in pre-surgical planning and laser treatment of eye diseases. The multi-modal image registration module can be marketed as a separate product or integrated into existing eye photography hardware. The tracking module may be integrated into eye laser surgery devices. This allow the device manufacturer to disable the laser when it is going to fire at zones that will potentially cause serious damage to the patients´ retina.

The most incentivized stakeholder would be the clinician-surgeon performing the laser procedure. The proposed system allows better planning for the surgery for improved efficacy and best visual outcomes for the patient. The safety mechanisms also mean that surgeons will feel more comfortable with the procedures regardless of their level of training.

A patient undergoing laser procedure will also feel safer with this proposed laser system. The patient will be assured that the laser ablation process is pre-planned for maximum safety and efficacy, but yet preserves healthy retinal tissue and maximise visual function.
