Surgeries that require the removal of lesions, such as cancer surgery, place a big burden on both patients and doctors. However, incorporating advanced image recognition technology can make it possible to identify areas of resection efficiently and with high accuracy. This can help ease the time burden on doctors in preoperative simulations. Furthermore, if doctors can reduce the extent of resection, patients could also benefit because the after-effects of surgery can be reduced.
Planning for surgical procedures can be time-consuming and labor-intensive.
The world is facing a chronic shortage of doctors. According to the Institute for Health Metrics and Evaluation（IHME）, there is an estimated shortage of 6.4 million doctors globally, which is likely to increase the time burden on medical care, including in the surgical field*1.
When resection is required due to a disease such as cancer, surgeons usually do preoperative planning in order to determine the appropriate surgical procedure for the situation, to identify the location of the nerves/vessels relative to the affected area, and more. For this, surgeons would individually look through the hundreds of 2D tomographic images acquired by CT and MRI to imagine the location and form of the affected area and the positions of blood vessels. Essentially, they are spending many hours creating a 3D visual in their minds. These tasks are time consuming for surgeons.

Solving problems of doctors and patients with new technology
Christophe Fleury of FUJIFILM Healthcare Europe is introducing our 3D medical image analysis systems to the surgical field in Europe, Middle East and Africa.
――Christophe
I have been involved with Fujifilm’s 3D medical image analysis system since the development stage.
My current role is as an intermediary between surgeons and the IT technicians developing this system. The most rewarding aspect of my job is how we are able to support not only doctors but also patients by developing the features that doctors want.
With the use of new technology, surgical accuracy and efficiency may increase, allowing more patients access to better treatment. By solving the problems of surgeons and patients with our technology, we hope to contribute to people's health.
A high volume of 2D images can become 3D, making it possible to identify resection areas with precision.
――Christophe
In just two to three minutes*2, our 3D medical image analysis system can convert CT and MRI tomograms into highly accurate 3D images, so they can be seen from various angles. It is possible to select areas of the image and make it transparent, assign colors, and more. The surgery can be prepared before entering the operating room, and it can even be used to share the patient's condition with the team.
This 3D medical image analysis system is most often used for lung, kidney, liver, pancreas, and colon cancer surgeries. Not only does it enable a more precise determination of the location of blood vessels compared to just looking at multiple 2D images, but it can also accommodate specific requests of surgeons. For example, if measurements can be made automatically from the 3D reconstructions, it will be easier for surgeons to ensure good safety margins around affected areas before resection.
By using this system in preoperative planning, surgeons can quickly grasp the patient's specific anatomical structures in three dimensions. If doctors are able to see the affected area more precisely, they will be able to reduce the resection area, which can contribute to reducing the postoperative effects for the patient.
One other benefit is its usage in explaining the surgery to the patient. When patients understand the pathology and surgical procedure, it can mostly promote their active participation in treatment and postoperative care.

Listening to surgeons' needs for even better systems
――Christophe
Around 2010, 3D medical image analysis systems were uncommon in the surgical field. That’s when we invited a number of surgeons and gave a presentation about the then-current status of our system.
We had proudly considered our system to be a breakthrough solution, but we were not sure what the surgeons would think of it. However, after I finished my presentation and left the podium, one doctor came over excitedly and said, “I want to use this system as soon as possible in my hospital.”
He became the first surgeon in Europe to adopt our 3D medical image analysis system.
When the surgeon, who performs state-of-the-art surgeries, told us, “this is beneficial to not only me, but to my patients,” we felt even more confident that our solution was in the right direction. Working closely with our technicians, we are determined to keep advancing our system to support all surgeons even more.
I am not a doctor, but I believe that with technology, we can help save the future of more people.
――Christophe
Technology supports us in every aspect of society. It will play an increasingly important role in the field of medicine, in places where we do not usually see it.
I am not a doctor, so I cannot help a patient in front of me like a surgeon. However, if we can improve the efficiency of surgeries and use of time of doctors with our technology and products, I believe we can help to save the future of even more people.
And even as of today, I can say I am working with surgeons on operations, albeit from a distance.
Fujifilm began providing 3D image analysis systems in 2008. We support doctors and patients worldwide by applying to the medical field the image-processing technology that we have continued to pursue over the past 70 years. Automatic extraction from MRI data and enhanced vascular system extraction capabilities are all possible because of the data accumulated over time. We are also taking steps toward further enhancement of AI technology*3 in 3D medical image analysis systems.

The performance and accuracy of the system do not automatically change after market release.
Application of AI Technology in 3D Medical Image Analysis Systems
Deep Learning is a form of AI machine learning that uses an algorithm based on the information-processing mechanisms of the human brain. By having AI learn a large amount of data, we are able to build complex recognition algorithms. Additionally, for Fujifilm’s 3D medical image analysis system, by taking in large amounts of image data of internal organs, the system can comprehend the characteristics automatically. We are developing and operating this technology to detect and measure suspected diseases in target images and areas.
Fujifilm will continue to strive for solutions to support doctors and patients.
For a healthier future.
