Confronting cancer

If cancer develops, surgery is available. Alternatives to surgical therapy include radiation therapy and chemotherapy. If cancer cannot be suppressed with these therapies, life-prolonging treatment is possible, and palliative care is also available. Just because you develop cancer does not mean that your life is over. Currently, there are various therapeutic methods that have accumulated over a long time that are advancing at a rapid pace, and perhaps people with chronic ailments would live longer. There are various types of cancer, and most of them seem to allow for a better quality of life (QoL) than other diseases until considerable time passes.

Conversely, cancer is difficult to detect for the same reason, so cancer screening is vital. If you want to live out a full life, you should have cancer screening. Screening does not allow you to escape all diseases, but you can avoid the ones that would strike unexpectedly. You shouldn’t say that you have already lived for a sufficiently long period. We should appreciate honestly that we are still alive and think what we should do in this world.

You can work if there is understanding of people around you

It is inevitable that cells come to a programmed end for living things to maintain their form. Programs are destined to go out of control from time to time. People have a risk of developing cancer irrespective of how much they try to live in a healthy way. Therefore, you don’t need to feel compassion for me.

However, aftereffects sometimes persist. It is not a matter of importance that I lost a half of my stomach, which is a storage organ. The problem is that I lost the valve at the exit of my stomach. When food enters the intestine directly, my blood sugar rises rapidly, then insulin is secreted, and in turn, my blood sugar drops rapidly. My pulse increases, my body temperature decreases, and I feel hot sensations for some reason. I feel sick and lightheaded. Dumping is hard to overcome. But I have become used to it. I recover by eating a banana at the right time. I sometimes become almost unconscious suddenly when I use my brain, but there is no problem as long as I have a banana. There is no problem as long as I have the understanding of people around me. You don’t need to feel sorry for me. I just hope that you can understand the disorder that cannot be seen from the outside. If a part of the body is lost, specific disorders remain. To a greater or lesser extent, this would be the same for other types of cancer.

My energy has not decreased since I developed cancer. In fact, I rather feel like my daily life is condensed. What can I do in this world? How about creating a computer-aided 3D endoscope with my students? In this world, I should invent a beneficial instrument to control the pernicious cancer that has changed my view of life and offered the joy of living at the same time.

If there is a computer-aided 3D endoscope

In contrast to the traditional stereoscopic endoscopes based on the left and right parallel image transmission method that do not create 3D data (for example, by looking into binocular stereo [micro] scopes or wearing eyeglasses), computer-aided 3D endoscopes would provide various advantages inherently derived from the independence of input and output.

[Wide field] The area of stereoscopic view is not limited to the area around the point where incident optical axes to left and right image sensors that are arranged inward cross, but rather it covers the entire area of common view between left and right image sensors that are arranged in parallel.

[No need for special skills] Special skills—which are required for the traditional left and right parallel image transmission method with which images need to be taken in the front as far as possible and observed with slightly cross-set eyes to enhance the stereoscopic effect from binocular parallax—are unnecessary.

[Output versatility] Any type of 3D display equipment can be used for the output.

[Arbitrary viewpoint] Rendering is enabled from an arbitrary viewpoint for output, independently from the viewpoint for input. Many people can observe from their own arbitrary viewpoint at the same time.

[Depth processing potential] By processing 3D data, partial enlargement in depth direction to emphasize the depth and unevenness is allowed flexibly. The unevenness provides an important key to testing and surgery.

[Measurability] The distance between any two points on the surface of the object can be measured immediately from 3D data.

[Data integrity] While 3D data on the surface of the object can be created in real time, it can be integrated with CT and other 3D data inside of the object that are taken beforehand.

[Low introduction risk] This instrument does not have the limitation that requires alternative use of 3D display equipment for observation (for example, by looking into binocular stereo [micro] scopes or wearing eyeglasses), and it can be used as an option to traditional endoscopes.

Seeking cooperative companies or rivals

Money is necessary for us to live, but I don’t want to live just for money. I was able to receive cancer treatment with my own money, so I will try to advance my research with my saved life. I am seeking cooperative companies. If companies cannot cooperate, isn’t it impossible for companies to develop in-house? I will disclose information. Anybody can work to confront cancer, which is the enemy of human beings.

Is it really feasible?

Please enter computer-aided 3D endoscope into a search engine and have a look at our prototype. It is not unrealistic.
