Color coding tissue

In this video professor Quyen Nguyen brings up an interesting critical aspect between text-books used for learning and reality. In usual text-book illustrations different types of body tissues have different kinds of colors, e.g. different colors of the blood vessels. In reality it looks quiet different as she tells it is difficult to tell where the nerves are and one has to learn to distinguish between veins and aries. In a surgery it leads to the problem that nerves might not be recognised completly in the surrounding tissue and suffer damage. For the patient this leads to e.g. pain later on or incontinence (dependent on the type of sugery).

New developed molecules mark different kinds of tissues like nerves or tumor cells. The so marked tissue appears in a fluerescent color. In surgeries it this would help to avoid nerve damage as the nerve cell is clearly distinguishable from the surrounding tissue (like in a text-book) and e.g. in case of cancer the all affected tissue presented in fluerescent colors can be cut out.

I’m wondering if it is usable for all kinds of tumors and how long the effect lasts.

The problem behind the invention presented above, that is to distinguish between different tissues during surgery, should be considered in other inventions in healthcare asa well like the following. You may know the interaction table used for games mostly or cooperative tasks like logistics. In this video below it is used as support for a virtual surgery. The table presents a human body in life-size and the user can interact with it, make different cuts and can rotate the person.

In the video it seems that the presentation is a 3D model and not a photo-realistic presentation of the human body, e.g. blood vessels have a different color which is not the case in the body. Considering the first presented video, would it not be a good idea to present the body photo-realistic so the students can practise e.g. identification of veins, aries and nerves? Taking the idea one step further different visual presentations could be used adapted to the user’s knowledge, starting with an illustrative presentation which helps to easily identify details up to a photo-realistic one.

The boundary condition of the virtual table seems that it can help to study the different tissues of the body, to detect specific objects and maybe also to practise teamwork partly but e.g. not the surgeons dexterity or emotional feedback.
