170
Q

In this section, we explain how the Korean industry-leader 365mc adopted AI technology in the healthcare sector. In this realm, AI-based solutions can be extremely effective in discovering and healing disease, simulation education, surgery development, and more. 365mc is famous for?

A

providing dieting and liposuction treatments for patients to have a healthier life beyond focusing only on body shape.

Recently, 365mc YEAR combined AI technology with liposuction. Specifically, liposuction is a surgery that removes fat from the human body with a cannula—a tube that can be inserted into the body.

171
Q

365mc’s M.A.I.L. System leverages IoT technology to bring data together from?

A

the sensor of the cannula that drains fat and the movement of surgeon and uses machine learning technology to pattern and analyze collected data from the surgery.

172
Q

In fact, extracting fat is an extremely complex surgical procedure.

A

In particular, the cannula must precisely reach the fatty tissue between the skin and the muscles.
If not precisely done, the cannula may damage muscle tissue if it is injected into deeper tissue.
In addition, the fat may be removed unevenly or skin necrosis can occur if the cannula is not sufficiently inserted. Therefore, the skill of the surgeon is essential. In fact, the process of injecting a cannula and extracting fat occurs 12,000–20,000 times per surgery.
This fact means that moving a cannula in a uniform manner is critical.
Nevertheless, every patient may have different types of fatty tissue and different areas being operated on.
Owing to the complexity of the procedure, a skillful surgeon with vast experience is highly recommended.

173
Q

In this context, 365mc had an idea to digitize the liposuction procedure by ?

A

leveraging motion capture technology. Such digitalization is necessary for raising the precision of the surgery, checking the progress after the operation, and providing the direction for surgeons to assure the high level of the operation.

174

175
Q

Technically speaking, 365mc employs a special cannula having :

A

the motion recognition sensor.
This sensor keeps reading the activity of the surgeon’s hands in real time during the liposuction procedure.
The motion recognition sensor detects the trace of the cannula through correctly fusing readings from an accelerometer and a gyroscope.
Exactly 180,000 data entries can be generated per surgery, as one cannula movement makes nine types of data where the cannula moves a maximum of 20,000 times per operation.
To store and process this massive amount of data, Microsoft Azure IoT solution accelerators store is incorporated.

176
Q

The M.A.I.L. System significantly changes the liposuction of 365mc:

A

-from depending only on a surgeon’s sensitivity to relying on data.
-Moreover, the M.A.I.L. System helps to create awareness of abnormal cannula movement immediately, allowing for the preparation of side effect countermeasures directly after the procedure.
-Overall, the M.A.I.L. System increased both the accuracy and safety of liposuction surgery.

177
Q

In the future, 365mc looks forward to further advancing its systems with Microsoft Azure Machine Learning. An example of the futuristic plans of 365mc (n.d.) is ?

A

medical inspections, data logging, identification/tracking, while keeping the IEEE 802.15.4 radio OFF for most of the time. Accordingly, the battery lifetime of the HS nodes is highly maximized.

194
Q

At the IoT smart gateway, the monitoring application sends notifications to inform the nursing staff about the patients’ location, i.e.,?

A

the last position where the RFID tag has been read, and their health status.

195
Q

In fact, the collected data is sensitive and confidential, hence?
