The New Tech for the Disclosure of Our Body

ModesTable2_4k

Summary:

Researchers , at The University of Queensland and CUDOS, have invented the echo-less light source which facilitate the development of the medical image. The technology is about using multimode optical fibres, hair-thin endoscope, to transfer the light. Normal speaking, the light travelling the multimode optical fibres will be scatter. However, based on the Eisenbud- Wigner-Smith states, proposed a long time, this state allows people to deliver a short pulse to the distant end of the fibers. This state is to allow light travelling through the computer without decohering in order to reduce the echo.

Opinion:

What is the important of the medical imaging? The importance of if  is for capturing the image of body without the intrusive surgery. Indeed, nowadays, we have already got many good innovation of the medical imaging, for examples, CT, MRI and ultra-sound . Unfortunately, those of them have a great limitation and disadvantage. For looking more clearly, researchers are going to put the EWS states into practice. The EWS states are going to provide a echo-less light for imaging.It allow the doctor reach the inaccessible regions the our body, such as brain. The proposed tech has no radioactive feedback which won’t cause abnormal cell- differentiation after scanning. It is going to bring a new tech- world for medical area.

A New Creature for Imaging – Total-Body PET Scanner

Summary:

What is the biomedical technology going on?  In these days, scientists and engineers are working together on how perform better imaging in diagnosing diseases. Imaging – a critical technology for diagnosing, is the most helpful technology to investigate what wrong in our body without cut t off. The Berkeley Lab planned to build the first total-body PET scanner. Why we need a total-body PET scanner instead of segment PET scanner? It is obvious that for the better safety for the patient. The total-body PET scanner can reduce the time taken for radioactive scanning in order to reduce the dose of radioactive substance that the patient take.

My opinion:

What is the responsibility of biomedical engineering for the future? In fact, we are as great as the medical officers. We are developing the latest tech to help and relieve the pain of the patient. As for this total-body PET scanner, the focus is to reduce the dose of radioactive substance taken by the patient. The engineers are going to reduce the time from 20 minutes to 30 seconds. As for the aim of medical treatment, it is to prevent and reduce the bad feedback for the patients.

New Innovation for Surgery

Summary:

It is a good news that prostate surgery can be taken under the scanning of the MRI. It is a boon to the patient that surgeons can cut off the abnormal cells carefully on order to reduce the chances of having the same illness. In this innovation, scientists have developed the non-metal apparatus during the surgery. It prevents the disturbance of the MRI based on the magnetic properties of the tools.

My opinion:

As for the patients, we should develop the better tools for them. For the accuracy of curing the abnormal cell, medical imaging is the helpful hands. During the surgery, the surgeons are difficult to detect the abnormal cells by their naked eyes. They should rely on the MRI to take good care of the patient.

The Cancer-Cells’ Detector- Sound Wave

sorting-cells-with-sound-waves

Summary:

Cancer cells – the bigger enemy of human , are now easier to be discover and detected by the doctor which is because the help of biomedical engineers. The application of titled sound wave are going to sort out the cancer cell from the blood cells without any damage of the cell. In the previous time, people use chemical or damaging force to sort out the cell which is not completely reliable. Due to the above, scientist and engineers are plan using sound wave for sorting. However, it requires a long developing path based on one problem – difficult to detect the change of trajectory of cells. Until now, thanks to the titled sound wave, we are much easy to detect the trajectory of cells in order to separate the cells.

My opinion:

It is a great idea for using sound wave to sort out the cells. According to the article, for an example, 71% of breast cancer cells are disclosed mixing up with white blood cells in lab. it is difficult for having a treatment to kill the cancer cell directly without destroy other healthy cell. However, in the coming future, we can sort out different cell due to the difference of the size of cells ,compressibility and density and the angle of the sound waves when passing the microchannel. For treatment of cancer cells, titled sound wave is a milder way to cure patient and release their pain.
