There are many people, which brings a problem. The CT film is too small and inserted into the reader. The people in front can see clearly, but the people in the back can't see it at all.

Chen Xia counted the densely packed heads in the conference room. There were at least 100 doctors. It can be said that all the doctors in the clinical department were here, including many department directors or old experts.

They are also very interested in the hospital's introduction of the second CT machine in the province.

Moreover, the role of CT machines is not limited to respiratory and cardiothoracic surgery, and is of great significance to neurosurgery, general surgery, orthopedics, enthalpy, even gynecology, and gastroenterology.

Dean Gu was speechless when he looked at the small video reader on the podium. Not to mention the end, the doctors in the middle couldn't see it.

"Xiaoxia, come here, is there any way to enlarge this movie? Let everyone see it?"

The young doctors behind were also cheering: "Old Chen, hurry up and think of a solution. Even if I hold a telescope, I can't see it."

Chen Xia raised his middle finger: "I see you holding a telescope to see the widow next door take a shower, right?"

Hahaha~~~~

The conference room suddenly burst into laughter. Doctors, especially surgeons, like to say dirty jokes. This not only allows you to relax, but also allows you to tease the young nurses.

When the doctor was silent in the operating room, sweating heavily, and his eyes were staring like light bulbs, he would definitely be finished.

Either the operation is more difficult than imagined, or the lesion organs are no longer touched, or the operation is not acceptable at your own level, in short, nothing is good.

"Okay, you all wait for me, the immortals have their own tricks."

After saying that, Chen Xia ran out of the conference room, hid in the General Affairs Department, and got into the space hospital.

There are everything in science and education, such as physical projectors and white curtains, which are all essential tools for teaching.

Chen Xia took out one. This physical projector is actually a video shooting mode. If you put the film or paper prepared in advance on the flat, the content under the lens will be projected onto the white screen, which is very convenient and practical.

After Chen Xia returned to the conference room with the machine in his arms, he specifically asked Wu Shaochen and Xie Liping to help him cut out those CT pictures one by one.

He took out a CT film and put it on the projector. He turned on the light switch. The CT film placed after it was immediately displayed on the white screen, which was very clear and made everyone exclaim.

Even Dean Gu couldn't help asking: "Where did your machine come from? Why haven't I seen it before? It's so easy to use."

"Well, I should have bought it from Hong Kong. Now only Japan and Moldy Country can be found. If you can't buy it in China, don't think about it. Come on, let's go to class for the official."

Everyone stared at the white curtain at once, and everyone took out their notebooks and prepared to record them carefully.

"First of all, what I show you is a normal chest CT image. We can see that the patient's chest is symmetrical on both sides, the ribs are walking normally, the lung textures on both sides are walking normally, there are no space-occupying lesions, and there are no inflammatory exudates.

The blood vessel bundles in the bronchial tract of the lungs did not increase, thicken or disorder. There were no abnormally enlarged lymph nodes in the mediastinum. The trachea and the main bronchials on the left and right showed patency. There was no thickening or adhesion on both sides of the pleura. The heart and the large blood vessels were located as normal, and no abnormal dilation or stenosis was seen. The bone density of each component of the thoracic tract was normal.

Normal chest images can not only see whether the patient has lung lesions and pleura lesions, but also roughly indicate whether there is any problem with the mediastinum. Therefore, chest CT is the preferred imaging method to prompt lung diseases, because it has a high resolution of density, and most of them can be found through chest CT examination."

While Chen Xia was talking, he started drawing chest anatomical pictures on the blackboard.

"To see chest CT, you must first know the functions of the lung window and mediastinum window. In order to remember the anatomical name, because the tissue structure composition of the lesion site is an important basis for judging the disease tissue category, you need to understand the anatomical structure as skillfully as possible and achieve accurate positioning. Then you can continuously observe the division of the lung lobes from top to next layer."

Chen Xia changed a CT film at this time, took a broom handle as a teaching stick, and lit a point on the curtain and said:

"You see, this is an anatomical diagram of the bifurcation level of the trachea. Here is the upper right upper right pulmonary vein, this is the posterior branch of the right upper pulmonary vein, this is the right main bronchus. Change to another piece, this is the posterior branch of the upper left lobe, this is the left main bronchus."

Then Chen Xia took out different CT films and told everyone about the basic CT anatomy structure.

For example, "the bronchial level of the right upper lobe", "the middle section of the left main bronchial", "the bifurcation level of the left upper lobe and the tongue section", "the opening level of the right middle lobe", "the upper level of the aortic arch", etc.

The entire conference room was quite quiet, with only the rustling sound when the strokes passed through the paper.

Chen Xia spoke faster because there was too much content. In his previous life, he taught interns and trainees in the department, he just took out a film and told the specific cases of this film.

But in the current explanation of the film reading, although everyone has anatomical knowledge, they have no foundation for CT film reading, so they have to start with the most basic things, which cannot be finished in one or two hours.

Finally, I talked about it from 6pm to 12pm and it didn't stop yet.

Chen Xia had actually been exhausted for a long time. This is not a live streaming online sales. She could talk nonstop, and then she claimed that she had bought hundreds of millions of dollars in one night.

His mouth was completely dry. Chen Xia looked at the young doctors who took notes seriously and felt very helpless. Why wasn't anyone with eyesight?

When he loosened his collar again and was a little hot, Gu Lin handed over a thermos cup in time, smiled slightly, and even raised his hand and shouted softly, "Come on."

Sitting at the end of the conference room, Gu Lin was already full of pride when she saw her husband so wise and powerful. After all, she was a couple. When she saw Chen Xia’s movements constantly, she knew that this guy was tired, thirsty, and a little impatient.

So I quickly made the "ginseng and wolfberry tea" and handed it over to the right time, so that I could definitely act like a "good wife and mother" in front of others.

Chen Xia looked at his watch and coughed a few times: "I said everyone, I have to go to work tomorrow, so we'll end it now? I still have to go back to Ke Town."

"No, no, Chen Laoshi, can you tell me more about the distinction between inflammatory pseudo-tumor and lung cancer yesterday? We didn't hear it yesterday."
