"All our classmates say that Teacher Qin is beautiful and capable." Xie Wanying said with honey on her lips. Besides, she was telling the truth. Teacher Qin is a super beautiful girl.
Teachers all like sweet-mouthed students. Doctor Xu smiled and took her arm: "Come on, I'll take you into the control room to have a look."
Big boss teachers can see the inner calculations of a student like her at a glance. Dr. Xu and Teacher Qin are the same age. Teacher Qin is a big boss, and Dr. Xu is also a big boss.
Xie Wanying thanked her profusely and followed Teacher Xu like a little follower.
In the control room, young doctors were operating. Dr. Xu, as a senior doctor, came in and stood behind to give guidance: "Dr. Zhao, have you studied the patient's examination application report clearly? Do you know what problems need to be focused on?"
As mentioned before, performing CT on patients also requires the skills of CT room doctors. Especially for troubleshooting difficult cases with hidden lesions, the skill of auxiliary departments such as CT is very important.
There are many things that doctors in the CT room have to do, and their technical level is reflected in all aspects. First of all, the reason why CT is called advanced is that it is definitely a big step forward technically than X-ray. The former is a cross-sectional scan, while X-ray is a single-plane scan.
When the image scanned by a single plane comes out, various human tissues will be stacked together on one plane, making it difficult to distinguish some lesions. This will greatly interfere with the doctor's reading of the image and is prone to errors.
CT cross-section is a multi-level scan to avoid overlapping tissues and capture subtle lesions. At the same time, the difficulty is that multi-level scanning means multiple images are displayed. Depending on the precision of the examination, it is generally called the layer thickness of the CT scan, that is, the body's
The tissue is "cut" into thin layers for scanning. The thinner the "cut", the more layers are separated, and the total number of images scanned will definitely be more. A CT scan can take as few as a dozen pictures of a part, and as many as
It can reach hundreds of images. All these images need to be manually resolved and read. Doctors in the CT room must select problematic images from a large number of images for processing to enhance the display effect of the lesions.
Generally, the CT report sheets that clinicians and patients receive are the key pictures in question that are carefully selected and printed out by doctors in the CT room. If you want to see the original scan data, either the clinician or the patient can go to the CT room and apply to copy it into the computer.
Original data.
After understanding such a procedure, you can know that finding valuable lesions pictures from massive data is equivalent to digging for gold from the sand. It is impossible to dig for gold in the sand without years of training and accumulation of knowledge and experience.
In the past, doctors in the CT room had to first suspect where the gold might be hidden in the sand, and it was impossible to dig randomly. CT radiation is much greater than X-rays, and if you can't find the lesion, you will be exposed to more radiation, which will bring harm to the patient. For this reason,
Before scanning, the doctor in the CT room must first understand the patient's condition.
How to understand the patient's condition, the doctor in the CT room uses the examination application report written by the clinician for the CT room. It contains a summary of the condition and the clinician's suspicion of the patient's disease. The doctor in the CT room uses his own experience to read the application report,
Then see if it is necessary to adjust the clinically proposed CT scan plan.
To put it in layman's terms, the clinician says that the machine should be used to scan where the machine should be scanned. When the CT room doctor gets it, he will help the clinician to review it and scan where it should be scanned. When other abnormalities are found in the patient, he will help the clinician to focus on the scanned area.
