Chapter 1598 【1598】CT Doctor Is Not Easy

"Our classmates all said that Teacher Qin is beautiful and capable." Xie Wanying said with honey on her lips. Besides, what she said was the truth, Teacher Qin is a super beautiful big beauty.

Teachers like sweet-talking students. Dr. Xu smiled and took her arm: "Come on, I'll take you into the control room and have a look."

The master teachers can see at a glance the small calculations in the heart of a student like her. Dr. Xu and Mr. Qin are the same age, Mr. Qin is a big boss, and Dr. Xu is also a big boss.

Xie Wanying thanked her repeatedly, and followed Teacher Xu like a little follower.

In the control room, young doctors are operating. Dr. Xu came in as a senior doctor 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 earlier, performing CT for patients also requires the skills of doctors in the CT room. Especially for the investigation of difficult cases with hidden lesions, the technical level of auxiliary departments such as CT is very important.

Doctors in the CT room have many things to do, and the technical level is reflected in all aspects. First of all, the reason why ct is called tall is that it is definitely a big step forward in technology than x-ray. The former is a cross-sectional scan, and x-ray is a single-plane scan. When images scanned in a single plane come out, various tissues of the human body on one plane will be stacked together, making it difficult to distinguish some lesions. The doctor's film reading is greatly disturbed and error-prone.

CT cross-section is a multi-level scan to avoid tissue overlap and capture fine lesions. At the same time, the difficulty is that multi-level scanning means multiple images appear. According to the fineness of the inspection, it is generally called the layer thickness of CT scan, that is, how thin the human body tissue is "cut" into layers for scanning. The thinner the "cut", the more layers are separated, and the total number of scans There must be more images and pictures. CT scans can have as few as a dozen pictures of a part, and as many as hundreds of pictures. All these images need to be read manually. Doctors in the CT room need to select problematic images from a large number of images for processing to enhance the display effect of lesions.

Generally, the CT reports obtained by clinicians and patients are printed out by the doctors in the CT room carefully selecting the key pictures with problems. If you want to see the original scanning data, both clinicians and patients can go to the CT room to apply for copying the original data in the computer.

After understanding such a program, you can know that doctors in the CT room need to find valuable lesion pictures from massive data, which is equivalent to digging gold from the sand. It is impossible without years of training and accumulation of knowledge and experience. Before digging gold in the sand, doctors in the CT room need to suspect which sandy area the gold may be hidden in, and it is impossible to dig indiscriminately. CT radiation is much stronger than X-ray, if no lesion can be found, it will bring harm to the patient. For this reason, before scanning, doctors 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 to the CT room. Here is a summary of the condition and the direction of the clinician's suspicions about the patient's disease. The doctor in the CT room reads the application report with his own experience, and then sees whether it is necessary to adjust the CT scan plan proposed in the clinic.

In layman's terms, when the clinician says to use the machine to scan, the doctor in the CT room needs to help the clinician review it, and scan what should be scanned. When other abnormalities are found in the patient, help the clinician to focus on scanning. .
