"All of my classmates say that Teacher Qin is pretty and capable," Xie Wanying said with a hint of honey on her lips. And what she said was the truth. Teacher Qin was a super pretty lady.

Teachers all like students who are sweet-talkers. Doctor Xu smiled and pulled her arm, "Come on, I'll take you to the control room to have a look."

The senior teachers could see through the inner thoughts of a student like her. Dr. Xu and Teacher Qin were of the same age. Teacher Qin was a senior, so Dr. Xu was also a senior.

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

In the control room, young doctors were operating. Dr. Xu, a senior doctor, walked in and stood behind to give instructions: "Dr. Zhao, have you studied the patient's examination application report? Do you know what problems need to be checked?"

As mentioned before, CT scans also require the skills of doctors in the CT room. Especially for the screening of difficult cases with hidden lesions, the technical level of auxiliary departments such as CT is very important.

Doctors in the CT room have a lot to do, and their technical level is reflected in all aspects. First of all, the reason why CT is called high-end is that it is definitely a big step forward in technology compared to X-rays. The former is a cross-sectional scan, while X-rays are single-plane scans. The image from a single-plane scan will cause various tissues of the human body to overlap on one plane, making some lesions difficult to distinguish. This greatly interferes with the doctor's reading of the film and makes it easy to make mistakes.

The cross section of CT scans at multiple levels to avoid overlapping tissues and to detect subtle lesions. The difficulty is that multiple-level scans mean that multiple images are displayed. The precision of the examination is generally called the layer thickness of the CT scan, that is, how thin the tissues of the human body are "cut" into for scanning. The thinner the "cut", the more layers there are, and the more images there are. A CT scan of a part can produce at least a dozen images, and as many as hundreds. All these images need to be manually distinguished 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 lesions.

Generally, the CT report films that clinicians and patients receive are the key images that the CT room doctors carefully select and print out. If you want to see the original scan data, both clinicians and patients can go to the CT room to apply for a copy of the original data in the computer.

After understanding this procedure, we can know that it is like digging gold from the sand for doctors in the CT room to find valuable lesion images from massive data. 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 first suspect which area of ​​the sand the gold may be hidden in. It is impossible to dig randomly. CT radiation is much greater than X-rays. If you can't find the lesion and keep adding more radiation, it will cause harm to the patient. Therefore, before scanning, doctors in the CT room must first understand the patient's condition.

How to understand the patient's condition? The CT room doctor reads the examination application report written by the clinician to the CT room. It contains a summary of the patient's condition and the clinician's suspicion of the patient's disease. The CT room doctor uses his own experience to read the application report and then sees whether the CT scanning plan proposed by the clinician needs to be adjusted.

In simple terms, when the clinician tells the machine to scan something, the CT room doctor will help the clinician review it and scan whatever needs to be scanned. If other abnormalities are found in the patient, the doctor will help the clinician scan more key areas.
