Chapter 736: Let’s do magic CT... What, do we need to change the algorithm? (Push up to 10,000-word update 3/3)
Grete did it once when he was trying to catch a duck on a shelf when doing t-shirts for people.
It was still on the Black Gate Peninsula, close to the Great Wilderness. The barbarian nicknamed Old Hunchback swallowed a spoon. In order to determine whether the handle of the spoon was inserted into the blood vessel, Grete had no choice but to perform a very low-precision T.
That time, everyone cried when they heard it, and sad when they saw it. The old hunchback asked him to be tied to a chair and not allowed to move. He put it on the floating dish and slowly rotated it. Turning an angle, Grete manually recorded a batch of data, and then turned another angle. , record another batch of data...
By the time the data recording was completed, it had been two hours of hard work. The poor old hunchback's bladder was about to explode, and Grete had to manually handle it for him.
It is obviously impossible for a mouse to remain still for two hours in its natural state. Gretel dragged a chair, sat down next to the center of the mage tower, and looked at the mouse:
What method should be used to stop it? Tie it up? Should it be injected intravenously with 2% pentobarbital sodium solution? Or intraperitoneally with 10% chloral hydrate solution?
Don't think about it, there are no anesthetics, not any of them...
Grete's first attempt was to tie the mouse up with vines and hang it in the air. Without turning on [Detection Magic], with the naked eye, he could see the mouse struggling and twisting desperately among the vines, with its four little claws digging incessantly.
This definitely won't work. If you don't stand still quietly, let alone say "t", even an x-ray won't show it.
Hmm... How about we confine the mice?
Gretel tentatively threw [Tranquility]... very good, the mouse did not move. Then, he threw [Detection Magic] again.
Perfect!
The shadow of the bones can be seen clearly under the light of X-ray, ah no, [Detection Magic]!
He asked the invisible servant to bring a shelf, hang the rat on the shelf with its tail facing up and its head facing down. Place it in the center of the floating saucer and give the order:
"Touch SS, you let the invisible servant rotate this floating disk as slowly as possible! Well, one degree per second, one circle every six minutes, keep rotating evenly!"
"No problem, boss!"
Taling answered flatly. Of course, the factory settings of Mo SS were like this. Although he learned to tell jokes, talk back, and even learn to hurt him, he never learned to fluctuate in his tone. Grete didn't care, and took out Golden Treasure Box:
"Touch SS and connect this box to the center of the mage tower."
"Okay, boss."
"Save all the images I sensed. Well, how often can you save them? Can 0.1 seconds be enough? Is the image accuracy high enough that a target of 0.5 mm can be seen clearly?"
"No problem, boss."
The tower spirit's voice remained unwavering. Gretel took a deep breath, fixed the oak staff on the opposite side, and activated [Detection Magic]:
"Three, two, one, start!"
In the world of meditation, a picture similar to an X-ray film lit up with bright light, and then passed through the golden treasure box, flowing into the center of the mage tower, and was silently stored.
Grete secretly sighed. Once upon a time, when he had just come to this world, he could only try to take an X-ray. After so many years, he has accumulated enough resources, and he can already try to do it:
There was no golden treasure box to turn the meditation images into real images. He would be so tired that he would vomit blood if he only relied on hand painting;
Without the technology to connect the golden treasure box to the center of the mage tower, relying solely on chips, accumulating resources will make him bankrupt;
There is no mage tower to store data, and there is no tower spirit to calculate. If he relies on himself to calculate, he will definitely calculate until death...
And now, after one round, another round. After three rounds in a row, enough data has been accumulated. The mouse is released from the spell and placed in a corner. It is given a soothing spell to let it eat and drink water on its own. Grete holds the notebook in his arms.
, sat next to the center of the mage tower:
"Touch SS and bring up the image, just one."
An anteroposterior radiograph of a mouse was projected on the wall. Grete pointed to the anteroposterior radiograph and explained to SS:
"Touch SS, from white to black, how many brightnesses can you discern in total? Can they be divided equally?"
"Boss, how do you divide it equally?"
It's over. Gretel slapped his head with a crisp sound. Although touching SS can chat with him and help him handle affairs, its essence is artificial intelligence!
The characteristic of artificial intelligence is that if you don’t know it, you won’t know it. Even if the artificial intelligence can learn by itself, you have to teach it first...
So, how should this brightness be defined?
He murmured, reviewing from high school physics to college physics, and then to "Medical Physics". Coupled with some messy fragments of knowledge, he finally deduced a method:
"To touch SS, you find a non-luminous wall, preferably a white wall. In the dark, define the brightness as 0, then use the brightest white light you can to illuminate it, and define its brightness as 255.
"
The display screen in the center of the mage tower flashed, then flashed again, emitting a piece of white light, and then completely extinguished. Then, a line of words was printed in the white light: 255. It went out again, and a line of words was printed on the black screen: 0.
Okay...that's okay too. Gretel continued to give orders:
"You reduce the brightness of the brightest white light by half...or half the energy, and illuminate the wall. Then, the color obtained is half of the brightness. Divide the two equally, and so on. Is this possible?"
The display screen flashed rapidly. Grete almost thought he heard the sound of the hard drive "creeping". Soon, a square flashed on the display screen:
16 rows, 16...probably 16 columns. Grete looked at it for a long time, but could not see how many vertical grids were divided into each horizontal row...
He belatedly remembered a sad fact: the human eye has its limits. There are only 16 levels of gray that humans can distinguish...
"Touch SS, can you distinguish these brightnesses?"
"Sure, boss."
"Can you discern these different brightnesses in the images you recorded?"
"Sure, boss."
Thank God... Gretel breathed a sigh of relief. The information received by the meditative vision is different from the human eyes. Although the eyes cannot distinguish it, the information is faithfully translated through the golden treasure box and recorded by the center of the Mage Tower.
If you can distinguish it, you can make CT images with high accuracy!
Guchan
Grete continued to give orders:
"Okay, touch SS, you cut the image you recorded into small grids of 0.5 mm by 0.5 mm, and then label the brightness of each small grid with numbers."
This time, the tower spirit was silent for a longer time, so long that Gretel almost thought that the tower spirit was broken... or stuck. Alas, some sound is also good, such as the hum of the hard disk, such as the rotation of the fan.
Voice……
Overthinking, this is the center of the mage tower, and there are no such sounds. It is not impossible to simulate it by touching the SS, but when it is working hard, do you still have to give yourself some sound effects to tell yourself that it is working hard?
Why bother if it drags down the computing power?
Gretel poured himself a cup of tea and sipped it slowly. He drank tea and ate biscuits. It was not until he finished two cups of tea and a plate of biscuits that he heard the sound of touching the SS:
"Boss, that's it."
"...Very good. Then, touch SS, and you take this picture..."
He waved his hand gently. In the void, [Silent Phantom] pulled out a cube, and the cross-section inside was divided into countless square boxes. Then, the vertical image was opened 360 degrees with the center of the cross-section as the axis:
"The data of each point in each picture is marked. Calculate the sum of the data of each point, find the average, and restore it into an image according to the corresponding light and dark. Finally, stack them one by one to make a three-dimensional image
.Is that okay?”
"Okay, boss. It takes time, boss."
"Okay, I'll leave it to you."
He touched SS and began to calculate silently. Gretel rolled up his sleeves and began to do his part:
Dissect the mouse.
Well, according to the fixed operating procedures, grab the tail with your right hand and lift it up; press the head and neck of the mouse with the thumb and index finger of your left hand, and press down; grab the base of the tail with your right hand, and wrap the tail around your fingers in a circle, one, two, three
, pull hard!
Bang!
Beautiful, and the execution was neat and tidy. I haven’t given up on my previous experiments with mice!
Grete gave himself a thumbs up and began to dissect. Following the previous surgical approach, he cut the skin, cut the muscle tissue, and exposed the ribs. Remove the wires on the ribs and the wires on the spinous processes...
Pick up the mouse and use [Detection Magic] to take a picture of the front view and a side view. There is no obvious change in the scoliosis angle, indicating that the scoliosis is structural and has been completely developed. Okay, take out the spine.
, start looking at pathological changes!
Gretel "clicked", "clicked", and made a knife at the cervical vertebra, and a knife between the lumbar vertebra and coccyx. Then he cut the ribs and took out the spine.
When you pick it up, you can see that the spine is centered on the top vertebra, and the vertebral body is curved sideways on the coronal plane, lordotic on the sagittal plane, and rotated on the longitudinal axis. It is obvious that it has rotated into a three-dimensional S shape.
"Touch SS! Record the shape of this spine!"
It's broken, there is no response when touching SS, and it gets stuck when touching SS... Is there too much that needs to be calculated, and I still haven't figured it out yet?
Grete reached out and gently touched these vertebrae, trying to keep these deformations firmly in mind. This is what you have to deal with, and this is what you have to treat in the future.
See clearly its condition and all its changes, and don’t let down the sacrifices of these experimental animals!
Grete picked up the scalpel again and continued to dissect in detail. After removing the muscles next to the spine, he could see at a glance that the epiphyseal plate on the concave side of the vertebral body was thinning, and the cortex and trabeculae were thickening. And on the protruding side, the epiphyseal plate was thickened.
The strain becomes finer and thinner, and obvious organic changes have occurred.
Um……
If it is on the human body, how should it be corrected?
【Mage Trick】!
Gretel pinched out an object with the same shape and rough material, then trimmed it bit by bit and added it bit by bit. Cutting, patching, trimming, patching, the fragments were flying in front of him, and the S-shaped twisted spine became erect bit by bit.
"Okay... now we have to see how this kind of repair can prevent damage to the spinal cord and nerves..."
If you want to avoid damaging these things, CT is the most basic. In theory, you should also get MRI, but NMR...
He still doesn't know what to do...
Gretel straightened up and stretched hard. But it was finally done. If he couldn't get it right again, he felt like he was going to have a herniated disc:
"Touch SS, are you okay?"
"It's almost...alright..." The voice of Touch SS kept getting stuck, as if he was still making difficult calculations:
"Boss... give... me... some... time..."
This speed is too fast! An hour has passed since I finished this wave of research, but the 3D reconstruction report hasn’t come out yet!
In the previous life, a chest scan would result in a report from the emergency department in 15 minutes. The chest of mice is much smaller than that of humans, and it still hasn't come out yet?
Gretel finished cleaning up the mess, drank a glass of milk, and ate two small biscuits as a midnight snack. Then he turned around and touched SS to finally project a three-dimensional image in front of him. Gretel only glanced at it and frowned tightly.
frown:
Tsk, this still doesn’t work!
It's so blurry that the edges of organs and bones can't be seen clearly at all!
The speed is slow and the images are blurry. For this magic CT, the algorithm must be iterated!
Definitely need to iterate hard!
Alas, he really can't write algorithms... I'll go to Mrs. Alva's tomorrow and ask if there is any magician who is good at training artificial intelligence?
