Chapter 163

Chapter 163

Garrett Nordmark remained calm, first recalling the principles of ultrasound. To be honest, ultrasound examinations were the domain of the imaging department. As a former emergency doctor from another life, he only needed to remember which symptoms warranted an ultrasound, and which situations required what kind of examination.

As for the examination results?

They were all written on the report; even the images on it didn’t require his personal identification. If he could see well, great; if not, it wasn’t a big problem.

As for the principles of ultrasound?

He vaguely remembered reading about it in "Medical Imaging," but if it weren’t for the memory enhancement during his transmigration, he might not recall what the book actually said.

Hmm... Garrett slowly flipped through the pages of "Medical Imaging" in his mind. Luckily, the first chapter had the information he needed.

Ultrasound utilizes 1 to 10 megahertz ultrasound waves, propagating through human tissues. When passing through different organs and tissues, including layers of normal and pathological tissues, each interface reflects and/or scatters the waves to varying degrees due to the different acoustic impedance on both sides.

The echoes or scattering formed by these reflections, along with attenuation information from the ultrasound passing through different tissues, are received, amplified, and processed. On the screen, they are displayed as images or waveforms, creating a sonogram.

Garrett recalled the echo magic. The step of displaying images or waveforms on the screen was directly accomplished by the meditative environment of a mage: it was as if the mage temporarily gained "eyes" like a bat, directly "seeing" the shapes depicted by the echoes.

Thankfully, meditation could handle the process of "seeing." Otherwise, in this medieval-like technological environment, he had no idea where to find a display screen, let alone a computer.

Next up was the matter of "emitting ultrasound waves." Oh yes, he needed to find a coupling agent.

During previous ultrasound examinations, they had to apply a coupling agent to the patient’s skin and press the ultrasound probe against it. Without this, excluding the air around the ultrasound probe, medical-grade high-frequency ultrasound waves couldn’t transmit into the human body.

"Bernard! Come shave the rabbit!"

Garrett shouted loudly. The barbarian ran over, and Garrett handed him the task, while he went to look for an alternative to the coupling agent.T0pp novel updates at novelhall.com

Water... No, it’s not viscous enough; it would flow off instantly.

Alcohol... No, it’s not suitable. It has a similar viscosity to water and irritates the skin.

Aloe vera gel... Sticky, with flow, seemed plausible. The problem was, it was winter, and where could he find aloe vera gel?

What about glycerin?

Garrett surveyed his laboratory and sighed. In the considerable time since he transmigrated, he had been busy with this and that, and he hadn’t gotten around to making glycerin.

This has to be made quickly! Garrett silently added a note to his experimental plan and continued searching. Glycerin was out of stock, how about soybean oil? Olive oil? Rose oil? Wait, why did I have rose oil in my box?

"Garrett! The rabbit’s fur is shaved!"

Garrett’s face twisted and twisted again.

Fortunately, most of these oils were not purchased by him; some were spoils of war, some were obtained in the name of experimental materials from the Magic Council, and some were left here by mages who came to help. Once the experiments were done, they all became his.

If he had to buy and use them now, Garrett would immediately go bankrupt.

After a round of experiments, sweet almond oil seemed to have the best effect. However, he could only vaguely "see" the rabbit’s bones. Garrett sighed:

He had no way to improve the coupling agent on this technological path anymore. Otherwise... Increase the intensity of ultrasound waves?

Adjust the spell model!

Increase output power!

Uh-oh, the rabbit is vomiting blood...

Garrett was bewildered. He stopped releasing the magic, and Bernard let go of his hands. The grass rabbit lay under the cage, its legs kicking weakly, trying to get up but lacking strength. Blood oozed from its mouth in waves. Garrett stared at it for a while, and the rabbit’s head tilted to the side, breathless.

Dead?

Did the excessive power of ultrasound waves kill the rabbit?

Is it the fault of the ultrasound?

When in doubt, dissect and see. Garrett lifted the dead rabbit onto the operating table, rubbed his hands together, and started cutting. Bernard followed along, handing him knives and scissors, watching Garrett cut fur and bones with clinking sounds. Suddenly, he asked:

"So, tonight... are we having roasted rabbit?"

Garrett: "..."

So?

What so?

So, am I doing ultrasound experiments to prepare a rabbit for you to eat?

Wait until I figure out the cause of death before we think about eating!
