Thinking

Thinking about the future and what I want to major in can be kind of stressful. I've come to a conclusion and that is majoring in Psychology. From having an Associates degree in Diagnostic Medical Sonographer I've jumped into Psychology. The reason why I want to study Psychology is because of all the interesting things you can learn about the human brain and peoples way of being. I think it will be something amazing to learn and all of the different people I will learn about and be able to meet. I've read many things about students taking these classes and how they are enjoying them. I want to start already but first I must get my Ultrasound license and have that as my back bone than start with Psychology. I am very dedicated to this and nothing is stopping me from doing it. I feel happy now that I have finally figured  everything out now I can relax :)

Ultrasound Physics Chp. 1

1. Give the units of measure for each term:

-Wavelength: mm, cm

-Frequency:1/sec, Hz

-Intensity: watts, sq cm

-Propagation speed: m/sec

-Period: sec, usec

-Power: watts

2. Which determines each of these parameters, the medium or the US system?

-Wavelength: both
-Frequency: sound source
-Intensity: sound source
-Propagation Speed: medium
-Period: sound source
-Power: sound source

3. Which of the following can not be changed by the Sonographer?

-Wavelength, Propagation speed, Period

4. Acoustic Variables are:

-Density, Temperature, Pressure and Particle motion

5. How many cycles occur in 0.5 seconds if the frequency is 5 million Hz? 2, 500, 000 cycles

6. What is the acoustic velocity in soft tissue? 1,540 m/s or 1.54 km/sec

Tutoring

I am being tutored by my ultrasound teacher at her house with four other students. The classes are in spanish. At first I thought I wasn't going to comprehend but it turned out that I understand everything just like I would in English. Today we went over chapter one and two I soaked it all in and I wasn't lost at all. I can't wait for the next class I am so happy I am that much closer to taking my exam.

Here are something's I want to go over, it is something I need to remember.

- Frequency and Period: Inversely related and Reciprocals

- Power and Amplitude: Directly related

- Intensity and Power: Directly proportional

- Intensity and Amplitude: Intensity is proportional to the waves amplitude squared


- Wavelength and Frequency: Inversely related

- Stiffness and Speed: Directly related

- Density and Speed: Inversely related

- SPL and Frequency: Inversely related

- SPL and the number of cycles per pulse: Directly related


- SPL and Wavelength: Directly related


- PRP and Depth of View: Directly related


- PRF and Depth of view: Inversely related


- Distance and Attenuation: Directly related


- Frequency and Attenuation: Directly related

Anxiety

I haven't been writing lately on my blog. A lot has happened this past month I don't even know where to start. One thing I have learned and I have realized is that a lot of people have anxiety. Me myself I suffer from anxiety and it is something a lot of people may not realize they have. Most people with anxiety tend to be more hyper and antsy than others. For example my brother suffers from being very hyper active and tends to want to do so many things all at once and doesn't even know where to begin. I am also the same way. The only difference between me and him is that we have different ways in trying to relax our selves and try to calm down. He tends to try and ease himself with things that he shouldn't be calming him self down with, doing that it starts to become an addiction and it can lead to worse things. Me in the other hand I have anxiety but not all the time like my brother. I tend to show my anxiety when I am about to start an interview for an employer or when I don't feel I am being productive or I want to achieve something and I try so hard that I mess up. Anxiety happens to all of us at one point in our lives and I feel it is something we should all learn about so we can try to be more relaxed in ways where it won't affect us. I am writing this because I feel I should share it and maybe it can help people. Basically what I am trying to say is my brother has always been very hyper since he was very little and when you are a child sometimes you disregard that your child is so hyper because you just think he or she is young and full of energy but they might always be that way and as they get older you can realize that they might have some sort of a problem and you can try to guide them in the right way and know how to help them from the start.

Kidney

The kidneys are a pair of organs located in the back of the abdomen. Each kidney is about 4 or 5 inches long -- about the size of a fist.

The kidneys' function are to filter the blood. All the blood in our bodies passes through the kidneys several times a day. The kidneys remove wastes, control the body's fluid balance, and regulate the balance of electrolytes. As the kidneys filter blood, they create urine, which collects in the kidneys' pelvis -- funnel-shaped structures that drain down tubes called ureters to the bladder.

Each kidney contains around a million units called nephrons, each of which is a microscopic filter for blood. It's possible to lose as much as 90% of kidney function without experiencing any symptoms or problems.

Spleen

The spleen is an organ in the upper left side of the abdomen. It filters the blood by removing old or damaged blood cells and platelets. It also helps the immune system by destroying bacteria and other foreign substances. The
spleen holds extra blood that can be released into the circulatory system if needed.

Liver

*Three major functions of the liver are :
- It cleans your blood.
- It produces an important digestive liquid called bile.
- It stores energy in form of a sugar called glycogen.

Indecisive

Looking at the ARDMS licenses now I am confused. I want to get the ARDMS and be able to work in any specialty, but I see that for vascular there is a totally different license required. The job I would be getting for sure is requiring Vascular so I might just take the vascular exam and be certified for VRT and than before five years I must apply for the official ARDMS that way I can get abdomen and OB/GYN. AHH going nuts!
