My brain

Like to figure things out.  Am never fast, but in single contexts can maintain large amount of state.

Team of resources to help with workload and bouncing ideas, but I mostly like to do my own thing, or dole out independent chunks to others.  

Have high expectations, but TRY to be fair in balancing and shuffling bits to the right people.

Hate training people, and cannot write training.  Can answer questions, research, demonstrate, etc.

Particularly good at finding problems, especially with workflow or tech procedure gaps, but also in unexpected setup and use cases.

Am fine repeating complex tasks until the procedures are refined, but loathe to do repeated simple tasks.

Have decades of experience with AIX system recovery, virtualization, IBM storage, DebIan Linux, mdadm, etc.  Pretty crippled without google or my own build docs to deal with syntax.

Can code in BASH/ksh a bit, and have been proficient in PERL and Object Pascal.  Am not an efficient programmer, so I let most of it fade.

Run Windows desktop (98/2k/xp/7).  Not too content with Mac, Linux or AIX desktop, but can make due.

Too little workload, and I will eplore the intranet, or find some OSS toy, or maybe become a short term expert in something random (pilot, soap, cycling so far).

Too much workload, and I shut down.  Priorities shift, and my work output drops.  Worst with high context shifting, or consistent lack of respect (false justifications, or overt hostility).

Like a lot of flexibility in my schedule.  Some travel is okay. Work from home is great.

Not religious, and not athiest.  Sm my own thing.  Happy to talk politics, religion, etc unless logic is walled out.

Verbose, but I try to simplify emails when I have time.  Often have to talk through something iteratively to figure out what to do.  Mental filtering is some strange, magical thing.

Sometimes have no idea what emotional or other context exists.  Can iterate through and try to define, but not always intuit.

blah blah



MRI terms demystified

SAG – Saggital – From the side. Top of head is up, face/chest are left. backside is right.
AX – Axial – From the top. Face/chest are up. Backside is down. Patient right is right & patient left is left.
COR – Coronal – From the back. Top of head is up. Patient right is right. Patient left is left. First image is front of body.

T1 – Short timing – Pulses (TR or Time of Repetition) are less than 1 second apart. Return signal (Time of Echo) is less than 30ms after pulse. This is weighted for showing proton density (PD), which means fluid and complex molecules.

T2 – Long timing – TR over 2 seconds, and TE over 80ms. This picks up lower density structures better, but rapidly flowing fluid, especially arterial blood, will already be out of frame before the echo is returned. This picks up MS better, because of the high density signal from the plaques and lesions is strongly contrasted by the low signal from the CSF.

FLAIR – Fluid Attenuated Inversion Recovery – Often a T2 image is really a high dynamic range image created from both T1 and T2 echoes. This is used to suppress the CSF signal, while still picking up the details from T1.

Signal differences
Different types of anatomy and pathology return different levels of brightness or darkness. Comparing T1, T2 and FLAIR signal strengths can determine what type of mass exists at a specific voxel (volumetric pixel). This can be compared with reasonable physiology for the area to help provide diagnosis or indication for further assessment.

You remembered 81% of the information in the Memory Test.

You remembered 81% of the information in the Memory Test.

But research shows there's a lot you can do to improve your memory. And if you do, it can help you function in more ways than you'd think. There are 6 main types of memory, which help us interpret and store different types of information. You scored highest in object memory.

That kind of memory allows you to visualize how an object will fit in, or move through space, and where it will ultimately end up. This skill is particularly useful when you're playing sports or packing a lot of objects into a small space. With your strength in this area, you're probably able to visualize where an in-flight ball will land and are likely quite good at completing jigsaw puzzles.
