CT Patient positioning plays key role in radiation dose reduction - good article
"It is successful teamwork between technologists, radiologists & medical physicists that allows good image quality & dose reduction in imaging"
Miscentering affects dose & image quality
i. Effect on dose: 4 cm mag increases dose by 67%
vertical shifts impact organ dose, breast, skin, etc
ii. Effect on image quality: Miscentering of 2.1 cm increased image noise by 6%
Tips:
a. The tube should be positioned at the top of the gantry, rather than at the bottom, to avoid offsets below the isocenter
b. Both AP and lateral (LAT) topograms should be used with the lowest acceptable tube current & tube voltage settings

Strategies to mitigate the despair & speak recovery: 1. Be a detective: You may never get a full explanation, but u need to find out (legitimately) whatever details u can about why ur application was rejected
2. Reassess ur institutional commitment:Will this disappointment be fatal-either to ur career or to ur feelings for institution?...will U be ok, if you remain an associate professor for the rest of ur academic life. If so reaffirm elements of ur job that U love & focus on them

3. Expand your spheres of influence: Maybe one reason your application failed was that U weren’t perceived as well known in Ur field. Time to become more active in Ur discipline's professional organizations. Networking if key.

6 am: Surgical corridor: Medical Physicist stops by the O-arm resting place
Medical Physicist (MP): Hi buddy! I got a call from the surgeon telling me that you are not behaving properly.
O-arm: What are you talking about doc?
1/
MP: Look here, this what I am talking – what is this black hole?
O-arm: About that – well why y’all treat me like a stepchild when compared to my buddy MDCT*?
MP: Why do you say that?
*MultiDetector Computed Tomography
2/
O-arm: Doc, reason for that black hole is simple. No one does calibration on me routinely. I know everyday, techs do air-calibration for MDCT but not for me.
MP: So, it’s that simple – I thought you were misbehaving because someone broke your jaw. Remember, we fixed your jaw

O-arm: Yep, doc. You didn’t notice that I am all fixed. I believe your word meant something to them. They handled me so soft and kind, it was like getting the boost recently (so smooth that I even asked the nurse if she really boosted me).
MP: I am glad you feel that way. I will come soon to check you out. Stretch will join me w Corgi to make sure all is well with you.
O-arm: Thank you, doc, I am so happy, I am taken care and checked by the best. That is why I feel to give all to our best surgeons.
