-in technologist
REM, Sievert Sr(SI)

19
Q

Absorbed dose unit-

A

-how much absorbed in patient
-rad, Gray (Gy) (SI)

20
Q

Task analysis form-

A

doing job right;judged on how you do job right

21
Q

legal Technologist Dose-

A

50 msv (5 rem) per year

22
Q

Image reader-

A

-laser converts x-ray photon energy into digital electronic signal to display on workstation.
-cassette erased by light for reuse

23
Q

Photostimulable Phosphor Plate(PSP)-

A

replaced film; energy from x-ray beam is trapped

24
Q

increase sensitivity if-

A

less specialized, rapidly divide, immature cells0

25
Directed Radiography (DR)-
-portable flat-panel detector (special bucky contains detector) - no reader needed; automatically displays on workplace monitor
26
Computed Radiography (CR)-
- uses specialized digital cassette requires processing in CR reader
27
Student dose-
1 mSv (.1 rem) per year
28
Fetal dose-
0.5 mSv (0.05) rem per month
29
Exposure Units-
roentgen (kg, Airkerma(SI)
30
Radiation units-
radiation from tube to technologsts
31
Genetic-
occurs in future offspring of exposed individuals
32
Clinical behavior form-
-ability to get along with others -time management -attitude
33
Decreased magnification= ____ spatial resolution
increased
34
Somatic- 2 types-
-Occurs in individual -short term; nausea vomiting, decreased blood count, seizures, death -long term; cancer, cataracts, life span shortening
35
Clinical uniforms-
-royal blue; conservative -pant and top same fabric -dress length no short than 2 inch below knee -black, white, gray, royal blue
36
All tardy time will have to be made up if it excess__ -____ will count toward tardy time -student who misses 3 days will____
- 1 hour -leaving early or being sent home - receive a warning (DAF)
37
Program goals- (4)
1. graduates will demonstrate clinical competence 2. students will develop effective communication skills 3. students will develop effective critical thinking and problem solving skills 4. Program will satisfy the communities need for qualified radiographers
38
If four days are missed students clinical grade will be- -each subsequent absence may result in__ pending__-
-dropped a letter grade -dropped letter grade; department review
39
If student fails to follow proper call in procedures-
grade will lower a letter for each day they fail to
40
Inclement weather policy-
safety first at all times! - if news say something don't have to call in! - text instructors to check 1st, cause not on same school
