16
Q

is a diagnostic examination that involves the acquisition of physiologic images based on the detection of radiation from the emissions of positrons.

A

PET, Positron Emission Tomography

17
Q

Imaging plate we make use of? in CR

A

PSP-Photostimulable phosphors

18
Q

PSP- Photostimulable phosphors are made out of?

A

Barium Fluorohalide Bromide and iodine with europium activators

19
Q

The PSP converts the x ray photons to a latent image through what process? and it then goes to the computer/monitor in a ?

A

Photoelectric absorption, PAC system, Picture Archiving and communications system

20
Q

3 capture element of DR

A

Sodium Iodide, Cesium Iodide, Gadolinium oxysulfide

21
Q

the three sodium iodide, cesium iodide and gadolinium oxysulfide it converts your x ray to light but (——) doesn’t, it converts it directly to electric signals

A

Amorphous Selenium

22
Q

What is the three step process in digital radiography

A

Capture element, Coupling Element and Collection Element

23
Q

what are capture elements?

A

Cesium Iodide, Gadoliniuk Oxysulfide, Sodidium Iodide and Amorphous selenium

24
Q

Ang ginagawa neto ay trtransfer niya yung signal, yan ang kukuha ng captur element towards your collective element

A

Coupling

25
Q

What are your collection elements

A

Photodiodes, Charged coupled devices and tin film transistors

26
Q

CR and DR is better because it eliminates the over exposure or under exposure of your films, mababa din ang radiation dose

Ang wala sa CR and DR na meron sa analog is the cassette doesn’t use barium, no more processing, the CR and DR is more advanced and the quality of image is greater

A

just get it okay, read it

27
Q

pano na chchange ang like basta something sa contrast media

A

because of atomic number, radiopaque materials such as barium can be traced and injected in the blood vessels

28
Q

what do we use in CR, still image
and what do we use in fluoroscopy

A

Image receptor, fluoroscopy

29
Q

when was DSA introduced? what was the technique used to make the development of DSA possible?

A

1970’s, Seldinger technique
