  1. Geometry
  2. Film
  3. Distance
  4. Screen
  5. Focal spot size
  6. Motion
23
Q

Controlling factors of OID and SID

A

Magnification

24
Q

Observe proper XRT distance with IR/ body part

A

Magnification

25
Q

How far the bofy part is from the image receptor

A

Object-to-image raceptor distance (OID)

26
Q

How far the XRT is from the IR

A

Subject-to-image receptor distance (SID)

27
Q

Deviation from true sahpe

A

Shape Distortion

28
Q

The shape distortion of the body part must be analyzed and the primary controlling factors must be studied

A
  1. Alignment of body part
  2. Central ray direction
  3. Anatomic part
  4. IR placement
  5. Angulation of XRT
29
Q

Discuss Display of Radiograph

A

Should be mounted in a view box/ illuminator/ negatoscope for proper viewing following the normal orientation of the body or normal anatomic position to identify properly the location of the pathologic condition

30
Q

A narrative or reward of past events and cicumstances that are or may be relevant to patient’s current state of health

A

Clinical history

31
Q

An account of past disease, injuries, treatments, and other strictly medical facts of patient

A

Clinical history

32
Q

RT should determine history of patient for precautionary measures especially for (1), (2) and also to determine patient’s (3)

A
  1. contagious diseases
  2. area of interest to be managed
  3. current condition
33
Q

Discuss Diagnosis and the Responsibility of the RT

A

RTs are not allowed to divulge any info regarding patient’s condition and diagnosis. Only doctors are allowed to inform a patient regarding his/ her condition

34
Q

Discuss Care of Radiographic Examining Room

A
  1. It should be cleaned and disinfected including equipment (XR machine), radiographc accessories like CXTs, caliper, markers, etc. to avoid reansfer of contagious disease from one patient to another
  2. Should be prepared before the arrival of patient
  3. Linens and pillows should arrange properly and always neat and clean
