Mobiles Flashcards
What are the 2 types of Of mobile machines?
Analogue
Digital
What are features of analogue mobile machine?
power
drive
Analogue - Battery or mains powered manual or motor asists drive mechanism
Main features of a digital mobile machine?
Wired detector
Wireless detector
What are essential features of mobile machines?
High quality image production
Shock resistant material
Manoeuvrability (tight spaces)
Small footprint/compact (tight spaces)
Lightweight (long distances)
Radiation protection
Infection control
How does battery power affect image quality?
It is essential the mobile machine has sufficient energy to take to complete a sufficient exposure to ensure good image quality
How is battery energy managed on mobile machines?
Battery monitor (Mains independent) – (It is essential that the battery is always charged)
ensures sufficient power is available for exposures; Mains power available when battery life insufficient to make exposure
What does APR stand for and how does it ensure it good image quality?
APR – add atomically program Radiography - preset exposure factors
ensures effective selection and reproducibility of exposure
Also allows for ALARA to be achieved
What are angle indicators and how do they help produce good image quality?
Angle indicators ensures correct angle is being used for positioning purposes which provides reproducibility
A tape measure is also used to ensure correct SID
How are mobile machines shock resistant?
They Are made of:
Shock resistant material
Antistatic wheels
Earth connection - which insures electrical safety during operation

What are the design features of mobile machines to ensure effective movement?
They are:
Lightweight – battery
Manual/motorised drive
Multi directional/pivoting wheels
 Wide base plate - Balance (ergonomically designed)
Reliable breaking
Storage hopper – transporting image plates and pads et cetera
Collisions detector – stops mobile x-ray unit
Durability – able to cope with hospital environment in and out of lifts, ramps and doorways
What radiation protection is used to ensure safety with mobile machines?
Keylock – IR(ME)R 2017
Exposure at long distance
– Either long cord (2 m)
– remote control (up to 10 m)
Emergency stop button – prevent further exposure in till overridden
DAP meter
Lead rubber court holder/hook
What are some other technical safety features on the Mobile machine?
Retracting charging cable
Hopper for images plates et cetera
What infection control should be considered with mobile machines?
Hygiene – MRSA, blood Etc.
easy to clean
Are there any danger areas not readily cleaned
Cleaning agent/disinfectant
Plastic covers for image play/detector
What are some different aspects of digital mobile machines?
Instant images – three seconds
Detector can be wireless
Slightly larger and heavier
Barcode reader
DICOM right (digital imaging and communications in medicine) compatible
Flat panel detector (FPD)
Why would mobile need to be used?
The biggest reason why a mobile would be needed is because the patient is unable to come down to the department:
This can be due to many reasons such as:
Suction
Pacing
Level of consciousness
Traction
Monitoring
Ventilated
