Study Notes

Mobile vs Portable

The key difference between 'mobile' and 'portable' is that mobile devices are vehicles that can move on their own, while portable devices are designed to be carried or moved.

Mobile Cases for Technologists

Mobile cases are most common for technologists during emergency situations, patient transport, or in areas where a fixed X-ray unit is not available.

Patient Problems during Mobile Exams

Patient problems that can be encountered during mobile exams include discomfort, anxiety, and claustrophobia, requiring technicians to be adaptable and empathetic.

Ideal Positioning for Mobile X-ray Exams

The ideal positioning for mobile X-ray exams involves aligning the X-ray beam with the body part being examined, ensuring proper patient positioning and minimal movement.

Mobile X-ray Unit Batteries

Mobile X-ray units use sealed lead acid batteries, which are reliable and require minimal maintenance.

Battery Charge Time and Driving Range

The maximum charge time for the battery in a mobile X-ray unit is typically 2-3 hours, with a driving range of around 100-150 miles.

X-ray Cassette and Side Marker

The side marker on the X-ray cassette contains a lead identifier with the patient's name and other identifying information.

Source-to-Image Distance (SID)

The required Source-to-Image Distance (SID) for accurate X-rays is typically 40-45 inches, ensuring optimal image quality.

Portable Marker in X-ray Imaging

The purpose of a portable marker in X-ray imaging is to identify the patient and provide additional information about the exam, such as the date and time.

Mobile X-ray Unit with Flat Plate Detector (FPD)

The detector size of a mobile X-ray unit with Flat Plate Detector (FPD) is typically 14x17 inches, with a weight of around 265 pounds.
The scintillator material used in the FPD is cesium iodide, which provides high-quality images with minimal radiation exposure.
The grayscale depth of the detector in a mobile X-ray unit with FPD is 14 bits, allowing for high-contrast images with detailed information.

Wireless Detector System

The purpose of the wireless detector system in a mobile X-ray unit is to enable easy and efficient image capture, with minimal cables and setup requirements.

Anatomical Programming

The purpose of anatomical programming in a mobile X-ray unit with FPD is to optimize the X-ray beam and technique for specific anatomical regions, ensuring accurate and high-quality images.
