Study Notes

X-Ray Filtration and Patient Safety

Filtration in x-ray tubes blocks low-energy rays to protect patients from unnecessary exposure.
Medical x-ray tubes require a minimum aluminum equivalent filtration of 2.5 mm.

Dosimetry and Radiation Protection

Optical Stimulable Luminescent Dosimeter (OSL) uses aluminum oxide for measuring radiation exposure.
The annual effective dose limit for a radiographer is set at 50 millisieverts (mSv).

X-Ray Beam Quality

Increasing the half value layer (HVL) enhances the quality of the x-ray beam.

Lung Anatomy

The lung's base rests on the diaphragm, while the apex extends above the clavicle.

Patient Rights Under AHA Partnership

Patients are entitled to high-quality care, a safe environment, privacy protection, and assistance with billing.
They should also be informed about students conducting exams and the risks and benefits of treatments.

Radiographic Equipment and Errors

Off-focused error occurs when the source to image distance (SID) used is not compatible with the grid design (e.g., 42 inches instead of a recommended 50-72 inches).

Emergency Medications

Lasix is used for treating pulmonary edema when conservative treatments fail.
Benadryl is used for allergic reactions and hives.
Atropine is administered for hypotension and bradycardia.
Epinephrine is indicated for severe hypotension with tachycardia and other severe allergic reactions.

Infection Transmission

Infection requires a pathogen, a favorable environment for growth, and methods of transmission either exogenous or endogenous.

Protective Barriers in Radiology

Protective walls classified as secondary barriers must have a lead thickness of 0.8 mm and stand 2.1 meters (7 feet) high to block leakage and scatter radiation.
Lead is the most effective material for protective barriers due to its high atomic number.

Radiographic Procedures

The central ray (CR) for an erect AP abdomen projection is positioned at the mid-sagittal plane, 2 inches above the iliac crest.
The lateral projection is optimal for visualizing the zygapophyseal joints of the cervical spine.

Informed consent requires the patient to be mentally competent, of legal age, voluntarily consenting, and adequately informed about the procedure.

Communication Skills in Radiology

Paralanguage refers to the vocal aspects of communication, including speech tone and volume, which can enhance interaction quality with patients.
Clear, distinct speech is crucial for giving effective instructions for patient positioning.

Privacy Violations

Leaving patient billing statements exposed constitutes a violation of HIPAA regulations.

Imaging Technology

The phosphor layer of the computed radiography (CR) imaging plate captures and stores x-ray photons that pass through the patient.
