RRB Paramedical Radiographer Syllabus

The RRB Paramedical exam for the post of Radiographer (X-Ray Technician) is a single-stage CBT of 100 marks in 90 minutes. The 70-mark Professional Ability section is based on your DMRIT or B.Sc Radiology/Radiography curriculum. Radiography is a technical and precision-based field, and questions test both theoretical knowledge and practical understanding of imaging procedures.

Professional Ability Syllabus for Radiographer (70 Marks)

Radiographic Physics and X-Ray Production

Covers the principles of X-ray production: construction and working of the X-ray tube, types of radiation (primary, secondary, scatter), properties of X-rays, the electromagnetic spectrum, factors affecting radiographic image quality (kVp, mAs, SID, OID, focal spot size), and the photoelectric effect and Compton scattering. Know how to select the correct exposure factors for different body parts.

Radiographic Anatomy and Positioning

This is the most practically important topic for a Radiographer. It covers standard radiographic projections for all body regions: chest, abdomen, skull, spine (cervical, thoracic, lumbar), upper limb, lower limb, and pelvis. Know the patient position, beam direction, central ray entry point, and image receptor placement for each standard projection. Know how to modify positioning for trauma cases.

Radiation Protection and Safety

Covers principles of ALARA (As Low As Reasonably Achievable), the three cardinal rules of radiation protection (time, distance, shielding), types of radiation monitoring devices (TLD badge, film badge, dosimeter), dose limits for occupationally exposed workers and the general public (AERB guidelines), and protective equipment (lead apron, thyroid shield, gonadal shield).

Radiographic Pathology

Covers the radiological appearances of common diseases that a Radiographer identifies while preparing images: pulmonary tuberculosis, pneumonia, pleural effusion, fractures, cardiomegaly, renal calculi, bowel obstruction, and spinal conditions. Knowledge of these pathologies helps the Radiographer assess image quality before sending to the Radiologist.

Contrast Media and Fluoroscopy

Covers types of contrast media (positive: barium sulphate, iodinated compounds; negative: air, CO2), their properties and uses, contraindications, reactions and their management, and contrast-based investigations: Barium Swallow, Barium Meal, Barium Enema, IVU (Intravenous Urography), HSG, and Myelography. Know the patient preparation required for each procedure.

Special Imaging Modalities

Covers the basic principles and clinical applications of advanced imaging: CT (computed tomography), MRI, Ultrasound, Nuclear Medicine (basic concepts), Mammography, and Dental Radiography. Know how each modality works physically (use of X-rays, magnetic fields, sound waves) and what conditions each is best used to diagnose. Detailed technical knowledge of CT and MRI scanners is not required at this level.

Film Processing and Digital Imaging

Covers conventional film processing (developer, fixer, wash, dry) and digital imaging systems including CR (Computed Radiography) using imaging plates, DR (Digital Radiography) with flat-panel detectors, PACS (Picture Archiving and Communication System), and DICOM standards. Know the advantages of digital over conventional imaging systems.

Patient Care in Radiology

Covers patient communication, positioning assistance for immobile patients, infection control in the radiology department, handling of contrast media reactions, management of emergency situations in the X-ray room, and patient consent procedures. Also covers radiation protection for pregnant patients and paediatric patients specifically.

Preparation Tips for Radiographer

•        Radiographic Positioning is your most important topic — revise every standard projection with its patient position, direction of beam, and image details.

•        Radiation protection principles and AERB dose limits are frequently tested in a regulatory context — know the exact dose values.

•        Learn the principle behind contrast media reactions and the emergency management steps, as these practical knowledge questions appear regularly.

•        Study from DMRIT/DMRT textbooks and positioning atlases (Clark's Positioning in Radiography) as the professional ability questions directly reflect that curriculum.

•        For special modalities (CT, MRI, USG), focus on the physical principle, main clinical uses, and contraindications rather than technical operation details.

Frequently Asked Questions (FAQs)

What is the eligibility for RRB Paramedical Radiographer?

DMRIT (Diploma in Medical Radiology and Imaging Technology) or equivalent qualification from a recognised institution, plus registration with the relevant authority.

Is knowledge of CT and MRI required for the Radiographer exam?

Basic principles and clinical applications of CT, MRI, and Ultrasound are expected. Detailed technical operation of these machines is not required at the entry-level Radiographer post.
