Diploma in X-Ray Technology (D-XRAY / DXRT) is a specialized 2-year undergraduate paramedical program designed to train technicians in medical radiography, diagnostic imaging physics, anatomical positioning, and radiation safety protocols.
1. Academic & Admission Framework
- Program Level: Undergraduate Paramedical Diploma
- Duration: 2 Academic Years (plus a mandatory 3 to 6-month clinical rotation/internship in a multi-specialty hospital)
- Eligibility Criteria:
- Completion of 10+2 (Higher Secondary) with Physics, Chemistry, and Biology (PCB) or Mathematics (PCM).

- Patient Care & Medical Ethics: Vital sign assessment, sterile techniques, infection control, handling emergency/trauma patients, medico-legal ethics, and basic life support (BLS).
Second Year: Radiographic Procedures & Radiation Safety
- Routine Radiographic Positioning:
- Thorax & Abdomen: PA/AP erect chest, lateral decubitus, plain abdominal views (KUB, erect).
- Extremities: AP, lateral, and oblique projections of hands, wrists, forearms, elbows, shoulders, feet, ankles, knees, and hips.
- Spine & Pelvis: Cervical (open-mouth, flexion/extension), thoracic, lumbar (AP/Lat/Oblique), sacrum, and coccyx.
- Cranium & Facial Bones: Skull AP/Lat, Townes view, Waters view for paranasal sinuses (PNS), submentovertex, and mandible.
- Special Radiographic Procedures & Contrast Media:
- Radiographic contrast agents (positive iodinated and negative agents), adverse reaction management.
- Barium swallow, Barium meal, Barium follow-through (BMFT), Barium enema, Intravenous Urography (IVU), Micturating Cystourethrography (MCU), Hysterosalpingography (HSG), and Sialography.
- Radiation Protection & Dosimetry:
- Biological effects of ionizing radiation (stochastic vs. deterministic).
- ALARA principle (As Low As Reasonably Achievable).
- Cardinal rules: Time, Distance (Inverse Square Law: I ∝1/d²), and Shielding.
- Structural barrier thickness (minimum 1.5 mm to 2.0 mm lead equivalent), personal protective equipment (PPE: 0.5 mm lead aprons, thyroid collars, gonadal shields).
- Personnel monitoring devices: Thermoluminescent Dosimeters (CaSO4:Dy) TLD badges) and Optically Stimulated Luminescence (OSL) badges.
- Quality Assurance & Maintenance: Collimator light-beam alignment, perpendicularity checks, darkroom fog testing, grid alignment, and routine equipment calibration.
3. Clinical & Technical Competencies Acquired
- Operating fixed, ceiling-suspended, floor-mounted, and high-frequency X-ray units.
- Managing mobile (bedside) X-ray units in Intensive Care Units (ICU), Neonatal ICUs (NICU), and Operation Theatres (OT).
- Operating C-arm fluoroscopy units during orthopedic reductions, foreign body retrievals, and urological interventions.
- Optimizing technical exposure factors (kVp, mAs, SID/FFD) to ensure high diagnostic yield while minimizing patient dose.
- Handling Digital Imaging and Communications in Medicine (DICOM) workflows and Picture Archiving and Communication Systems (PACS).
4. Career Opportunities & Job Profiles
- Diagnostic X-Ray Technician: Government and private hospitals, community health centers, and emergency trauma setups.
- Mobile / Bedside Radiographer: In-patient wards, ICUs, and home-care diagnostic service providers.
- Clinic / Diagnostic Center Technician: Multi-specialty diagnostic imaging chains, pathology-radiology labs, and polyclinics.
- Radiology Assistant: Working alongside senior radiographers and radiologists during fluoroscopic and non-vascular interventional procedures.
- Medical Equipment Application & Support Assistant: Basic equipment maintenance, darkroom chemical distribution, and diagnostic supplies management.
5. Academic Progression Pathway
- Lateral Entry to BMRIT / B.Sc. RIT: Diploma holders are eligible for direct 2nd-year admission into Bachelor of Medical Radiology and Imaging Technology degree courses.
- Post-Diploma Certifications: Specialized certificate courses in Computed Tomography (CT), Mammography, or Bone Densitometry (DEXA).
- Long-Term Trajectory: B.Sc. RIT → M.Sc. RIT / MMRIT → Specialization in Cross-Sectional Imaging (CT/MRI), Research, or Academic Faculty roles.
