Medical Imaging Equipment List by Modality
Use this list to scope which modalities a facility needs. The right configuration (detector size, slice count, field strength, probe set) depends on the examinations you plan, patient volume and budget, so confirm it with your radiologist before you ask for quotes. Browse everything in imaging equipment and radiology.

Main Components and Parts of Medical Imaging Equipment
Quotes for imaging equipment are easier to compare when you know the main parts of each system. List every component in the quotation by model, and note which parts are wear items (X-ray and CT tubes, ultrasound probes, MRI cold heads) that will need replacement or service over the life of the system.
| Modality | Main components and parts |
|---|---|
| X-ray / radiography | High-voltage generator, X-ray tube (cathode and rotating anode), collimator, detector (DR flat panel or CR plates), anti-scatter grid and Bucky, patient table and wall stand, operator console with automatic exposure control (AEC). |

| Consumables and accessories | Ultrasound gel and probe covers, thermal printer paper, film or printing media, injector syringes, positioning pads, lead aprons and thyroid shields. |
Imaging Equipment by Facility Type
Most facilities start with X-ray and ultrasound and add CT or MRI as patient volume grows. These are typical starting lists. Your radiologist and the services you plan should decide the final list.
| Facility | Typical imaging equipment |
|---|---|
| X-ray clinic | Digital X-ray (DR) or CR system, wall stand and table, lead-lined room, lead aprons and thyroid shields, personnel dosimeters (TLD badges), viewing workstation, printer. |
| Ultrasound or sonography clinic | Colour Doppler ultrasound with convex, linear and endocavity probes, examination couch, gel warmer, printer, reporting workstation. |
| Diagnostic imaging centre | Digital X-ray, colour Doppler ultrasound, CT scanner, MRI (if planned), mammography and DEXA (optional), contrast injector, PACS and RIS, emergency drug and resuscitation kit for contrast reactions, UPS and generator backup. |
| Hospital radiology department | Fixed DR rooms, mobile X-ray for wards and ICU, C-arm for the OT, fluoroscopy, ultrasound, CT, MRI, mammography, PACS integrated with the hospital information system. |
| Operation theatre and cath lab | C-arm (or a fixed angiography system in the cath lab), radiolucent OT table, lead protection for staff. See the [OT equipment list](/guides/operation-theatre-equipment-list) and [cardiology equipment list](/guides/cardiology-equipment-list). |
| ICU and emergency | Mobile X-ray and portable or point-of-care ultrasound. See the [ICU equipment list](/guides/icu-critical-care-equipment-list). |
MRI Equipment List: What an MRI Suite Needs
An MRI suite needs more than the scanner. Anything that goes into the magnet room must be MR-safe or MR-conditional, because the magnetic field stays on even when the scanner is not scanning. Browse MRI machines.
| Item | Why it is needed |
|---|---|
| MRI scanner (1.5T or 3T) | 1.5T is the common general-purpose choice. 3T gives higher detail for neuro, musculoskeletal and research work. Lower-field and open systems suit claustrophobic or bariatric patients. |
| RF-shielded room (Faraday cage) | Keeps outside radio signals out of the images. Doors, windows and service penetrations must keep the shield intact. |
| Chiller, cold head compressor and quench pipe | Keep a superconducting magnet cold and vent helium safely outside if the magnet quenches. |
| MR-conditional patient monitor | Monitors ECG, SpO2 and blood pressure for sedated or unstable patients inside the scan room. |
| MR-conditional contrast injector | Delivers gadolinium contrast for contrast-enhanced scans. |
| Ferromagnetic detector and screening area | Catches metal objects before patients and staff enter the magnet room. |
| MR-conditional wheelchair, stretcher and oxygen cylinder | Ordinary steel equipment can be pulled into the magnet and cause serious injury. |
| Hearing protection, positioning pads and RF coils | Patient comfort and image quality for each body part scanned. |
| UPS or voltage stabiliser and HVAC | Protect the console and electronics, and keep the scan room and equipment room within the manufacturer's temperature and humidity limits. |
Room Readiness, Radiation Safety and Approvals
There is no universal room size or shielding thickness. Room layout, shielding, power, cooling and floor loading depend on the exact model, workload and site, so ask the manufacturer for its site-planning guide and have qualified professionals review the room before you order.
- X-ray, CT, C-arm, mammography and dental X-ray: shield the room for the equipment and workload, and provide lead aprons, thyroid shields and personnel dosimeters. In India, use only equipment type-approved by AERB and obtain the AERB registration or licence through its eLORA portal before use. See AERB guidance for diagnostic radiology.
- Ultrasound: in India, any facility with an ultrasound machine must be registered under the PC-PNDT Act, and suppliers may sell only to registered facilities. Keep the registration certificate ready when you buy.
- MRI: MRI uses no ionising radiation, but it needs RF shielding, magnet safety zoning, screening and quench venting planned with the manufacturer.
- Outside India: confirm the radiation-protection regulator, device registration and site-approval rules for your country before ordering. Country pages such as medical equipment in Nepal cover import basics.
What to Confirm in an Imaging Equipment Quotation
- Exact configuration: generator power, detector size, slice count, field strength, probes or coils, software packages and licences.
- What is included: console, workstation, table or stand, injector, UPS, PACS licences and any accessories quoted separately.
- Site works: who handles shielding, RF cage, electrical, cooling, flooring and transport into the room.
- Installation and approvals: installation, calibration, acceptance and quality-assurance tests, and the documents the regulator needs.
- Service: warranty period, preventive maintenance, uptime commitment, service-engineer location and response time, and the price and availability of tubes, probes and other wear parts.
- Refurbished systems: ask for the system's age, tube or cold-head history, software version and whether the manufacturer will still service it.

Frequently Asked Questions
Medical imaging uses X-ray machines (fixed, mobile and dental), fluoroscopy and C-arms, ultrasound machines, CT scanners, MRI scanners, mammography systems, bone densitometers (DEXA) and nuclear medicine scanners such as PET-CT. Supporting equipment includes detectors, probes, coils, contrast injectors, PACS and reporting workstations, and radiation protection.
The main types are X-ray radiography, computed tomography (CT), magnetic resonance imaging (MRI), ultrasound and nuclear medicine (PET and SPECT). Fluoroscopy, mammography and DEXA are specialised forms of X-ray imaging.
Most centres start with a digital X-ray system and a colour Doppler ultrasound machine, then add CT, MRI, mammography or DEXA as volume grows. They also need PACS and reporting workstations, radiation protection, an emergency kit for contrast reactions, power backup and the regulatory approvals for each modality.
An X-ray machine has a high-voltage generator, an X-ray tube, a collimator that shapes the beam, a detector (DR flat panel or CR plate), an anti-scatter grid and Bucky, a patient table or wall stand, and an operator console.
CR uses image plates that are read by a separate reader, while DR uses an electronic flat panel detector that sends images directly to the console. DR is faster per patient; CR costs less when upgrading an existing analogue X-ray unit.
There is no universal specification. Requirements depend on the modality, exact model, workload, site layout and local rules. CT rooms need radiation shielding designed for the site. MRI rooms need RF shielding, magnet safety zoning, cooling and a quench pipe. Use the manufacturer's site-planning guide and a qualified site review.
X-ray based equipment, including CT, C-arm, mammography and dental X-ray, must be AERB type-approved and registered or licensed with AERB through eLORA before use. Facilities with ultrasound machines must be registered under the PC-PNDT Act. MRI does not need AERB approval but needs manufacturer site planning and local building and electrical approvals.
Images are exchanged in the DICOM format and stored in a PACS (picture archiving and communication system). A RIS (radiology information system) manages appointments and reports. Confirm interfaces, licences and network requirements with the supplier.
