Gamma Camera Installation Timeline: Dependencies and Handover in Bangladesh
By Vvon Engineering Team | Published | Updated
Plan a gamma-camera project schedule around manufacture, room readiness, delivery, acceptance and authorisation. Assign responsibilities before setting an opening date.
A gamma-camera project schedule depends on configuration, manufacture, import and delivery, room readiness, specialist attendance and authorisation. Obtain the dependencies and responsible parties in writing before assigning an opening date. This guide is a scheduling checklist; use the separate room-readiness guide for structural, access and utility preparation.
The stages, and what each one waits for
Order confirmation and factory allocation. Depends on whether the configuration is a standard build or specified to order, and particularly on the collimator set, which is often the longest item in the box.
Shielding design and regulatory submission. Can start the day the order is placed and should. It needs the medical physicist and the final room drawing, not the finished room.
Civil and services works. Room construction, floor loading against the manufacturer's load plan, door and corridor dimensions, cable routes, dedicated air conditioning, clean power and earthing, and drainage if therapy is planned.
Shipping. Air against sea freight is a decision made at order stage, not later, and it is the one place a hospital can genuinely buy time with money.
Customs clearance and inland transport. Depends on document completeness far more than on volume, and demurrage accrues while a paper is corrected.
Delivery, route and rigging. The crate has to physically reach the room. This is confirmed with a tape measure, not on a drawing.
Installation and calibration by the manufacturer's engineer. Requires the power, earthing and air conditioning already proven on site, not promised for next week.
Acceptance testing and QA baselines, witnessed by the hospital's medical physicist and signed off.
Applications training and protocol build, using the studies the department will actually run.
Operating authorisation and the first radiopharmaceutical delivery, then the first patient.
What actually causes the delay
Site readiness, power, authorisation, tracer supply and manufacturer availability can all affect the programme. Responsibilities are shared between the institution, contractors, suppliers and authorities; the hospital does not control every delay.
The room is not finished. "Ready" means finished, clean, dry, air conditioned, powered and lockable. Walls up with the flooring still to come is not ready, and an engineer who flies in to find it is an engineer who flies out again and returns when there is a slot.
Power and earthing are not to specification. This is discovered on day one of installation and cannot be fixed in an afternoon. Have the supply, the stabiliser, the UPS and the earth measured and documented before the engineer travels.
Regulatory work started late. The shielding submission and the authorisation to hold radioactive material sit on a different clock from the equipment. Started at order, they cost nothing in elapsed time. Started at delivery, they are the whole delay.
The isotope supply was arranged last. A camera that is installed, accepted and authorised, with no technetium in the building, is not a working department. Departments do this more often than they admit.
Allow for local weather, access restrictions, holidays and supplier shutdowns using confirmed calendars and contingency. Their impact varies; a holiday does not stop all freight or clearance services in the same way.
How to compress it honestly
Almost all of the available compression comes from running things in parallel that hospitals tend to run in series.
Run compatible workstreams in parallel: manufacturer drawings, shielding review, regulatory planning, room works, staffing and procurement of genuinely required accessories. QA phantoms must match the acceptance plan; external patient-positioning lasers such as MAXX are not mandatory for every gamma camera. Coordinate source delivery with authorisation and readiness rather than a calendar date alone.
Then ask every party for their own lead time in writing, put the dates on one sheet, and see which one is genuinely last. The programme you can defend is the one where every date has a name against it.
