VKJ-BK7555 Backscatter X-Ray Inspection System for Large Baggage
The VKJ-BK7555 runs backscatter and transmission imaging together through a 755 x 555 mm tunnel. Transmission gives the penetration view of dense contents; backscatter is what makes organic and low-Z material stand out, which transmission-only systems tend to under-represent. Between them an operator assesses a large parcel without opening it.
Key benefits
- Backscatter and transmission imaging in one pass on the same item
- 755 x 555 mm tunnel takes oversized luggage and bulk parcels
- Backscatter highlights organic and low-Z contents
- Multi-energy colour classification by effective atomic number
- 30 to 38 mm steel penetration at 40 AWG wire resolution
Problems it solves
- Transmission-only imaging under-represents organic and low-density material
- Oversized parcels exceed the capacity of standard tunnel scanners
- Physical unpacking destroys package integrity and throughput
- Operators cannot separate material categories from a single grey image
Who it is for
- Operators screening items too large for a standard tunnel
- Sites where organic contents are the inspection concern
- Facilities that cannot afford to open packages to inspect them
Application scenarios
- Logistics centres and freight forwarding hubs
- Warehouse entrances and receiving docks
- Commercial transport and courier facilities
- Parcel handling and distribution centres
Technical features
- 17-inch HD LCD display
- Contrast adjustment, edge sharpening and real-time zoom
- Recorded scan playback with onboard archive
- Image storage for 100,000 images or more

Compared with other models in the range
The VKJ-BK6040E carries the same dual backscatter and transmission approach in a smaller 615 x 454 mm tunnel for parcels and hand-carried items. The BK7555 is the version for oversized baggage and bulk shipments that will not fit that opening.
Use guide
- Confirm the largest item clears the 755 x 555 mm tunnel
- Review transmission and backscatter views together rather than in isolation
- Use colour classification to separate organic from inorganic contents
- Apply edge sharpening and zoom before deciding to open an item
- Recall archived scans from the 100,000-image store when a review is requested

VKJ-BK7555 Backscatter X-Ray Inspection System for Large Baggage FAQ
Why add backscatter to a transmission scanner
Backscatter is highly sensitive to organic and low-Z material that transmission imaging alone may under-represent.
How large an item does it take
The tunnel is 755 x 555 mm.
How much steel does it penetrate
30 to 38 mm, at 140 to 160 kV tube voltage.
What resolution does it achieve
40 AWG wire resolution and 34 AWG penetration resolution.
Can scans be reviewed afterwards
Yes, with recorded playback and onboard storage of 100,000 images or more.
What display is fitted
A 17-inch HD LCD monitor.
