FAQ

RPV operates two custom-made X-ray CT scanners manufactured by Toshiba IT Control Systems, Inc.
Their main specifications are as follows:

(1) Microfocus X-ray CT Scanner (230 kV)
TOSCANER-32300μFD (RPV Custom Model)

• 16-inch flat panel detector (FPD), custom-ordered
• Spatial resolution: 5 μm (matrix size: 1024 pixels)
• Scannable size: Ø500 × H700 mm
• Maximum sample weight: 20 kg

• Ideal for extracting fine defects and scanning detailed internal structures
• Capable of scanning relatively large samples
• Suitable for materials such as rubber, resin, and small-to-medium components

(2) High-Power Industrial X-ray CT Scanner (450 kV)
TOSCANER-24500twin FD (RPV Custom Model)

• Equipped with both a line sensor and a 16-inch FPD
• Line sensor resolution: 200 μm
• FPD resolution: 200 μm
• Scannable size: Ø600 × H800 mm
• Maximum sample weight: 100 kg

• Suitable for scanning metal parts and large components
• Can penetrate samples that the 230 kV micro-CT cannot
• Ideal for reverse engineering and detailed 3D data acquisition

(1) Creating 3D models that faithfully reproduce internal structures

• Useful for CAE (computer simulation)
• High-definition 3D models of internal structures and defects
• 3D models can be exported for 3D printing and defect analysis

(2) Visualizing internal defects in an easy-to-understand 3D format

• 3D animations and detailed reports allow users to quickly identify defect location and distribution

(3) When in-house CT equipment is busy or overbooked

• For internal quality inspections, data is typically delivered within 3 business days after receiving samples
• Reverse engineering: approx. 5 business days for STL, 4 weeks for CAD conversion

(4) When in-house resources do not allow time for analysis

• We also accept requests for analysis only, 3D modeling only, or CAD conversion only

(5) Evaluating CT capabilities before purchasing a system

• We can provide reference data that matches the specifications and performance of the CT system you are considering

(6) Other use cases (e.g., patent or product validation)

• Investigating whether a competitor’s product infringes a patent
• Analyzing product-related claims from business partners

After detailed consultation, we prepare clear and objective data.

Please send us as much information as possible about the sample you wish to scan, including dimensions, material, and a photograph of the sample. RPV will respond to you as soon as we receive the information, and in some cases we will perform a free trial scan if the scan is too delicate or if we need to match your image with ours. After reviewing the data, you may decide whether to commission the service or not.

Materials that are easily penetrable by X-rays are good at X-rays, while materials that are difficult to penetrate are poor at X-rays.

(1) Materials we specialize in: rubber, resin, aluminum, etc.

(2) Materials that are difficult to work with: lead, iron, copper, titanium, etc. (possible if the X-ray transmission distance is within 30 mm)
Please consult with us if the X-ray penetrates iron, copper, etc., which are difficult for X-rays to penetrate (distance to allow X-rays to penetrate is 30 mm or more).
It may also be possible to scan a combination of the above different materials, such as resin and steel, and it may be possible to separate the data into segments.

(1) 230kv micro CT
Scanning area: φ500mm, H=700mm (H=approx. 900mm for vertical composite)

(2) 450KV high output CT
Scanning area: φ600mm, H=600mm (H=approx. 900mm for vertical composite)

Accuracy depends on the resolution of the x-ray CT scanner and the size of the specimen to be scanned.
The resolution of our X-ray CT scanner is as follows

(1) Micro CT Scanner (230KV)
FPD: Spatial resolution: 5μm (Matrix size = 1024 pixels)

As a rough guide, for example, the theoretical accuracy of a sample 20 cm in size when scanned with a 230 KV micro CT is 200 mm ÷ 1024 ≈ 0.2 mm/1 pixel.

(2) Industrial CT Scanner (450KV) High Power CT
Line sensor: Spatial resolution: 200μm
FPD: Spatial resolution: 200μm

1. create 3D data (STL format) that reproduces the internal structure
1) Reverse engineering of automotive parts (3D modeling for CAE)
(2) Shape comparison in 3D with CAD design drawing
(3) Creation of data for modeling with a 3D printer

2. identify defects (caves, cracks, etc.) in three dimensions
(1) Internal quality evaluation of aluminum die castings, etc.
(2) Observation of defect extraction and weld penetration in the welding area

All cross-sectional images in X, Y, and Z directions
Video (RPV edited)
Analysis report (defect extraction and volume, etc.)
STL data (conversion from CT data only)

For details, please refer to the “Services” page and the “Sample Download of Deliverable Data” page.
STL data → CAD conversion will incur additional costs.

Please use STL or IGES or STEP format.
We will return your data as soon as the work is completed and will not keep it in the company.

If you have CT data, we can provide only 3D defect analysis and 3D modeling. Of course, we can also handle CAD conversion only.

Our technical sales staff regularly visit the Kanto and Kansai areas, We can arrange a meeting at your desired date and time.
The frequency of visits is about twice/month in both the Kanto and Kansai areas.

We can also arrange for you to come to our office for on-site analysis and data preparation.
Since CT scans require a certain amount of time, please send us your specimens in advance so that we do not have to wait for you at the time of the visit.

A scanned 3D model contains the tolerances of the product. In addition, errors occur when converting the data, so they are not suitable as blueprints for the purpose of manufacturing products. If they are to be used as blueprints, they need to be corrected or modified by a professional engineer.

We are sorry, but we do not support rental of CT equipment.
