The ultimate ultrasound PAUT/TFM imaging machine

M2M Panther™ combines the speed required for industrial integrated Phased Array Ultrasound (PAUT) solutions, with the most complete set of Total Focusing Method (TFM) imaging techniques, making it the ultimate tool for R&D and procedure qualification.


The Ultimate PAUT/TFM Imaging Machine

M2M Panther™ is a phased array equipment designed for both desktop and industrial applications, offering unparalleled performance in a compact unit. Combined with its operating software Acquire, Panther is today the fastest and most versatile PAUT/TFM offering of the market.

Answering to Highest Expectations

To reduce cycle time and increase production capabilities, Panther has been designed with tremendous processing power and the highest data transfer rate (320 MB/s) of the market between the instrumentation and the monitoring computer.

Compact, Rugged & Scalable

Panther is compact (300 × 220 × 155 mm/11.8 × 8.7 × 6.1 in), IP54 and takes advantage of its parallel and stackable architecture (up to 16 units of 128 channels) to meet the speed and resolution requirements of the most demanding applications.

What You See, Is What It Is

Recognized amongst the highest resolution ultrasound techniques, Total Focusing Method (TFM) is natively implemented on Panther. With TFM pictures of 1.5+ million pixels in real-time, TFM offers efficient high-definition imaging for better flaw detection and easier defect characterization.

Advanced Phased Array Modes

Acquire is M2M’s up-to-date acquisition software dedicated to advanced PAUT, TFM settings and imaging. Acquire software has been designed for both industrial applications and laboratory demonstration.

Advanced Analysis

Acquire’s inspection data files are fully compatible with both CIVA and ULTIS analysis software.

The add-on extends standards Acquire views (A-B-S-D-C-scans + Top, Side, Front views cumulated, TFM & 3D views) to 3D merging of data, automatic analysis, and advanced reporting. In addition to real-time TFM imaging, full waveform FMC data acquired by Panther can also be post-processed by CIVA analysis add-on.

Software Development Kit (SDK)

In addition to the Acquire acquisition software, M2M offers a Software Development Kit (SDK) to customize application-based software interface for a fully automated inspection solution:

  • Full control in real-time of the Acquire software (remote server) : Gain, TCG, gates, alarms, coders, etc.
  • Real-time data retrieval (data server)
  • Software language independent
  • Very limited hardware knowledge: same program for all M2M hardware’s architectures

How to simplify welds NDT inspection using Total Focusing Method (TFM) and Phased Array UT (PAUT)

Girth-weld inspections require numerous parameters to be specified on most flaw detectors. The Gekko and its user interface (Capture) solve these challenges. Using off-the-shelf probes, the NDT inspector can quickly configure his unit, scan and analyze the collected data with confidence.

In this Webinar, you’ll learn:
How fast Capture makes it easy to get ready to scan using ultrasonic techniques such as Total Focusing Methods (TFM) and Phased Array (PAUT), how streamlined is the analysis of TFM data and how chosen approaches compare.
How adding TFM to a PAUT unit overcome limitations of each technique
A case study: girth-weld inspection setup, data acquisition, and analysis overview
