Tpm's ultrasound system provides a means of non-invasive measurement of various skin-related pathologies: tumors, nevus, skin thickness, conditions related to skin dryness, collagen implants, preoperative thickness measurement of tumors in a non invasive manner, skin treatment checkup/follow-up.
The DUB is delivered as a complete system in a standard PC housing and includes the Ultrasound Applicator (also produced by tpm) based on a PCI interface and Windows OS. (Each applicator being specific to a particular frequency - namely 22, 30, 50, 75 and 100 MHz for the High Frequency Ultrasound System.)
Specifications are shown below:
Hardware
A/D-Board with 200 MHz sample rate
Bandwidth P/R 100 MHz
B-Scan applicator 22 MHz
Storage - 100000 Scans
15" TFT-Display
internal Modem/ISDN for maintenance
LAN10/100
CD-Writer
Software
Windows 2000 Professional
D4W - DUB for Windows
Patient oriented database
Tpm's fast A/D converter, enables up to 1 GHz sampling rate. The ultrasound applicator, which is controlled by a PCI controller board is programmed with a Jungo WinDriver-based driver, and a high quality Pulser/Receiver, generates and receives the pulses and signals. WinDriver enables the controlling and mechanical movement of a transducer meaning that control commands and switches send position information to the PC.
When tpm decided to provide a Windows series of PCI-based systems, their rationale for the move was to provide the following benefits to their customers:
- Print to any Windows-compatible printer
- Use individual printing templates
- Export to different graphic formats
- Copy to other applications via the clipboard
- Store scans automatically
- Work with scans more efficiently thanks to patient-oriented database
- Connect to the network easily
- Backup via Windows-compatible backup systems
- Use standard Windows interface
- Evaluate scans from multiple terminals
- Maintenance via Modem
DOS just didn't provide these benefits. However, tpm developers knew that the driver development for the Windows system would stall their time to market and therefore sought means to eliminate the bottleneck.
"Initially we tried to develop a driver in-house, however it was far too complicated and after 2-3 weeks of frustration, we quit and then searched for a tool to do the job. WinDriver enabled our engineer to get a basic driver up and running in a few minutes for the PCI card, and within a few hours we had a working driver for our system," said Sven Scharenberg tpm Chief Engineer. "The obvious benefits were its absolutely ease of use and very fast development time. Great software!"
