Unfors Instruments AB (UI) designs and develops instruments for measurements of X-ray in clinical environments. The main use for the instruments is in design, production and calibration of medical X-ray equipment and related products. Customers are manufactures of X-ray equipment, hospitals and private clinics
Sales are spread out in 30 countries world-wide. Approximately 1/3 each of the products are sold in Europe, North America and Asia respectively. UI was founded in 1993. The annual turnover is today (1998) 1000 kECU and the number of employees is 5.
The overall ambition with this AE is to minimise the X-ray exposure to the human population without losing the high quality of the produced image. The products must also be very easy to use and easy to learn.
The objective of the application experiment was to integrate the measurement of dose, dose rate, exposure time and peak energy into a single detector unit to develop one multi-parameter instrument. The advantage with a multi-parameter instrument is that you are able to measure several parameters in a single reading.
Before the Application Experiment UI did not have any multi-parameter instruments on the market but they did have 20% of the market for single-parameter instruments. Single-parameter instruments are based on standard silicon detectors, discrete analogue components and micro controller.
The experiment lasted from 1st of December 1996 until 30th of October 1997. This was according to the original plan and the contribution from the CEC was 103 kECU. Prototypes have successfully been manufactured and evaluated. The multi-parameter instrument is now in production. The payback time for the project was reached before the end of 1997 in the time frame of six months. The return on the FUSE investment will be 16 fold within a period of five years.
UI has, during the project, learnt a lot from this AE: How to deal with an electronic complex design, both including conventional electronics, microsystem technologies and software. How to measure extremely low currents accurately. How to design EMC robust electronics for harsh environments with protected housings in plastic.

Detailed information

You can also benefit from microelectronics

Microsystem technology provided Unfors Instruments AB with the means of improving its products and enhancing its market position. You can also achieve significant benefits by acquiring the right microelectronics technology and utilising it in your product or manufacturing process. You can get help from FUSE to realise this.

FUSE is a technology transfer programme, funded by the European Commission to stimulate the wider use of microelectronics technologies by European enterprises to increase their competitiveness and enhance their economic growth. The demonstrator described here is one of many examples in the public FUSE portfolio covering the whole spectrum of microelectronics technologies and spanning a wide range of applications and industry sectors.

FUSE provides you with:

  • Best practice in acquiring specific microelectronics technologies and conducting full development projects through the FUSE portfolio of real life demonstrator documents.
  • Local training and expert support to plan your innovation realistically and help you conduct your project successfully.
