英文要約Title: SBIR technical innovation project / Research and Development on High-Performance examination of a tissue sample Check System for Pathological Examination Using RFID with antenna Fibers (FY2011-FY2012) FY2011 Annual Report

(1) Purpose of the operations:
Most pathological examination processes are carried out manually, which could lead to a higher incidence of incorrect data collation and subsequent misdiagnosis and inappropriate treatment. To prevent this kind of problem, we will develop information systems with RFID technology.

(2) Overview of the operations:
(i) An evaluation of the competitiveness of the RFID fiber system over the sample control system currently in use, a reading test using a pathology sample container bearing an RFID fiber and a prototype RFID-fiber reader, and an experiment to obtain basic data used for enhancing durability and operability.
(ii) Developing a prototype of the information systems.
(iii) Making a basic Business Plan for starting the business model.

(3) Results:
(i) The results for the goals a-f are:
a: When submerged in water, alcohol, formalin or paraffin, the RFID fiber was proven to be durable at the temperature and for the time required for paraffin embedding. In a boiling environment, the RFID fiber was proven to be durable at 100°C for up to 30 minutes.
b: A reading distance of several tens of mm or more was achieved. The experiment demonstrated that the reading distance can be controlled by adjusting the reader transmit power level.
c: A comparative experiment with a bar-code system was conducted and it was demonstrated that the reading accuracy is equivalent to or higher than that achieved by the bar-code system.
d: By placing the reader antenna 22 cm or farther away from other diagnostic equipment, as specified in the guidelines of the Ministry of Internal Affairs and Communications,
it was demonstrated that the system does not to interfere with other medical diagnostic equipment installed in hospitals.
e: Although the reading distance is reduced when paraffin is on the RFID fiber, it was demonstrated that the fiber is still readable. It was indicated that the reading distance can be controlled by increasing the reader transmit power level.
f: With a chemical charged in the sample container, the reading distance was reduced.
It was demonstrated that the required reading distance can be achieved by increasing the reader transmit power level. In addition, it was also demonstrated that the reading of the RFID fiber is unnecessary when cassettes are processed by fixation using an automatic machine.
(ii) A prototype of the pathology-sample traceability information system, that stores
the RFID fiber data in the database and allows whoever needs the sample data to easily retrieve the data whenever and wherever needed, was built, and its security was discussed.
(iii) In preparing for commercialization, outside contractors were reviewed and selected, commercialization was discussed with them, a cooperative partnership with them was established, and a business model draft was prepared. The details will be discussed with Matsunami-Glass and Sumitomo Shoji-Machinex.
