To curb illegal sex determination tests and control the skewed sex ratio, authorities here will use an active tracker technology for keeping sonographic machines under check.

Adopting the technology used in Kolhapur district in Maharashtra, authorities here have put sonography machines in ultrasound centres on the active tracker advanced technology equipment.

The active tracker would not only keep a record of the ultrasound machines but also connect them online with a central monitoring system and the keep check on pre-natal sex determination tests in the district.

Jhajjar deputy commissioner Ajit Balaji Joshi on Tuesday said the tracker would be supportive in curbing the misuse of ultrasound machines through its round-the-clock tab on them.

The technology developed by Magnum Opus Company, records sonography images and links it to an online portal called www.merigudia.com.

The data stored online could be used as evidence in suspicious cases of sex-selective abortions and the data is accessible only to doctors and a few government and company officials.

Joshi said the tracker was foolproof and once fitted could not be detached from the machines.

"The device will also be helpful in keeping an eye on all pregnant women who try to abort outside the district. A watch will be kept through the data available with the birth-death registration department and Anganwari and ASHA workers. For this, mobile phone equipped with GPS service will be provided to the workers," he said.

He informed that Jhajjar is the first district to adopt such technology in the state after the latest census showed 774 females against 1,000 males in the 0-6 age group.
