Profile: 4-D Neuroimaging (FDNU.PK)

4-D Neuroimaging is a provider of medical imaging systems. The Company is engaged in the development, marketing and sale of medical instrumentation that helps the physicians to monitor the body functioning and also offers a vital tool to neuroscientists, that helps them to unravel the brain functions. The company’s first magnetoencephalography (MEG systems) were single channel systems with second order gradiometer detector coils. They can be operated in an unshielded environment. The products of the Company include MEG systems, Stimulus Systems, Custom Products and MAGNES Software.

The MEG systems of the Company measure and locate magnetic fields produced by the human body, and help in the non-invasive diagnosis of a range of medical disorders. With the help of these measurements, the MEG systems provide useful information about the normal and abnormal functioning of the brain, heart, spine and other organs. MEG is a non-invasive neurophsiological technique that measures the magnetic fields generated by neuronal activity of the brain.

Stimulation devices used in the non-magnetic environment are essential for MEG. These stimulation devices are required for the basic research and routine clinical applications of MEG for presurgical functional mapping and epilepsy surgery evaluation. The company provides a collection of effective stimulus hardware and software systems for visual, auditory, and somatosensory stimulation. These stimulus devices are non-magnetic and hence do not interfere with the extremely sensitive magnetic measurements of MEG. These stimulus delivery systems are used with various computer generation and delivery programs of research and clinical protocols. The company is also engaged in the development of custom biomagnetometer systems, such as the ferritometer, the CryoSQUID, the MicroSQUID, and custom cardiac and fetal systems. The company also started working on a Primate System.

The STA/R software package of the Company was co-developed with ETIAM, a software firm merged with the University of Rennes, France. The company’s STA/R offers an interactive interface linking the 4-D MEG signal and MEG source modeling with an anatomical reference, which is a MRI that allows users to effectively visualize their data. The Boolean Averager/Artifact Detection package was developed specifically for use involving studies of cognitive activity.
