    The study was a multicentre, observational, cross-sectional, open and monitored trial involving females who were subject to an examination using liquid crystal contact thermography device as a complementary tool to standard diagnostic imaging procedures of the breast glands. Dynamic angiothermography (DATG) is a technique for the diagnosis of breast technique, though springing from the thermography of old conception, is based on a completely different principle. DATG records the temperature variations linked to the vascular changes in the breast due to presence, change, and growth of tumors and lesions in breast .

This new and greatly revised edition of Professor Chandrasekhar's classic book Liquid Crystals () presents a systematic and self-contained treatment of the physics of the different types of thermotropic liquid crystals--the three classical types, nematic, cholosteric and smectic, composed of rod-shaped molecules, and the newly discovered discotic type composed Liquid crystal thermography book disc /5(2).

This is a new and greatly revised edition of Professor Chandrasekhar's classic book Liquid Crystals, first published in The subject of liquid crystals has grown into an exciting interdisciplinary research field with important practical applications.

Liquid Crystal Liquid crystal thermography book Liquid Crystal Types-• Encapsulated — the liquid crystal material is encapsulated Liquid crystal thermography book a 5 micron sphere suspended in a water based binder material-- provides excellent protection.

The book deals with lock-in thermography as a special variant of the well known IR thermography for all applications where the heat of the sample can be pulsed. Compared to steady-state thermography, the lock-in mode enables a much improved signal/noise ratio (up to x) by signal averaging, a far better lateral resolution, and it may provide.
