Radio-Pharmaceuticals

Radiotracers are chemical compounds that are used to diagnose or deliver therapy to specific organs and tissues. The radiotracer consists of a linking molecule, a binding molecule and a radioactive compound. Radiotracer is injected into the body and it binds to specific target cells in the body. The linking molecule binds the radioactive compound to the binding molecule, which then binds to specific cells in body.

The radiotracer decays by emitting ionizing radiation that damages nuclear DNA, thereby stopping division of cells (cancer as well as normal cells). Radiotracers are not something new. In fact, they have been around for 100 years !!

Introduction to Proton Therapy

What is Proton therapy and why should you care?

Conventional Radiation therapy techniques use X-rays (‘photons’) to treat cancer by focussing X-rays on cancer regions. Proton therapy is a technique to treat cancer by the use of ‘protons’. The usage of protons to treat cancer may be advantages in various ways.

Radiation therapy for cancer treatment causes unnecessary exposure to healthy cells also, posing health risks on the patient. We can use Proton therapy for the following reasons.

  • We may want to expose children and pregnant women to lower amount of radiation.

Introduction to Theranostics

Introduction to Theranostics

Theranostics is a field of medicine that refers to a combination of diagnostic imaging and therapy to treat various types of cancers. Theranostics = Therapy + Diagnostics. Patients are imaged and depending on the tumour size and spread, are identified for therapy. The therapy is given by localized radiation delivered only to the diseased region, reducing the impact on surrounding healthy cells.

Principle of Theranostics

How does it work?

  • Radioactive compound is attached to a linking molecule that is bound to the binding molecule, which attaches to the cancer cell.

Brief History of Biometric System

In ancient times about 40,000 years ago, men and women who lived in caves of Indonesia are documented to have the oldest cave painting of hand stencils. Some believe the reasons was they were to communicate and their fingerprints ‘have acted as unforgettable signatures of the originator’.

Oldest known Hand Stencil

By 500BC the Babylonian and Egyptian merchants began to use fingerprints in clay tablets to settle business transactions. It was not until 1892 that a strong mathematical analysis of the index to uniquely classify fingerprint was developed.

Top 7 Innovations in Healthcare 2014

This year we’ve witnessed amazing innovations in technology with everything from wearable tech like Google Glass or Nike+ to the recent introduction of Coin, one card that stores all your credit cards, debit cards, personal accounts, business accounts and other cards typically filling your wallet. The healthcare industry was no exception to the rise in disruptive technology changing the way people are impacted. What are some of the most influential healthcare technologies you’ve seen appear this year?

Without a doubt the pace at which new technology is impacting our everyday lives is increasing at lightning speeds. As of today, 29% of Americans say their phone is the first thing and last thing they look at everyday which is a telling sign of how connected we are becoming to technology.

Non-magnetic micro connectors for MRI

Small, robust and extremely non-magnetic! These are the qualities of the new micro-D connectors developed by Axon’ Cable.  These miniature connectors are designed for devices, which rely on magnetism when operating.  This is the case, for example, for MRI scanners where the magnetic field generated must remain constant and stable to obtain reliable and high quality 3D images.

The non-magnetic connectors developed by Axon’ Cable have not only a very low residual magnetic field  (less than 1 nT – about 50,000 times lower than the earth’s magnetic field), but it is also almost impossible to magnetize them.  They cannot, therefore, interfere with the magnetic fields produced by the magnets of medical imaging devices or particle accelerators used by scientists.
