An introduction to medical imaging with coherent terahertz frequency radiation

Methods have recently been developed that make use of electromagnetic radiation at terahertz (THz) frequencies, the region of the spectrum between millimetre wavelengths and the infrared, for imaging purposes. Radiation at these wavelengths is non-ionizing and subject to far less Rayleigh scatter than visible or infrared wavelengths, making it suitable for medical applications. This paper introduces THz pulsed imaging and discusses its potential for in vivo medical applications in comparison with existing modalities

Non-pharmacological interventions for chronic cough:The past, present and future

Non-pharmacological interventions have been explored in people with refractory chronic cough. Normally delivered by Physiotherapists and or Speech and Language Therapists, these interventions aim to educate patients about their cough, provide them with cough suppression techniques and breathing exercises, improve vocal/laryngeal hydration and psychoeducational counselling to help them gain greater control of their cough. Six key studies have been completed over the past 12 years that have consistently found non-pharmacological interventions help to improve quality of life and reduce cough frequency. Some studies also found improvements in cough reflex sensitivity and severity. Despite promising results there now needs to be further work to optimise these interventions. There is a need to standardise terminology used such as relabelling the intervention as cough control therapy and move away from uni-disciplinary terms. Standardised patient selection, including screening protocols, optimal timing and delivery of the interventions as well as the outcome measures used to evaluate interventions need further exploration
