Described herein is a head cooling system comprising: a source of compressed breathable gas; a vortex tube comprising an inlet, a hot gas outlet and a cold gas outlet, the inlet operably connected to the source of compressed breathable gas; and an interface for delivering cooled gas to a nasopharyngeal cavity in fluid communication with the cold gas outlet. The head cooling system may be used in a method to reduce neurodegeneration in a subject, for example neurodegeneration from ischemia, anoxia, cardiac arrest, trauma or neurodegenerative disease. The head cooling system may also be used in a method to prophylactically protect a subject at risk of neurodegeneration, for example neurodegeneration from ischemia, anoxia, cardiac arrest, trauma or neurodegenerative disease.

Mammalian head cooling system and method

A photoacoustic imaging apparatus is provided for medical or other imaging applications and also a method for calibrating this apparatus. The apparatus employs a sparse array of transducer elements and a reconstruction algorithm. Spatial calibration maps of the sparse array are used to optimize the reconstruction algorithm. The apparatus includes a laser producing a pulsed laser beam to illuminate a subject for imaging and generate photoacoustic waves. The transducers are fixedly mounted on a holder so as to form the sparse array. A photoacoustic (PA) waves are received by each transducer. The resultant analog signals from each transducer are amplified, filtered, and converted to digital signals in parallel by a data acquisition system which is operatively connected to a computer. The computer receives the digital signals and processes the digital signals by the algorithm based on iterative forward projection and back-projection in order to provide the image.

The invention discloses an electrotherapy device for generating specifically designed low frequency pulsed magnetic fields (Cnp waveforms). The device comprises a memory storing at least one digital Cnp waveform and a digital to analog converter converting the at least one digital Cnp waveform into an analog Cnp waveform for application to a subject. A processor communicates with the memory and is responsive to operator input and conditioning the memory to output the at least one digital Cnp waveform directly to the digital to analog converter thereby to bypass the processor. The electrotherapy device is useful for electrotherapy of a subject to modify a variety of clinical physiological, neurological and behavioural conditions.
