Medical Imaging in the [10¹²Hz - 10¹⁴Hz] Domain

Enormous efforts are made to achieve advances in image quality and acquisition time of today's standard medical imaging modalities as X-ray fluoroscopy, computed tomography, magnetic resonance and ultrasound. However, new principal diagnostic insights cannot be expected from the linear extension of the physical principles of these methods. In this paper a review is given on imaging modalities in the 10¹²Hz - 10¹⁴Hz domain that include new physical principles as terahertz and diffuse optical imaging or well known principles - that had been rejected some years ago and are recently raised to interest by detector advances - as thermography.
