Tactile Imaging

Biomechanical mapping, transvaginal, with report

This technology was developed by a development partner, Artann Laboratories, within the scope of the NIA/NIH grants (Phases I-IV).

Biomechanics of the Female Pelvic Floor


Tactile Imaging is a medical imaging modality translating the sense of touch into a digital image. The tactile image is a function of P(x,y,z), where P is the pressure on soft tissue surface under applied deformation and x,y,z are coordinates where pressure P was measured. The tactile image is a pressure map on which the direction of tissue deformation must be specified [OJOG].

Functional Tactile Imaging translates muscle activity into dynamic pressure pattern P(x,y,t) for an area of interest, where t is time and x,y are coordinates where pressure P was measured.
It may include [Biomechanics]:
  1. muscle voluntary contraction,
  2. involuntary reflex contraction,
  3. involuntary relaxation,
  4. specific maneuvers.

Clinical Applications

Many of tissue or organ disorders and diseased conditions are significantly manifested in changes of their mechanical properties such as soft tissue elasticity, structure support, muscle mobility and contractile strength. Therefore, the biomechanical mapping of a human organ or tissue of interest opens new possibilities in medical imaging, diagnostic, targeted treatment and monitoring.
