Two of the current authors have previously reported a new thermographic technique for the examination of the breasts, utilizing liquid crystals embedded in elastomeric sheaths.18,19 The sheaths were individually contoured to the body by means of a vacuum. This method resulted in a good correlation with clinical and mammographic findings. A modification of this technique has been specifically adapted for contact thermography of the spine and extremities and is described in this paper. The currently reported adaptation also employs flexible, elastomeric “Flexi-Therm” sheaths containing thermally sensitive liquid crystals. However, they may now be contoured to the torso and extremities by means of a new device, an “air pillow.” Uniform skin contact and consistently reliable thermograms have been achieved.
