Tele-diaphanography apparatus
First Claim
1. A tele-diaphanography apparatus suitable for transilluminating human or animal tissues, which apparatus comprises a first source of light of wavelength from 300 Nm to 2000 Nm, a first housing in which said first light source is mounted, a first light exit aperture in said first housing, a first means for directing onto the tissue to be examined transillumination light which is emitted by said first source of light through said first light exit aperture, a heat absorbing filter for absorbing infra-red radiation, said filter being located in the path of the light from said first light source to the tissues to be examined;
- a second source of light of wavelength from 300 Nm to 2000 Nm, a second housing in which said second light source is mounted, a second light exit aperture in said second housing, a second means for directing onto the tissues to be examined light which is emitted by said second source of light through said second exit aperture;
power supply means for controlling the first and second light sources;
means for connecting said first and second light sources to said power supply means;
a light detector for detecting the light emitted from said second light source and transmitted through the transilluminated tissue being examined, said light detector adapted to be positioned in use on the opposite side of the tissue from said second source of light;
a visual display unit connected to said light detector for displaying an image detected by said light detector; and
recording means for recording the image detected by said light detector.

Abstract
A tele-diaphanography apparatus suitable for transilluminating human or animal tissues, which apparatus comprises a first housing including a source of light of wavelength from 300 Nm to 2000 Nm; means for directing light from the first light source onto the tissues to be examined by transillumination, and a heat-absorbing filter located in the path of the light from the light source; a second housing including a source of light of wavelength from 300 Nm to 2000 Nm, and means for directing the light from the second light source onto the tissues to be examined; a light detector for detecting the light transmitted through the transilluminated tissue being examined; a visual display unit for displaying the image detected by the light detector; and recording means for recording the image detected by the light detector.

12. A tele-diaphanography apparatus suitable for transilluminating human or animal tissues, which apparatus comprises a source of light of wavelength from 300 Nm to 2000 Nm;
- a housing in which said light source is mounted;
a light exit aperture in said housing;
a first means, which is engageable with said housing, for directing onto the tissue to be examined transillumination light which is emitted by said light source through said light exit aperture;
a heat absorbing filter for absorbing infra-red radiation, said filter being mounted in said first means for directing so that when said first means for directing is engaged with said housing said filter is located in the path of the light from said light source to the tissues to be examined;
a second means, which is engageable with said housing, for directing onto the tissues to be examined transillumination light which is emitted by said light source through said light exit aperture, said first and second means for directing being selectively alternatively engageable with said housing so that light from said light source can be directed through either said first or said second means for directing as desired, power supply means for controlling said light source;
means for connecting said light source to said power supply means, a light detector for detecting the light which is emitted from said light source, directed through said second means for directing and transmitted through the transilluminated tissue adapted to be examined, said light detector being positioned in use on the opposite side of the tissue from said light source;
a visual display unit connected to said light detector for displaying an image detected by said light detector; and
recording means for recording the image detected by said light detector. - View Dependent Claims (13, 14, 15, 16, 17, 18)
