Claim 13

The device of claim 1, further comprising alignment indicator means for indicating alignment of the track and cylinder.

Claim 14

The device of claim 1, further comprising an orientation adjustment means slidably engaged with the track for adjusting the orientation of the track within a selected plane.

Claim 15

The device of claim 1, wherein the selected portion of the body is the head, and the body is in a reclining position, and further comprising head positioning means to support the head between the camera positioning means and the film support means.

Claim 16

A portable medical radiographic device for a radiological camera and radiologically sensitive film, comprising: (a) a mobile base; (b) an elongate supporting structure attached to the mobile base, the supporting structure comprising a plurality of sections and adjustable joints interconnecting the sections; (c) means for mounting the radiological camera at a selected position on a first one of the plurality of sections, the means for mounting comprising an elongated arcuate-shaped track for movably mounting the radiological camera on a concave portion thereof, so that rays from the radiological camera are directed away from the concave portion of the track; (d) means for supporting the radiologically sensitive film at a selected position on a second one of the plurality of sections, the means for supporting comprising an elongated arcuate-shaped cylinder for supporting a film cartridge containing the radiologically sensitive film in a concave portion thereof, so that the radiologically sensitive film is exposed by radiation directed towards the concave portion of the cylinder; the cylinder fixedly attached to the second one of the plurality of sections and offset therefrom so that, in a plane perpendicular to a longitudinal axis of the second one of the plurality of sections, a first line joining the intersection of the plane with a first point on the cylinder half-way between the longitudinal ends of the cylinder and the intersection of the plane with the longitudinal axis is not perpendicular to a second line tangent to the support at the first point; (e) energizable camera transport means for moving the radiological camera along the length of the elongated track; and (f) means for adjustably orienting the position of the track so that the concave portion of the track and the cylinder are positioned in opposition to one another, the first and second ones of the plurality of sections being selected so that when a selected portion of a body is interposed between the camera mounting means and the film support means, the radiological camera and the camera transport means are simultaneously energized, and the concave portions of the track and cylinder are positioned in opposition to one another the moving radiological camera exposes an elongated strip of the radiologically sensitive film, thereby creating a panoramic radiological image of the selected portion of the body.

Claim 17

A portable medical radiographic device for a radiological camera and radiologically sensitive film, comprising: (a) a mobile base; (b) an elongate supporting structure attached to the mobile base, the supporting structure comprising a plurality of sections and adjustable joints interconnecting the sections; (c) means for mounting the radiological camera at a selected position on a first one of the plurality of sections, the means for mounting comprising an elongated arcuate-shaped track for movably mounting the radiological camera on a concave portion thereof, so that rays from the radiological camera are directed away from the concave portion of the track; (d) means for supporting the radiologically sensitive film at a selected position on a second one of the plurality of sections, the means for supporting comprising an elongated arcuate-shaped cylinder for supporting a film cartridge containing the radiologically sensitive film in a concave portion thereof, so that the radiologically sensitive film is exposed by radiation directed towards the concave portion of the cylinder; the cylinder fixedly attached to the second one of the plurality of sections and offset therefrom so that, in a plane perpendicular to a longitudinal axis of the second one of the plurality of sections, a first line joining the intersection of the plane with a first point on the cylinder half-way between the longitudinal ends of the cylinder and the intersection of the plane with the longitudinal axis is not perpendicular to a second line tangent to the support at the first point; (e) energizable camera transport means for moving the radiological camera along the length of the elongated track; and (f) means for adjustably orienting the position of the track so that the concave portion of the track and the cylinder are positioned in opposition to one another, the first and second ones of the plurality of sections being selected so that when a selected portion of a body is interposed between the camera mounting means and the film support means, the radiological camera and the camera transport means are simultaneously energized, and the concave portions of the track and cylinder are positioned in opposition to one another the moving radiological camera exposes an elongated strip of the radiologically sensitive film, thereby creating a panoramic radiological image of the selected portion of the body.
