Abstract
The utility model discloses a medical film scanner with size of 14*17 inches which belongs to the field of the medical film scanner. The medical film scanner is characterized in that on the basis of the traditional medical film scanner with size of 12*16 inches in type of 9800 xl, a strip lamp rack is used for connecting a strip lamp with a lens rack to make the strip lamp interlocked with the lens rack. Not only a set of actuating mechanisms is left out, but also the requirement for the continuous scanning of full number of the medical film with size of 14*17 inches can be met for the enlarged object distance; the resolution is 1200 DPA, so that the requirement for the least resolution of 300 DPA of the medical film is met too; the medical film scanner with size of 14*17 inches can scan various photos, photographic films, file films, and other transmittance manuscripts.
Description
Technical field
14 * 17 inch medical treatment Film scanner belongs to medical scanner field.
Background technology
At present at medical films such as the X-ray sheet of medical industry scanning such as common rabat, CT, nuclear-magnetisms, the general medical film scanner that adopts specialty is as feedback chip scanner such as Weida, Kodak, but because cost an arm and a leg, has only minority hospital to bear.Along with the tide arrival of film digitizing, the tele-medicine consultation of doctors, noncontact diagnosis, film is digitized into the problem that extensively will solve for hospital.The A3 flat bed scanner of the large format of traditional industries (A3 12 * 16 inch) scanner by installing the TMA tabula rasa additional as: MICROTEK SM9800XL UMAX2100XL EPSONGT10000+ etc. enter large hospital rapidly with price advantage.
Since a large amount of film of most hospital as: the size of Chest X-rays sheet is the nonstandard A3 of 14 * 17 inch.Our A3 scanning range of scanner has only 12 * 16 inch.So can only be as mathematics and auxiliary the use, scanning result does not meet film case method, can not be by typing film database, as splice exist uncertain.
At present, medical Film scanner that can single pass imaging 14 * 17 inch films on the market all is special-purpose, employing be the sheet mode that advances of drum-type, and have following tangible problem:
1. the sheet mode that advances of drum-type can not compatible common photographic film and transmission contribution such as photo;
2. application more complicated is difficult to popularize;
3. the cost height costs an arm and a leg.
Summary of the invention
For break through existing flat bed scanner scan medical film size restrictions and and the defectives such as compatibility of professional film scanner, the utility model provides a kind of medical film flat bed scanner, this medical film flat bed scanner can not only Polaroid scanning 14 * 17 inch medical film (X-ray sheet, CT sheet etc.), and can scan transmission contributions such as various photo photographic film files.
Of the present utility modelly be characterised in that it contains:
Base; On put the scanning form of 14 * 17 inch medical treatment film, it is inlaid on the groove of base upper surface;
Tube rack, upper end have a platform that exceeds above-mentioned medical film;
Transmitted light source, promptly fluorescent tube is fixed on the platform of above-mentioned tube rack;
Lens bracket, its both sides, upper surface link to each other with the tube rack bottom surface, and this lens bracket contains:
Transmitted light inlet is opened in the lens bracket upper surface, be positioned at fluorescent tube under;
Thrihedral reflector is separately fixed at along the transmitted light incident direction on three medial surfaces of lens bracket;
Optical lens, it is fixed in the lens bracket with support, and its camera lens faces through the transmitted light exit after the reflection, and it is an object distance with the vertical range of scanning form;
The CCD device, it is fixed on the lens bracket medial surface, and faces the emergent light exit of optical lens;
Belt clamp and belt perforation are opened respectively symmetrically on the sidewall of lens bracket horizontal direction;
Guide rail is horizontally fixed on about the lens bracket inboard on two walls, it and lens bracket sliding contact;
Gear train, is fixed on the transmission shaft of this far-end belt pulley with another belt pulley of the coaxial belt pulley that is connected of reduction gearing, the driving belt that passes belt clamp in the above-mentioned lens bracket and belt perforation, far-end and one one end and the other end is fixed on the spring of lens bracket inwall and constitutes at the gear reduction that is rotationally connected by the motor that is fixed on base end face, with motor shaft;
The lens bracket supporting seat is fixed on the base end face, it and the oil base plate sliding contact that is bonded in the lens bracket bottom surface.
It also has a loam cake, and its end and base one side are rotationally connected, and cushion pad is arranged between the opposite side of the other end and base, are also fixing a handle in the side that cushion pad is arranged.
Sweep through examination, realized blur-free imaging, and can full width collect the image of 14 * 17 inch rabats, resolution also satisfies the requirement of medical film.
Description of drawings
Fig. 1. the longitudinal section of 14 * 17 inch medical film scanners.
Fig. 2. the longitudinal section of the medical scanner of 9800XL type 12 * 16 inch.
Wherein 1 is loam cake, the 2nd, and fluorescent tube, 3 is 14 * 17 inch medical films, 4 is 14 * 17 inch scanning forms, the 6th, connect the rotating shaft of loam cake 1 and base 14 usefulness, the 19th, tube rack, the 7th, guide rail, the 8th, gear train, the 9th, CCD device, the 10th, camera lens, 11 is three catoptrons, the 12nd, and belt clamp, the 13rd, oil base plate, the 14th, base, the 15th, cushion pad, the 16th, handle, the 17th, lens bracket, the 5th, lens bracket block, the 18th, lens bracket supporting seat.
Medical film is 12 * 16 inch in Fig. 2, is 14 * 17 inch among Fig. 1.
Embodiment
Please contrast Fig. 1 and Fig. 2.Duoed a lens bracket than Fig. 2 in Fig. 1, lacked a sets of transmission mechanism, it had both made fluorescent tube and lens bracket interlock, simplify the structure, more object distance is increased, realized all number scanning of 14 * 17 inch medical treatment films.Its resolution is 1200DPA, still can satisfy the demand that medical film must reach 300DPA and resolution.
Under the structure prerequisite that does not change original mirror group structure, drive mechanism, body connection location, by basic pinhole imaging system principle, pull and stretch (object distance) enlarge (object height) with original object distance pull and stretch 9cm about, original 12 inch (object height) just become 14 inch, for the scan-image blur-free imaging will be changed original image distance to CCD, image height changes, and original picture point number (resolution) descends.The corresponding image height of turntable driving software changes, and the physical dimension of final imaging results and the corresponding size that is scanned original paper are equated.
