The comprehensive analysis instrument comprises a biologic photographic microscope, a CCD camera, a digital image processing device, an image monitor, a computer and a result output device, wherein, the photographic device collects image information through the biologic microscope; the image information is sent to the computer image processing system after photoelectric conversion; simultaneously, image signals are measured or processed. The utility model has accurate test, no radiation to human bodies, low cost and convenient operation.

Description

Comprehensive analysis instrument for tumor image information

This utility model belongs to a kind of tumor image analytical equipment.

At present, there are planar defect down in common tumor detection devices such as CT and nuclear magnetic resonance scanner device: at first, and the testing cost height; Its two, these apparatus cost costlinesses, general hospital can't bear; Its three, the altofrequency electromagnetic wave that these instruments are launched has certain damage to tested patient; Its four, both detections all are that body is carried out tomoscan, the focus that is between the tomography can be by omission, in addition, these instruments are suitable for the apparent in view or serious patient of Zheng's shape, are unsuitable for extensive generaI investigation.

The purpose of this utility model is to overcome the deficiency of above-mentioned known technology, thereby provides a kind of detection accurate, and radiationless, cost is low, analyser easy to use.

The purpose of this utility model realizes in the following way:

The operation principle of this analyser is to utilize the high-resolution camera head, by biological microscope or biomedical photo acquisition image information, after opto-electronic conversion, deliver to Computerized image processing system, with pictorial display on image monitor, simultaneously the picture signal of being gathered is carried out selected parameter measurement or required image processing, draw analysis result.

This utility model comprises biological shooting microscope (1), CDD video camera (2), digital image processing apparatus (3), image monitor (4), computer (5) and output device (6) as a result, wherein: digital image processing apparatus (2) comprises high-performance digital image acquisition disposable plates, this disposable plates is by preamplifier, sync separator, high-speed video A/D, high-speed video D/A, the picture frame memorizer, the address date commutation circuit, fast address generator, the TV timing sequencer, control logic circuit, I/O decoder and phase-locked loop circuit are formed, print places on the optical microscope of band camera interface, after the signal of shooting output amplifies through preamplifier, being sent to high-speed video A/D is digitized into and is Digital Image Data, the picture frame memorizer is stored Digital Image Data, high-speed video D/A is reduced into image analoging signal with Digital Image Data and arrives display image on the professional video monitor, the TV timing sequencer produces TV time sequential pulse signal automatically, comprise line field synchronization pulse signal, row vertical blanking impulse signal, composite synchronizing pulse signal and composite blanking pulse signal, and these signals are sent to fast address generator and high-speed video D/A, control the work schedule of fast address generator, simultaneously on high-speed video D/A with the compound television image analogue signal of helping of image analoging signal, the fast address signal that fast address generator produces is delivered on the address bus of picture frame memorizer after being switched by address date commutation circuit and computer address signal, pass to control logic circuit after the control command decoding of I/O decoder with computer, after logical operations, control the each several part circuit working by control logic circuit, sync separator is isolated synchronization pulse and is sent to phase-locked loop circuit from the image analoging signal of input, carry out genlocing by phase-locked loop circuit.

This utility model compared with prior art has following advantage:

Detect accurately, draw materials conveniently, radiationless to human body, cost is low, and is easy and simple to handle.

Below in conjunction with drawings and Examples this utility model is further described:

Fig. 1 is this utility model circuit theory diagrams

In Fig. 1: (1) biological shooting microscope; (2) ccd video camera; (3) digital image processing apparatus; (4) image monitor; (5) computer; (6) output device as a result.

Biological shooting microscope (1) provides the biological specimen image of fine definition, CDD video camera (2) mainly is converted to the signal of telecommunication by opto-electronic conversion with picture signal, and input picture system, digital image processing apparatus (3) amplifies the signal of telecommunication of input through preamplifier, be converted to digital signal by A/D, and with its input picture frame memory, simultaneously, can remake an A/D conversion, the analogue signal of output is shown at image monitor (4), computer (5) adopts compatible 386 computers of IBM, has the CLQ-I special-purpose software, adopts Chinesizing interface and mouse action, can make things convenient for taking-up information from the picture frame memorizer promptly, carry out parameter measurement and with result output, output device (6) can be schemed result of calculation or the form of pathological replacement be exported by monitor with side directly perceived as a result, and is also printable.
