Definitions
- the invention consists of a digital system for guiding the process of taking biopsy samples using an X-ray image.
- the current biopsy devices are based on static images that are calculated in a deferred way and require the blind biopsy needle to be placed and then check that the needle has been correctly inserted; If the insertion is not correct, a new calculation is required to correct the position and a new image or test images.
- the closest state of the art constitutes systems for performing radiographs that use CCD-based detectors.
- the current biopsy systems are based on a system of two static images taken at different angles, from which the three-dimensional coordinates of the lesion to be analyzed or extracted can be calculated.
- the current systems are not able to provide information on the position of the device during the insertion of the device that allows its relocation to reach the lesion without errors, but they force it to be calculated after the complete insertion; that is, as the sampling needle is guided, different static images are taken to check the position of the needle. Therefore, these systems do not provide a real-time image of the needle and the sample and do not take into account the elasticity of the tissues or the changes of position by the previous biopsy shots, this entails a loss of precision of the shots of biopsy, which can compromise the final result.
- Stereotaxia from Greek: stereo, three-dimensional; taxis, positioning: surgical technique that allows precise location and access to internal structures through a small hole through the use of three-dimensional coordinates obtained from two radiological images taken according to two projections angles, axial tomography or magnetic resonance.
- the problems to be solved by the present invention include: allowing biopsy specialists to guide the sampling needle in real time, with greater precision, more reliability, faster and less trauma for the patient, making the process of taking of biopsy samples more effective in terms of cost. Provide a fast and real-time system that allows doctors to use contrasts or short-lived markers to enhance the image. take samples of very small or low contrast lesions.
- Indirect conversion X-ray capture procedure whereby X-ray photons become visible photons, then being detected by a video camera or similar circuit, where they are converted into an electrical signal.
- Direct conversion X-ray capture procedure whereby X-ray photons are converted into electrical charge that is collected in a suitable electronic circuit.
- Photon count Reading mode of the X-ray detector signal whereby each photon becomes a current pulse. If the pulse width exceeds a preset threshold value, the circuitry increases the number of photons by one unit. If the electronic noise is below the lower counting threshold, it will not affect the final result.
- Charge integration Reading mode of the X-ray detector signal by which each photon is converted into a certain amount of electric charge, proportional to its energy, which is stored in a capacitor. Every time a new photon arrives,
- the load is increased.
- the stored load is constantly increasing due to electronic noise, so periodically it is necessary to zero the capacitor. In this case, it may be more convenient to opt for
