Description
- 2. 2.
- Modo estático: Se emplea para hacer fototerapia en una banda específica. Static mode: It is used to make phototherapy in a specific band.
- 3. 3.
- Modo secuencial: Se emplea cuando se requiere aplicar diferentes bandas en forma secuencial en fototerapias combinada. Sequential mode: It is used when it is required to apply different bands sequentially in combined phototherapies.
- 4. Four.
- Modo de barrido: Se emplea para obtener la firma espectral en la región del visible e infrarrojo cercano para realizar fotodiagnóstico. Secuencialmente se activa cada banda espectral y se captura una imagen hasta cubrir toda la región del visible e infrarrojo cercano. Scanning mode: It is used to obtain the spectral signature in the region of visible and near infrared to perform photodiagnostic. Each spectral band is activated sequentially and an image is captured to cover the entire region of the visible and near infrared.
El sistema almacena las imágenes adquiridas en cada una de las bandas espectrales en un directorio establecido por el usuario y que permite contar con una base de datos. The system stores the images acquired in each of the spectral bands in a directory established by the user and that allows to have a database.
El circuito de control de las fuentes de radiación y adquisición de datos e imagen se controla mediante una aplicación software desarrollada para ello. La aplicación permite realizar dos funciones: controlar la energía que llega a la superficie del objeto a estudiar y adquirir las imágenes en cada banda espectral, según el modo de operación del sistema. The control circuit of the radiation sources and acquisition of data and image is controlled by a software application developed for it. The application allows two functions to be performed: control the energy that reaches the surface of the object to be studied and acquire the images in each spectral band, according to the mode of operation of the system.
Para ver los resultados se utiliza un visualizador. También ha sido desarrollada una aplicación software para mostrar los resultados en dos mapas 3D de la zona irradiada. En el primer mapa las imágenes RGB adquiridas en cada banda espectral se transforman en un mapa en el que cada píxel de la imagen se corresponde con la longitud de onda pico máxima reflejada por el objeto de estudio (Figura 8). Esto se realiza mediante una algoritmia matemática basada en los espacios de color. En el segundo mapa las imágenes RGB se transforman en un mapa en el que cada píxel se corresponde con un nivel de energía reflejada por el objeto de estudio y su correspondiente energía absorbida (Figura 9). La energía reflejada en cada banda espectral se calcula mediante la diferencia entre la radiación reflejada de la piel u objeto de estudio y la emitida por las fuentes (previamente calculada en la calibración del sistema con el patrón). To view the results a visualizer is used. A software application has also been developed to show the results on two 3D maps of the irradiated area. In the first map the RGB images acquired in each spectral band are transformed into a map in which each pixel of the image corresponds to the maximum peak wavelength reflected by the object of study (Figure 8). This is done through a mathematical algorithm based on color spaces. In the second map the RGB images are transformed into a map in which each pixel corresponds to a level of energy reflected by the object of study and its corresponding absorbed energy (Figure 9). The energy reflected in each spectral band is calculated by the difference between the radiation reflected from the skin or object of study and that emitted by the sources (previously calculated in the calibration of the system with the standard).
El software de visualización de resultados también realiza operaciones de análisis como son: comparación entre varias áreas de interés seleccionadas dentro de una misma imagen (por ejemplo, zona sana y enferma en la piel) o entre varias imágenes de bandas espectrales distintas; también realizar análisis estadísticos de los datos obtenidos, como histogramas del porcentaje de píxeles de una imagen en cada banda en función de la la longitud de onda pico reflejada por el objeto de estudio o representación de firmas espectrales en 2D y 3D. The results visualization software also performs analysis operations such as: comparison between several areas of interest selected within the same image (for example, healthy and diseased skin area) or between several images of different spectral bands; also perform statistical analysis of the data obtained, such as histograms of the percentage of pixels of an image in each band depending on the peak wavelength reflected by the object of study or representation of 2D and 3D spectral signatures.
