2 Real Time Linear Array Imaging What is Real Time Linear Array Imaging? Or Real Time Radiography (RTR)? 2

3 Real Time Linear Array Imaging It s Not This! Shoe Fitting Fluoroscope

4 Real Time Linear Array Imaging It s Also Not This! 4

5 Real Time Linear Array Imaging Real-Time Radiography, which is also sometimes known as real-time radioscopy, is an advanced radiographic nondestructive examination (NDE) technique in which x-rays or gamma rays are used to produce digital images of a component. Real-time radiography works by emitting radiation through an object, these rays then interact with either a special phosphor screen or flat panel detector containing microelectronic sensors, which gives off light when the interaction occurs, creating a digital image. 6

6 Real What is Time DR Linear Array Imaging Direct Radiography, (DR), is a filmless method of capturing an image using either a line detector, a flat panel detector or an array detector, (such as Rayscan). The image is converted instantly from an analog to a digital state; viewable on your computer. 7

7 Detector: Detection Principles Conversion of radiation to an electric signal: Direct Conversion Indirect Conversion Direct Conversion Indirect Conversion Radiation Radiation Photodiode Visible light (CsI) Digital signal Photodiode Digital signal 8

8 Digital Detection Principles Indirect detector Scintillator screen Photo diodes Scintillator screen Visible light Fiber glass bounds Incident X-ray s X-ray photons hit the scintillator screen CCD elements Electric signal Scintillator converts X-ray photons in visible light Photo diodes detect the visible light and return an electrical signal Advantages: Higher saturation Large dynamic range 9

9 Detector: Detection Principles Direct Detector Semi-conductor Collection array Semiconductor Electric charges Incident X-ray s Bump bonds X-ray photons hit the semi-conductor The semi-conductor converts X-ray photons in an electrical signal CMOS elements Advantages: Saves one conversion step compared to indirect detector No blur/spread Better signal quality 10 10

10 Detector: Detection Principles Direct Detector Semi-conductor materials: Germanium (Ge) Silicon (Si) Cadmium Telluride (CdTe) 11

11 Direct-Indirect Imaging Indirect Detection Direct Detection (RTD RAYSCAN) Similar to film-unsharpness No film-unsharpness 12

15 Detector: Array Array detector has multiple rows of detector lines Semi conductor type (expensive) Matrix of rows and columns 2 dimensions Dynamic range of 12 bit to 16 bit Around 300 frames per second Array detector 17
