1 Biomedical Engineering Image Formation PD Dr. Frank G. Zöllner Computer Assisted Clinical Medicine Medical Faculty Mannheim Learning objectives! Understanding the process of image formation! Point spread function and its properties! Noise! Fourier Transformation and its properties! Sampling Theorem PD Dr. Zöllner I Folie 6 I 9/9/2014 1
2 Diagnostic Imaging: Milestones 1901 W. C. Röntgen (Germany, ) discovery of X-rays 1952 Felix Bloch (USA, ) Edward M. Purcell (USA, ) development of a new precision method of nuclear magnetism (NMR) 1979 Allan M. Cormack (USA, ) Godfrey N. Hounsfield (UK, ) development of Computer-Tomography (CT) 1991 Richard R. Ernst (CH, ) development of high resolution magnetic resonance spectroscopy (MRS) 2003 Paul C. Lauterbur (USA, ) Peter Mansfield (UK, ) development of magnetic resonance imaging (MRI) PD Dr. Zöllner I Folie 7 I 9/9/2014 Diagnostic Imaging: Pioneers ROE PET The Making of a Science CT MRI source: ECR Newsletter 1/2003 PD Dr. Zöllner I Folie 8 I 9/9/2014 2
3 Why do we need imaging systems? Addiction to image information? source: Siemens 100 Jahre Röntgen, 1995 PD Dr. Zöllner I Folie 9 I 9/9/2014 Image Formation! process to generate (form) an image?! everyday images mostly 2D! however: objects in real world are 3D " eye s retina collects 2D images " brain reconstructs 3D objects PD Dr. Zöllner I Folie 10 I 9/9/2014 3
4 Image Formation! Can we describe this process by an equation? image object Imaging system PD Dr. Zöllner I Folie 11 I 9/9/2014 Imaging Equation! most (medical) imaging is nonlinear! however: assume most parts of our imaging process is linear # e.g. object brightnes is scaled, also the brightness of the image is linear scaled # more important: allows to decompose complex objects into smaller ones PD Dr. Zöllner I Folie 12 I 9/9/2014 4
5 Point Objects PD Dr. Zöllner I Folie 13 I 9/9/2014 Sifting Integral Imaging equation in current context PD Dr. Zöllner I Folie 14 I 9/9/2014 5
6 Point spread function (PSF) PD Dr. Zöllner I Folie 15 I 9/9/2014 Point Spread Function (PSF) PD Dr. Zöllner I Folie 16 I 9/9/2014 6
7 Properties of the PSF! point sensitivity function # Integral over h total signal collected! spatial linearity # PSF can be shifted imaging system no longer a spatial linear transformation PD Dr. Zöllner I Folie 17 I 9/9/2014 Properties of PSF PD Dr. Zöllner I Folie 18 I 9/9/2014 7
8 Properties of the PSF If we know the PSF and the position of the imaging system is independant, the convolution integral characterises our system PD Dr. Zöllner I Folie 19 I 9/9/2014 Resolution! given by the FWHM! for symmetric Gaussian: FWHM = 2.35 d! if two Gaussian are combined but spaced 1 FWHM apart, the signal dips by 6% of the maximum (see b)! of course, other ways to measure resolution PD Dr. Zöllner I Folie 20 I 9/9/2014 8
9 Resolution! line pairs per unit length! mainly used in classical photographic imaging PD Dr. Zöllner I Folie 21 I 9/9/2014 Resolution! Differences in reproducing an object photographic or digital Siemensstern digital image photo film PD Dr. Zöllner I Folie 22 I 9/9/2014 9
10 Noise! variations in images are called noise! unpredictable, random, depends on the imaging system! becomes an irreversible addition to the image! Examples: # # # # PET: Poisson noise associated to radioactive decay MRI: eletronic noise CT: detector noise + reconstruction US: scattering PD Dr. Zöllner I Folie 23 I 9/9/2014 Noise PD Dr. Zöllner I Folie 24 I 9/9/
11 Noise! physiological noise of object relevant?! small animal imaging, e.g. by MRI! eletronic noise higher than physiological noise! solution to reduce noise?! cooling of electronics PD Dr. Zöllner I Folie 25 I 9/9/2014 Noise PD Dr. Zöllner I Folie 26 I 9/9/
12 Image Formation - Summary! image formation can be described mathematically # assume that it is a linear process # can be decomposed into point objects (delta functions)! point spread function describes imaging system # usually a smearing of the object in image space # determines resolution of the imaging system (fwhm)! Noise # additional signal to the image # random, unpredictable PD Dr. Zöllner I Folie 27 I 9/9/
