ECCV 2020 Daily - Wednesday

More than 50 million medical images were acquired last year in the UK alone (this figure excludes dental X-rays). Medical images are produced by several types of imaging device, ranging from 2D images such as standard planar X-rays, traditional ultrasound scans (see Fig. 2 ), and retinal photographs, to 3D volumetric images, such as computed tomography (CT), magnetic resonance imaging (MRI), positron emission tomography (PET), and optical coherence tomography (OCT). In his first talk, Keith Goatman briefly describes the medical scanners commonly found in hospitals today, covering over a hundred years of imaging innovation. He starts with Wilhelm Röntgen’s famous X-ray image of his wife’s hand (see Fig. 3 ) and ends with some cutting-edge technology that may one day become common in hospitals, such as 2 Tutorial 20 DAILY W e d n e s d a y 3 A picture of Wilhelm Röntgen's wife's hand from his 1895 publication demonstrating X-ray imaging for the first time. 4 Left: Standard planar (2D) chest X-ray (Canon CXDI flat panel detector); Right: Canon Precision ultra-high-resolution CT scanner (single coronal section). photo-acoustic imaging and fast field cycled MRI. He explains why a 3D CT image of the lung is more sensitive for detecting disease such as Covid-19 than a traditional 2D X-ray (see Fig. 4 ).
