Summary:
|
Digital imaging is widely used in telemedicine, including surgery and even by pathologists for creation of static images using microscope-dedicated optical cameras. Recently this practice has even more urgency as many healthcare practices have to be done remotely, due to COVID-19. Such digital imagining for telemedicine is sometimes done using smartphones.
It is clear that robust diagnosis relies upon satisfactory cross-media colour reproduction between physical targets and digital images displayed on different displays and observed under disparate viewing conditions. For this reason, standardization on the use of colour in medical imaging is necessary.
The Digital Imaging and Communications in Medicine (DICOM) Grayscale Standard Display Function (GSDF) was developed to provide an objective, quantitative mechanism for mapping digital image values into a given range of luminance values in order to produce better visual consistency in the way images appear on diverse display devices. The DICOM GSDF is intended for use with grayscale images, such as x-ray images, MRI, CT, and ultrasound. As such, therefore, DICOM GSDF is not suitable as a standard to be used for UHD medical imaging.
With this background, the current draft Recommendation will describe requirements on the lighting, camera, transmission and displaying of colour, with specific reference to ultra-high definition imaging.
