Opened issue https://github.com/OHIF/Viewers/issues/2366. Following http://dicom.nema.org/medical/Dicom/2018d/output/chtml/part03/sect_C.7.6.3.html#sect_C.7.6.3.1.5, LUT Entries shall be 0 if the table entries value is 2^16. If numLutEntries is 0, there is no for loop and return empty lut array. Solution: const numLutEntries = lutDescriptor[0] ? lutDescriptor[0] : 65536; This is often used by Philips Ultrasound equipments.
