Conventional ultrasound verifies soft- and hard-tissue features detected in LUS on the forearm. a Single time trace from LUS imaging of a volunteer’s forearm. b Photograph of a volunteer’s forearm region, imaged using LUS and conventional ultrasound. A green tracking laser from the LDV is also visible. c Reconstructed LUS image of a volunteer’s forearm with multiple visible tissue layers. d Matching conventional ultrasound image of the volunteer’s forearm using a GE Logiq E9 system and a 9 MHz linear probe confirming features detected in the LUS image.
