There is not a large market for UBM- thus, the choices are limited The Quantel unit is very fine, as is the Accutome Both have fine probes It’s all about the probe!, the generation of the image, the resolution And the functionality of the software…. I hear the new Sonomed unit is quite impressive. Their image quality is said, by experts , to be top notch with marked improvements on probe and image resolution. I would check those top three contenders.. Denice No financial interest I happen to use the AVISO unit myself, for reasons I am happy to discuss off line.

It will freeze up in the middle of a test lately and needs to restart and also having problem uploading into the server. I wonder if someone can suggest an ultrasound unit that can also perform UBM (high resolution ultrasound as the iCube). Our manager would like to have a few options so we can compare the prices. I have tried to do some research online but with very few to choose from. Thanks so much for your help and feed back.
