Comparison studies between both the newer Philips Epiq and GE Logiq machines also identified significant differences in image quality, proving the Philips Epiq was more efficient.
The radiology department found it would be beneficial having two identical ultrasound machines by replacing the current GE Logiq with a second Phillips Epiq and upgrading the current Philips Epiq.
The total cost for the replacement machine and the software upgrade is $168,575.04, falling within the District Health Board's budget.
The spokesman said the order for the machine has already been placed and the expected delivery and commissioning will be within six to eight weeks.
Aside from this purchase, as part of an equipment upgrade, the hospital acquired a new CT scanner earlier this year at the cost of more than $800,000.
"Radiology staff are delighted with it and see it as a significant boost for patients," he said.
