The patent’s assignee is Nemo Creativity Holding B.V. (Oosterbeek, Netherlands).News editors obtained the following quote from the background information suppli ed by the inventors:“In 2020 a total of 2.7 million people were diagnosed with cancer. The main method for diagnosingcancer is by taking a tissue biopsy for h istopathological examination. Unfortunately, the unbeknownstmisplacement of bio psy needles is a major cause for false negatives, leading to cancer being detect ed in alater stage and thereby decreasing the likelihood of curative cancer tre atment. Instrument misplacementalso affects the ability to provide adequate tre atment. For example, incorrect placement of ablationneedles plays a role in inc omplete treatment of tumors and thus causing the recurrence of cancer. Bothcore biopsies and ablations are predominantly performed under ultrasonic image-guida nce. Ultrasoundguidance is highly dependent on the human operator due to its lo w resolution and single plane image.Advanced imaging modalities, such as CT and MRI systems, can be used to obtain high-quality medicalimages in 3 dimensions. Under CT-guidance the most common technique is to position the needle before the scan is taken and verify it by taking the scan. This method requires multiple repeated scans wherein theneedle is repositioned until the desired position is finally found. Ideally, positional guidance of instrumentssuch as ablation and biopsy needles is performed under real-time and high-resolution image guidance.Unfortunately, most CT and MRI systems have a closed bore design and require add itional displays forclinicians to position instruments manually.
