For each A-scan, 1000 repeated axial depth scans (M-mode scans) are performed at the same lateral point while the pump beam is amplitude modulated.
Multiple B-mode scans are performed during tumor debulking to evaluate the remaining capsule, in order not to trespass it causing damage to surrounding brain parenchyma and to evaluate complete resection, when achievable.
After the transmission scan, a 10-min list mode scan was started simultaneously with an intravenous injection of 185 MBq of 15O H2O (18.5 at 0.5 mL/s).
Then, contact mode scanning was immediately performed using a commercial AFM (AutoProbe CP Research, Thermomicroscopes, Sunnyvale, CA, USA) in air at room temperature.
Here, the 70% contour obtained by connecting the corresponding depths in individual A-mode scans is unreasonable because the SD value fluctuates fast along depth.
For each single point phase measurement, 60 A-mode scans were collected in 3 ms. The B- mode magnitude image of the tissue phantom is false colored using the photothermal signal in Fig. 4(d), clearly separating the region with nanoparticles from the region without them.
ioUS, an easily repeatable examination, and multiple B-mode scan are performed during tumor debulking, assessing constantly the thickness of the remaining lesion.
At two centers, 77 patients presenting with a solid mass on B-mode scan were studied at 7.5 MHz.
c If M-mode scanning is applied, a characteristic pattern called "seashore sign" is visible.
An M-mode scan was recorded over a whole respiratory cycle (Fig. 1b, c), and then, the image was frozen.
If M-mode scanning is applied to a B-mode scan showing a normal pleural line with lung sliding, the corresponding characteristic M-mode image is called the "seashore sign" [7].
