Installed in 2017, the D320i features a modular design and an adjustable iTech scan head measuring 776 x 140 x 180mm, which Pindado says allows D-Series lasers to be installed in the most restrictive places.
The system will include a femtosecond pulse laser in industrial design, a fast scan head, lenses, an optical table,
Scanlab now extends its product portfolio via the ultra-compact BasiCube 14 scan head, a price-effective variant that features a larger 14mm aperture and mechanical compatibility with the well-established ScanCube series.
The reasons being high volume of patients, inadequate staffing, time constraints leading to lack of detailed history taking and physical examination, availability of free CT services, uncertainty on clinical diagnosis in most instances on part of some ED physicians; important factor being lack of awareness/implementation of internationally standardized guidelines as a reference before ordering CT scan.10 As a result of this study radiology department LRH devised and implemented radiology request forms for quality assurance for selection of both adults and children for CT scan head presenting to ED in order to ensure judicious and rational use of CT services in an emergency setting.
Accuracy is enhanced by a combination of a rigid structure, precision motion control, precise calibration and the optics contained in the scan head. The system's automated turntable accurately repositions the part for additional scans with no need for targets or software alignment.
The most common CT scan head finding in these patients were skull fractures (88 patients) followed by contusion (53 patients) (Table 2).
Scanlab has introduced an additional variant of its entry-level BasiCube scan head that enables the execution of highly elaborate laser jobs and more complex graphics for laser marking, subsurface glass engraving or similar applications.
The scan was fast enough to be capable of doing a fair few originals if you had to, taking less than 10 seconds to do the actual scan sweep, after which you could move the device while the scan head returns to its rest position, and setting up for the next scan in the process.
The STM scan head including the new TTT scan unit was tested by scanning a graphite sample (GYBS/1.7, type ZYB from NT-MDT) in air and at room temperature.
A new beam delivery system integrates both a programmable multi-axis servo gantry and a scan head, supported by proprietary LaserLinQ software, which harmonizes the action of both components moving the beam.
At the start of the looping video, the vertical bar of a scan head travels across the screen slowly, back and forth with its cold light, as we see a fragmented hand wearing grown-out periwinkle nail polish, then a shot of a robotic lab dropper and petri dish.
The enhancements and refinements can reduce the size of the scan head and lower its cost, both of which expand the utility of the ChromaID technology and scope of its possible applications.
