AI‐Powered Framework for Evaluating Drug Efficacy for Three‐Dimensional In Vitro Cancer Models in Robot‐Assisted Production

Advanced Robotics Research, EarlyView.
An AI‐powered, robot‐assisted framework automatically produces, images, and analyzes 3D tumor spheroids to evaluate drug efficacy. Integrated modules handle spheroid formation, live/dead staining, brightfield imaging, and automated image analysis, including spheroid segmentation, viability and metrics to assess the drug treatment efficacy. The workflow

Absorbed radiation dose in radiation synovectomy

The British Journal of Radiology, 1978
The intra-articular injection of colloids containing β-particle emitting radionuclides has been shown to help in controlling synovial inflammation in a range of joints (Ansell et al., 1963; Grahame et al., 1970; Gumpel, 1973; Menkes et al., 1977), and in the knee Gumpel and Coles (1975) have shown the technique to be the treatment of choice for the ...

Radiation dose in neuroradiological procedures

Neuroradiology, 1978
Radiation dose is cumulative in the radiosensitive organs. In neuroradiology the organ of particular interest is the eye. There is an immutable physical relationship between spatial resolution, signal-to-noise ratio (i.e., density discrimination), and dose: Dose alpha (formula: see text).
