a train because it is harder to stop than the car. source: my knowledge and i learned this in class today. peutetrebelle.tumblr.com
Nuclear medicine flood field uniformity test how often is it done?
Daily, or every day that the camera is being used for studies on patients."Seven different quality control procedures are necessary for a general nuclear medicine camera: energy peaking, uniformity, efficiency, resolution, linearity, high calibration flood, and collimator integrity.Energy peaking. Daily, the technologist checks the peak of a known radioactive source by the camera's energy spectrum. The energy peak of the camera should correlate with the peak counts of the radionuclide source.Uniformity. Uniformity is a daily assessment to measure the camera's ability to produce uniform images of a uniform source or accurate images. A uniformity flood source of Tc-99m or Co-57 is placed on the detector of the camera and an image is taken. To ensure acceptable uniformity, quantitative analysis is performed. Quantitatively, the uniformity should be below 5% and preferably in the range of 3% with today's camera abilities.Efficiency. This analysis can be performed in combination with uniformity. Efficiency assesses the ability of the instrument to detect any radioactive disintegration emitted. When analyzing the efficiency in combination with the uniformity, the time can be noted and compared with previous uniformity floods. When analyzing the efficiency separately, a known amount of activity is counted and the activity converted to disintegrations per minute. The efficiency is calculated by dividing the counts per minute imaged by the calculated disintegrations per minute and multiplying by 100. Efficiency = (cpm/dpm) x 100.Resolution. Resolution is performed weekly and assesses the camera's ability to produce image detail and sharpness. This test is performed similar to the uniformity test; however, a resolution bar phantom is placed between the camera detector head and uniformity source to produce the resolution image. The images are assessed qualitatively to evaluate the resolution acceptability.Linearity. Linearity is performed with resolution and assesses the images for horizontal and vertical line straightness or linear lines.High calibration flood. A high-count flood (100 million counts or greater) is used as a calibration source for the system's images. This high-count flood is applied to static, dynamic, and single photon emission computed tomography (SPECT) images to improve image quality and decrease nonuniformities inherent in the system.Collimator integrity. Collimator integrity is performed annually (at minimum) by comparing the extrinsic and intrinsic uniformity floods. The collimator is inspected visually for damage such as dents.

Is India moving towards people management?
As India is an emerging market and a great pool of people or human resource, so we can say that yes India is moving towards people management with the increasing rate of organizations. The attrition rate, corruption, ethical issues, all can be handled by managing only the workforce of the organization. for example the biggest problem of Infosys in today's scenario is its people leaving the organization. For managing people, the organization should provide proper training, incentives and profits which can motivate the people associated with the company itself. Hence, yes India is slowly and gradually moving towards the people management.
