what is photo tray, and what is its  usage in the lab?

What you are referring to is probably one of the low, flat plastic trays used in the process of developing film and prints.  They are inexpensive, and can be handy for performing experiments where you need a large surface, but low volume of water -- such as the experiment where you calculate Avogadro's Number by determining the area covered by a droplet of a dilute solution of oleic acid.\n\nThey can also be useful for containing/controlling small parts that might roll away on a hard lab bench surface.\n\nJust a few ideas.

Print off the picture, cut out all areas that bacterial growth is observed and using a sensitive balance scale weigh the paper that has bacterial growth on it.  Works pretty good.

reflected light will dominate the picture so you meter the most effect

Digital Image Processing can mean getting photographic prints made, like Snapfish or Shutterfly.\n\nBut more importantly it means using computers to alter or enhance an image using mathematics.\n\nA simple example is using software called a photo editor to make changes to a picture. For instance PhotoShop, PaintShop, GIMP can be used to improve or modify a digital photograph.\n\nA more complicated example is modifying a movie or television image to improve its quality or to add special effects.\n\nDoctors and scientists sometimes use Digital Image Processing to get a better view of medical or scientific images.\n\nThe main advantage to Digital Image Processing over old fashioned (analog) processing is that it produces cleaner, less "noisy" images and has a wider range of functions.\n\nDIP is part of a wider range of computers and electronics called Digital Signal Processing. For instance, getting computers or robots to see the world around them.\n\nWouldn't it be way cool if robots could see and be able to help us in everyday life?

There is a software, Bibble, named after the brand cat.\n\nBibble helps a photographer to rectify certain faults of digital photo. The software calculates suitable corrected value of each pixel of the picture at an early stage of forming the digital photo. \n\nThis is the science behind Bibble.

So Depending on your specimen preparation and staining ie. light microscopy verus electron microscopy or other. you only need to zomm in to the particular cell of interest capture the image. software gives you histogram for that image. whether its grayscale or RGB doesn't really matter. you should be able to use boolean algebra to subtract out the background of physiological cells. you just do it three times for Red Green and BLUe for color images. There are programs that automatically do blob analysis like character recognition.

gamma camera   \nDefinition:\nA camera used in scintillation recording to make a visible record of the distribution and relative concentration of radioactive tracer elements in a sample that is undergoing scanning.A gamma camera is a complex device consisting of one or more detectors mounted on a gantry. It is connected to an acquisition system for operating the camera and for storing the images.\n\nThe system accumulates counts of gamma photons that are absorbed by a crystal in the camera, usually a large flat crystal of sodium iodide with thallium doping in a light-sealed housing. The crystal scintillates in response to incident gamma radiation: when the energy of an absorbed gamma photon is released, a faint flash of light is produced. This phenomenon is similar to the photoelectric effect. Photomultiplier tubes (PMT) behind the crystal detect the fluorescent flashes and a computer sums the fluorescent counts. The computer in turn constructs and displays a two dimensional image of the relative spatial count density on a monitor. This image then reflects the distribution and relative concentration of radioactive tracer elements present in the organs and tissues imaged.

I use Arc Soft Photo Studio with Photoshop

Picasa or Google Desktop will do the trick.

its a picture of an organ or bones.  We call it also x-ray cause it use X-ray. on that source you have a couple of picture.

I use Picture Project. It sorts by the date the pictures were taken.

It is used to contain the chemicals in the lab !!!

I've never used a Roche instrument, however I have used Kodak/Vitros systems. Kodak/Vitros is dry slide technology.\nIt can be a bit expensive however its a reliable instrument. The 950 is a nice machine if you do a lot of lab work and perform a lot of chemistry. The 250/500 models are good for small labs or perhaps doctor's office. I know this much, take the Na+ reagents out of the freezer when you begin to get low ont those slides. That reagent  needs to set out for 2 hrs before loading onto the instrument.\n\nBear in mind, when choosing any instrument for any section of the lab there are certain things to keep in mind: Maintainence schedule, Consumables, Reagent requirements, and of course Technical support and availability of serivce to make service calls.

search for CBIR on google u will get a no of resources. I had done one project related to this in c++. if u need any help mail me

A colony counter is an instrument used to count colonies of bacteria or other microorganisms growing on an agar plate. Early counters were merely lighted surfaces on which the plate was placed, with the colonies marked off with a felt-tipped pen on the outer surface of the plate while the operator kept the count manually. More recent counters attempt to count the colonies electronically, by identifying individual areas of dark and light according to automatic or user-set thresholds, and counting the resulting contrasting spots.\n\nSuch counters are used to estimate the density of microorganisms within a liquid culture. An appropriate dilution, or several dilutions within the estimated appropriate range, is spread using sterile technique on the agar plate, which is then incubated under the appropriate conditions for growth until individual colonies appear. Each colony marks the spot where a single organism was originally placed, thus the number of colonies on the plate equals the number of organisms within the volume of liquid spread on the plate. That concentration is then extrapolated by the known dilution from the original culture, to estimate the concentration of organisms within that original culture.\n\nThe maximum number of colonies which may be effectively counted on a single plate is somewhere between 100 and 1,000, depending on the size of the colony and the type of organism.
