This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Positron Corporation rather than just read about it. In short: Positron Corporation is an American nuclear medicine healthcare company specializing in cardiac Positron Emission Tomography (PET) imaging. Positron is headquartered in Niagara Falls, New York in addition to its clinical and technical cardiovascular PET training facility.

Key takeaways

Positron Corporation belongs to physics; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Positron Corporation to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Positron Corporation from memory before moving on to harder problems.

Reference excerpt

Positron Corporation is an American nuclear medicine healthcare company specializing in cardiac Positron Emission Tomography (PET) imaging. Positron is headquartered in Niagara Falls, New York in addition to its clinical and technical cardiovascular PET training facility. The company's products and services enable healthcare providers to diagnose cardiac disease and improve patient outcomes. Positron Corporation is a public company and traded on the Financial Industry Regulatory Authority, Inc.'s OTC Bulletin Board under the ticker symbol POSC.

History Positron was founded in 1983 as a research and development company.

Company development After its founding in 1983, Positron debuted a new time-of-flight tomograph called the POSICAM. Posicam used barium fluoride for the scintillation detector and was primarily used by researchers interested in cardiac imaging. In 1985, the FDA approved the POSICAM system for marketing and the following year, Positron began commercial operations. The FDA later gave approval to Positron to begin marketing its HZ PET imaging system in 1991. Positron received patents for aspects of its HZ and HZL POSICAM systems in 1993 along with FDA approval to market HZL. In 2005, Positron entered into a joint venture contract with Neusoft Medical Systems Co., Inc. of Shenyang, China for a jointly owned company to pursue the manufacturing of PET imaging equipment called Neusoft Positron Medical Systems Co. Ltd. The following year, Positron acquired a manufacturer/developer of nuclear imaging devices called IS2 Medical Systems, Inc. based in Ontario, Canada. Positron acquired DoseShield Corporation, a developer and manufacturer of automated radiopharmaceutical technology/systems in 2008. In 2009, Positron and its partner Neusoft Medical Systems received FDA approval to sell and distribute their Attrius PET system.

Attrius The Attrius is Positron's main cardiac PET system that the company provides in nuclear medicine that was launched in 2010. The system uses software to monitor coronary artery overlay display and open architecture for new protocol development and customization and motion correction. Other products include PosiRx, a system that simplifies and controls the procedures associated with the preparation and delivery of radiopharmaceuticals used in molecular imaging and PosiStar, Positron's customer care plan for Attrius.

Awards Positron Corporation is the winner of the 2010 North American Molecular Imagine Systems New Product Innovation Award given by the research firm Frost & Sullivan.

Worked examples

Example 1 — a first encounter with Positron Corporation

Start with the simplest possible case. Write down what Positron Corporation claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In physics, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Positron Corporation before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Positron Corporation ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Positron Corporation

In research: Positron Corporation appears in physics research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Positron Corporation in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Positron Corporation is common in secondary-school and first-year university syllabi. It links to neighbouring topics Health care companies based in Illinois, Medical imaging, Nuclear medicine organizations, so understanding it makes those chapters shorter.
In everyday life: Look for Positron Corporation outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
