“Fill the two spoons with powder,” the instructions read.

“Smooth over. Adjust the opening between the spoons to the width of the nose. Tighten the shooter. Place the spoons under the nose. Sniff and shoot.”

It sounds like a step-by-step guide to snorting an illicit drug, but it was far from it. I was in a candy store with seafoam green walls, jars of exotic licorice on the shelves and hula-hoops hanging from the ceiling. And I was there to snort chocolate, nothing more.

The owner’s name is Mary Jean Dunsdon, but most people call her Watermelon, after the fruit she used to sell to nude sunbathers on Wreck Beach.

Watermelon has owned the Licorice Parlour on Commercial Drive in Vancouver for just over two years and learned about snorting chocolate last year.

She took a trip to Belgium, the birthplace of the phenomenon, to experience it — and to bring it back to Vancouver.

“I was just amazed when I heard it,” Watermelon said. “I get there and everybody’s eating stupid old truffles, and I’m like, ‘We’re here for the snorting chocolate!’ ”

Snorting (or sniffing) chocolate is the brainchild of chocolatier Dominique Persoone of The Chocolate Line in Bruges, Belgium.

The company’s website claims that because the nose is vital for tasting food, sniffing cocoa powder “will help enhance the pleasure of the chocolate experience.”

Members of the Rolling Stones were among the first to get satisfaction from Persoone’s invention at a birthday party for Charlie Watts and Ronnie Wood five years ago.

“The chocolate sniff is a mix of ginger and mint and it was originally intended as a joke,” The Chocolate Line’s Pascal Pardo wrote in an email.

But after news of the Stones’ sniffing session emerged, Persoone was overwhelmed with questions and orders.

Now, over 25,000 “chocolate shooters” — a plastic device used to catapult the product up a person’s nostrils — have been sold worldwide.

And since November, Watermelon’s customers have been snorting The Chocolate Line’s finely ground ginger-mint or raspberry-mint cocoa powder.

“As far as I know, I’m the only person in Canada” who carries snorting chocolate, she said.

Watermelon sells chocolate shooters with both flavours for $109, but casual chocoholics can also pop by the store for a $2 snort.

“When you snort it,” she said, “you kind of experience chocolate for a couple hours very subtly — without the caloric intake. It hits all the same pleasure receptors in the brain as if you were eating it.”

Researchers have found that ingesting chocolate triggers the release of the pleasure hormone dopamine, though information wasn’t available on the effects of snorting it.

The dangers of snorting candy made headlines last year when parents of students at a Rhode Island middle school were warned their children faced risk of nasal scarring, lung irritation or infection and fatal allergic reactions after it was discovered they had been snorting Smarties wafer candies.

But Watermelon said everyone seems to be enjoying snorting chocolate — in moderation — and she hasn’t had a negative response yet.

High school students pop by to snort with their friends, one woman visits for a snort on her way to yoga and Watermelon’s own 71-year-old mother bought a chocolate shooter to bring to parties.

“I think when you first inhale it, not a lot of people are snorters, per se, and so they’re all kind of shocked. There’s kind of this initial, like, ‘Oh, what’s happened to me!’

“Then the chocolate starts to fall down the back of the throat and this very pleasant look comes over their face. They quite like it after that.”

1. Field of the Invention
The present invention relates to an X-ray imaging apparatus that uses a multiple X-ray source, and in particular to an apparatus that provides an X-ray tomographic image.
2. Description of the Related Art
A multiple X-ray source that uses carbon nanotubes as cold cathodes is known. This publicly-known X-ray emission apparatus forms a two-dimensional X-ray source by using multiple X-ray tubes utilizing carbon nanotubes as cathodes that emit electrons and disposing X-ray radiation windows, for collecting the X-rays from the X-ray tube, in a two-dimensional arrangement. The X-rays emitted from the two-dimensional X-ray source of the X-ray emission apparatus pass through a subject and are irradiated upon an X-ray image detector. The X-ray image detector generates an image signal of the X-ray image based on the intensity of the irradiated X-rays. A collimater, in which capillaries are arranged two-dimensionally in a sieve-like form, is disposed between the two-dimensional X-ray source of the X-ray emission apparatus and the subject, so that the axial direction of the capillaries follows the same direction as the direction between the two-dimensional X-ray source and the subject (see Japanese Patent Laid-Open No. 2004-089445 (called “Patent Document 1” hereinafter)).
Meanwhile, a technique whereby a tomographic image of a subject is calculated based on transmitted X-ray images created using multiple X-ray sources is known. In this publicly-known technique, a radiation source that irradiates a target surface with an electron beam, causing the emission of X-rays, and forms the X-rays into beam form by passing them through a collimater hole, is used. Many collimater holes are provided on the surface. The X-rays that pass through the subject are sequentially detected by a radiation detector, while scanning the electron beam and sequentially switching the collimater hole. A transmitted image forming means obtains transmitted image information based on the detection signals from the radiation detector that hold subject image information for each pixel point. Because the X-rays enter into the radiation detector directly from the collimater holes, and almost no scattering rays enter, no scattering ray information is included in the transmitted image information; thus, three-dimensional image information that includes no scattering ray information can be obtained (see Japanese Patent Laid-Open No. 2000-060835 (hereinafter called “Patent Document 2”)).
The X-ray imaging system disclosed in Patent Document 2 is formed in a quadrangular cone shape, as viewed in the direction extending from the focal point to the detector. The detection target is therefore captured over a wide range in regions close to the detector, and over a narrow range in regions far from the detector. When this phenomenon is observed in the vicinity of the X-ray sources, projection data of the detection target cannot be acquired in the pitch interval between multiple X-ray sources. In other words, data missing regions arise in the pitch areas between X-ray sources. This problem becomes more marked the larger the enlargement rate of the imaging system is.
Another problem is the reciprocal relationship between scattering ray removal and X-ray usage efficiency. In conventional X-ray imaging, the cone angles of the quadrangular cone-shape formed by the X-ray beam are enlarged, increasing the X-ray usage efficiency, and a large subject region is captured at one time. However, when a large region is irradiated with X-rays at one time, the resolution of the image decreases due to scattering rays. Although a scattering ray suppression grid can be used to suppress such scattering rays, the scattering ray suppression grid is disadvantageous because it dampens valid straight rays as well. Patent Document 2 therefore reduces the cone angles, which reduces the scattering rays, but reducing the cone angles also causes a drop in the X-ray usage efficiency.

Lesson: Introduction to X-ray Imaging Apparatus

### Overview
In this lesson, we will learn about X-ray imaging apparatus, its history, and how it works. We will also explore the different components of an X-ray imaging apparatus and their functions. By the end of this lesson, you will be able to understand the basics of X-ray imaging and its applications in medicine, industry, and research.

### Section 1: Introduction to X-ray Imaging Apparatus

X-ray imaging apparatus, also known as X-ray machines or X-ray systems, are devices that produce X-ray images of objects or people. These images are used to diagnose medical conditions, inspect materials, and study natural phenomena. X-ray imaging was first discovered in 1895 by Wilhelm Conrad Roentgen, who received the Nobel Prize in Physics for his discovery. Since then, X-ray imaging has become an essential tool in medicine, industry, and research.

### Section 2: Components of an X-ray Imaging Apparatus

An X-ray imaging apparatus consists of several components that work together to produce high-quality X-ray images. These components include:

1. X-ray source: The X-ray source is a device that produces X-rays. It typically consists of a heated filament (cathode) that emits electrons and a metal target (anode) that absorbs the electrons and releases X-rays.

2. Collimator: The collimator is a device that shapes the X-ray beam into a narrow, focused beam. It contains a series of holes or slits that allow only the X-rays passing through them to reach the object being imaged.

3. Object: The object is the person or thing being imaged. It can be a human body, an animal, or an inanimate object like a machine part.

4. Detector: The detector is a device that converts the X-rays passing through the object into an electrical signal. This signal is then processed into an image. There are two types of detectors: film-based detectors and digital detectors.

5. Image processing software: Image processing software is used to enhance the quality of the X-ray image. It can adjust the contrast, brightness, and sharpness of the image to make it easier to interpret.

### Section 3: How X-ray Imaging Apparatus Works

When an X-ray source is activated, it produces a beam of X-rays that travel towards the object being imaged. The collimator shapes the X-ray beam into a narrow, focused beam that passes through the object. As the X-rays pass through the object, they interact with the atoms and molecules in the object, producing a pattern of absorption and scattering.

The X-rays that have not been absorbed or scattered by the object continue on to the detector. The detector converts the X-rays into an electrical signal, which is then processed into an X-ray image. The image shows the density of the object, with denser areas appearing white and less dense areas appearing black.

### Section 4: Applications of X-ray Imaging Apparatus

X-ray imaging apparatus have a wide range of applications in medicine, industry, and research. Some of these applications include:

1. Medical imaging: X-ray imaging is commonly used to diagnose bone fractures, lung infections, and other medical conditions.

2. Industrial inspection: X-ray imaging is used to inspect materials for defects, such as cracks or voids, and to ensure that they meet quality standards.

3. Archaeology: X-ray imaging is used to study ancient artifacts without damaging them.

4. Astronomy: X-ray imaging is used to study celestial objects, such as black holes and supernovae.

### Glossary
- X-ray: Electromagnetic radiation with wavelengths shorter than those of visible light.
- Cathode: The heated filament that emits electrons in an X-ray source.
- Anode: The metal target that absorbs electrons and releases X-rays in an X-ray source.
- Collimator: A device that shapes the X-ray beam into a narrow, focused beam.
- Detector: A device that converts X-rays into an electrical signal.
- Image processing software: Software used to enhance the quality of the X-ray image.

### Conclusion
In this lesson, we learned about X-ray imaging apparatus, their components, and how they work. We also explored the different applications of X-ray imaging in medicine, industry, and research. By understanding the basics of X-ray imaging, we can appreciate its importance in our daily lives and its potential for future advancements.

text: Waste. We are committed to minimising our environmental footprint, which includes minimising the waste we have generated and increasing our recycle rates.. For many years we have been working to minimise our contribution to general waste and ensure waste products are managed appropriately. This includes using designated bins for scrap metal and other industrial materials and strict procedures for disposing of hydrocarbons such as oil.. Improving recycling rates. Recently we have had a number of specific initiatives which have been implemented across our operations to improve recycling rates. The main initiative involved replacing bins in kitchens and meal rooms with better designed bins that are colour coded, signposted, and sized for each area and the level of use. At the same time individual bins at desks were removed.. In the first two months of the changes, municipal recycling rates doubled at Carrington and tripled at Kooragang.

text: I recently saw a cool article and video (below) on a new project from Other Lab, one of the most interesting groups in the Bay Area robotics scene.. The video gets into some inflatable robotics work that they are doing, with some really interesting potential applications around human-safe robots and medical robotics. However, what I found most interesting were some thoughts from Otherlab co-founder Saul Griffith on the impact that engineers can and do have on the world around them. The topic of how and how meaningfully we as engineers can affect the world really resonates with me and I am happy to see it get discussed in a larger forum. I couldn’t agree more with Saul’s challenge to all of today’s (and tomorrow’s) engineers: keep dreaming and stretching your notions of what is possible. The world is a canvas with infinite possibility for improvement and beauty.
