For the purpose of 'owning' a number, the double and triple ring shall count as 2 or 3, respectively. Three marks will close an inning.
 
After a number is 'owned' by a team, the double and triple ring shall count as 2 or 3 times the numerical values, respectively. Winning the game:
 
a. The player/team that closes all innings first and has the most
   points, shall be declared the winner.
b. If both sides are tied on points, or have no points, the first
   player/team to close all innings shall be the winner.
c. If a player/team closes all innings first, and is behind in points,
   he/they must continue to score on any innings not closed until
   either the point deficit is made up, or the opponent has closed
   all innings.
 
It shall be the responsibility of the player to verify his score before removing his darts from the dartboard. The score remains as written if one or more darts has been removed from the dartboard. In accordance with the inherent "strategy" involved in the Cricket game, no alterations in score shall be allowed, after the fact.

Tungsten multileaf collimator (MCL) consists of dozens of independently moving tungsten slats, or tungsten leaves, which can collimate the beam into nearly arbitrary shapes. Multileaf collimators were first introduced in the 1960's in Japan as a means of replacing conventional blocks in 3D conformal radiation therapy (3DCRT). Today tungsten multileaf collimators are standard on most therapy linacs and enable modern techniques based on intensity modulation.

Key advantages of tungsten multileaf collimators include:

• Dynamic movement of tungsten leaves during delivery allows for intensity modulated fluence patterns not achievable with conventional blocks.
• Finite set of possible aperture shapes results in a reasonable solution space for inverse planning optimization for IMRT, VMAT, etc.
• Significantly more convenient than cutting custom blocks for every field.

Radiation is an effective tool within medicine for both diagnostics and treatment of patients. Techniques such as SPECT and PET utilise radioactive materials injected into the patient, which are then monitored by gamma cameras (SPECT) or scanners (PET) to detect the presence of tumours in the body. Due to tungsten has high density, excellent radiation attenuation properties, and environmental friendly, it is widely used to produce tungsten PET syringe shield.

Tungsten PET syringe shield magnetically docks with the PET dispensing pig. Designed to accept 3cc and 5cc B-D syringes, tungsten syringe shield places the needle inside the vial septum when engaged; the external calibration rod allows the precise volume to be withdrawn without a leaded glass viewing port, where high exposure levels cannot be adequately shielded.

Tungsten is an extremely dense metal, heavier than lead for the same size item. Tungsten darts are considerably more dense than brass or nickel/silver darts.

Higher density materials result in darts with smaller diameter, better "feel", and tighter possible groups on the dartboard. Tungsten is also very durable, so the machined grip will not wear down as rapidly as on brass or nickel/silver darts.

Tungsten is also very durable, so a high-density tungsten dart resists wear and the grip will last much longer. On softer metal darts, the grooves and rough knurling may wear down fairly quickly from skin acid, friction, and hitting other darts.

The billets that tungsten darts are made from consist of a variety of metals, including tungsten. To manufacture the blanks for machining tungsten darts, tungsten powder and other metals are blended and bonded by heat and pressure, resulting in a "sintered" material that we refer to as nickel-tungsten (or copper-tungsten, etc.) Common materials include tungsten, nickel, copper, and iron. The exact mix of materials varies considerably from one company to another, based on their requirements for density, cost, and ease of machining.

Tungsten darts cost more for several reasons: The metal is expensive, and since it is very dense, tungsten requires more effort to fabricate into darts.
