Imaging of gun shot injuries

Mechanism of injury

Some understanding of the factors that influence wounding capacity and pattern of injury may help the imaging assessment.  The main contributing factors are the type of firearm, projectile characteristics and the inherent characteristics of the wounded tissues.

Type of firearm  

The type of firearm influences the velocity of the projectile and given that e = m x v2, projectile velocity is a major contributor to the energy imparted to tissues and hence, to wounding capacity.

Projectile characteristics

Deformation : encased (jacketed) bullets used in higher velocity firearms tend to deform (“mushroom”) on impact. A deformed bullet decelerates faster, hence increasing local tissue damage

Tumbling: when a bullet hits its target, it loses its directional stability and is able to rotate around its short axis; for this reason, non-deformed bullets may sometimes be seen pointing towards the entry wound

Fragmentation:  generally occurs on impact of a non-jacketed or semi-jacketed bullet. As well as giving some clue to the bullet type/characteristics, fragmentation often leads to a telltale distribution of fragments spreading along the bullet course. Fragmentation gives important information about the mechanism and direction of injury.

Tissue characteristics

The global forensic imaging market size is estimated to reach USD 125.2 million by 2027, registering a CAGR of 10.6%, according to a new report by Grand View Research, Inc. The key factors such as increasing inclination towards a needless autopsy approach, improving accessibility towards imaging technologies, and rising global crime rates are driving the growth of the market.

Various religious, cultural, and psychological beliefs against the approach of traditional cut-open autopsy in several countries have propelled the growth of the market. For instance, the religious beliefs of Islamic, Jews, and Buddhism do not support the concept of the conventional autopsy on the corpse.

The growing acceptance of virtual autopsy images in court proceedings owing to its palatability and the ease of interpretation by lay viewers is driving the market. In addition, valuable information on crime scenes such as age, sex, date, and time of the incident, and injuries can be more accurately delineated using forensic imaging. This, in turn, has boosted the adoption rate of the technology.

The high cost of the imaging modalities and the reluctance of the pathologists in accepting these advanced technologies are the factors expected to impede the growth of the market. The pathologist refrains to use advanced imaging tools in their practice in a fear of losing their jobs and skills identity.

Forensic IR-UV-ALS Directional reflecting Photography System/Lab Equipment   OR-GZP1000

Product principle:

The photography system of IR & UV directional reflection, using the UV emission principle, through imaging of IR & UV (IR & UV camera), transfers the IR & UV image into the visible light pictures. The product is one directional reflection system researched and developed by integrating the professional digital single lens reflex. The product is the camera system integrating the following functions: searching, observing, photographing, saving and image processing in real-time etc., which makes the IR & UV photograph more convenient and rapid.

Electrical characteristics:

Battery voltage: DC12.6V

Battery capacity: 6000mAh

Charging current: 1A

UV wavelength: UV-365nm

Power: ≥48W

Major advantages:

Focal distance adjustable: conducting the focusing imaging within certain distance.

Photograph without contacting material evidence shot: Due to shooting under sunshine rather than in the dark room and without dark room cover.

Have very small destruction to DNA by adopting 365nm UV as well as to users. On the other hand, theUV is controlled in reflection tube as well as one projected after reflection, which even violates the irradiation of UV to users.

The import high-power integration UV LED adopted and air cooling system adopted in heat dissipation make the product close to normal temperature when working, which guarantees the stable work of the ultraviolet light source and long service life, and prevents the vibration.

Products uses:

Applicable for which the latent fingerprint of various smooth objects.

 The product operation introduction:

1. Fix the light source system and camera on the long installation board with tripod equipped, and focus well when finding smooth object, then the UV produces the uniform light effect in terms of the smooth objects. After holder is slightly adjusted, the red area is showed on the camera display screen, at this time, it’s the best location for shooting system and smooth objects, then shoot.
